EDR (Endpoint Detection and Response) solutions monitor endpoint activities in real-time and can prevent malicious files from being downloaded or executed by detecting suspicious behaviors. In this case, EDR would block the download or alert the security team.

DLP (Data Loss Prevention) prevents unauthorized data exfiltration rather than blocking malware downloads. FIM (File Integrity Monitoring) tracks changes to files but doesn’t prevent downloads. NAC (Network Access Control) controls device access to the network but does not directly block file downloads.

EDR's proactive blocking capabilities are covered under the Security Operations domain in SY0-701【6:Chapter 11†CompTIA Security+ Study Guide】.

When a zero-day vulnerability is discovered in mission-critical systems that require high availability, immediate patching is often not possible due to lack of available patches or the risk of disrupting critical operations. In such cases, the best practice is to implement compensating controls (such as increased monitoring, access controls, network segmentation, or web application firewalls) to mitigate risk until a patch or permanent solution can be safely applied.

Impossible travel (A)refers to logins fromgeographically distant locations within a time period that makes travel between them physically impossible. In this case, a user logging in fromChicago and Rome within a short timeframetriggers this anomaly.

This is a strong indicator of acompromised accountorstolen credentialsbeing used elsewhere.

Social engineering is the practice of manipulating people into performing actions or divulging confidential information, often by impersonating someone else or creating a sense of urgency or trust. The suspicious caller in this scenario was trying to use social engineering to trick the user into giving away credit card information by pretending to be the CFO and asking for a payment. The user recognized this as a potential scam and reported it to the IT help desk. The other topics are not relevant to this situation. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 19 1

After completing a vulnerability assessment and remediating the identified vulnerabilities, the next step is to rescan the network to verify that the vulnerabilities have been successfully fixed and no new vulnerabilities have been introduced. A vulnerability assessment is a process of identifying and evaluating the weaknesses and exposures in a network, system, or application that could be exploited by attackers. A vulnerability assessment typically involves using automated tools, such as scanners, to scan the network and generate a report of the findings. The report may include information such as the severity, impact, and remediation of the vulnerabilities. The operations team is responsible for applying the appropriate patches, updates, or configurations to address the vulnerabilities and reduce the risk to the network. A rescan is necessary to confirm that the remediation actions have been effective and that the network is secure.

Conducting an audit, initiating a penetration test, or submitting a report are not the next steps after completing a vulnerability assessment and remediating the vulnerabilities. An audit is a process of reviewing and verifying the compliance of the network with the established policies, standards, and regulations. An audit may be performed by internal or external auditors, and it may use the results of the vulnerability assessment as part of the evidence. However, an audit is not a mandatory step after a vulnerability assessment, and it does not validate the effectiveness of the remediation actions.

A penetration test is a process of simulating a real-world attack on the network to test the security defenses and identify any gaps or weaknesses. A penetration test may use the results of the vulnerability assessment as a starting point, but it goes beyond scanning and involves exploiting the vulnerabilities to gain access or cause damage. A penetration test may be performed after a vulnerability assessment, but only with the proper authorization, scope, and rules of engagement. A penetration test is not a substitute for a rescan, as it does not verify that the vulnerabilities have been fixed.

Submitting a report is a step that is done after the vulnerability assessment, but before the remediation. The report is a document that summarizes the findings and recommendations of the vulnerability assessment, and it is used to communicate the results to the stakeholders and the operations team. The report may also include a follow-up plan and a timeline for the remediation actions. However, submitting a report is not the final step after the remediation, as it does not confirm that the network is secure.

Business email compromise (BEC) is a type of targeted phishing attack where an attacker gains access to a legitimate business email account (or convincingly impersonates one) to manipulate financial transactions, such as redirecting payments to a fraudulent bank account. The scenario described matches this pattern.

The company should request a certification from the vendor that confirms the storage array has been disposed of securely and in compliance with the company’s policies and standards. A certification provides evidence that the vendor has followed the proper procedures and methods to destroy the classified data and prevent unauthorized access or recovery. A certification may also include details such as the date, time, location, and method of disposal, as well as the names and signatures of the personnel involved. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 3, page 1441

Abug bounty programencourages ethical hackers tofind and report vulnerabilities, helping organizations discover security flaws before they are exploited by malicious actors. Unlikevulnerability scans, bug bounty programs usereal-world testing techniques.

 Non-repudiation is the ability to prove that a message or document was sent or signed by a particular person, and that the person cannot deny sending or signing it. Non-repudiation can be achieved by using cryptographic techniques, such as hashing and digital signatures, that can verify the authenticity and integrity of the message or document. Non-repudiation can be useful for legal, financial, or contractual purposes, as it can provide evidence of the origin and content of the message or document. References = Non-repudiation – CompTIA Security+ SY0-701 – 1.2, CompTIA Security+ SY0-301: 6.1 – Non-repudiation, CompTIA Security+ (SY0-701) Certification Exam Objectives, Domain 1.2, page 2.

ARP poisoning(also known as ARP spoofing) is a basicman-in-the-middle (MITM)attack that involves sending fake ARP responses to redirect traffic. This technique isnot sophisticatedand can be easily executed using freely available tools like Cain & Abel, Ettercap, or Wireshark.

Such attacks are often attempted byunskilled attackers (script kiddies)testing their abilities, especially in environments like schools. The term“unskilled attacker”fits best here, as credential stuffing and DMARC are unrelated to ARP poisoning.

 A risk register is a document that records and tracks the risks associated with a project, system, or organization. A risk register typically includes information such as the risk description, the risk owner, the risk probability, the risk impact, the risk level, the risk response strategy, and the risk status. A risk register can help identify, assess, prioritize, monitor, and control risks, as well as communicate them to relevant stakeholders. A risk register can also help document the risk tolerance and thresholds of an organization, which are the acceptable levels of risk exposure and the criteria for escalating or mitigating risks. References = CompTIA Security+ Certification Exam Objectives, Domain 5.1: Explain the importance of policies, plans, and procedures related to organizational security. CompTIA Security+ Study Guide (SY0-701), Chapter 5: Governance, Risk, and Compliance, page 211. CompTIA Security+ Certification Guide, Chapter 2: Risk Management, page 33. CompTIA Security+ Certification Exam SY0-701 Practice Test 1, Question 4.

SASE stands for Secure Access Service Edge. It is a cloud-based service that combines network and security functions into a single integrated solution. SASE can help reduce traffic on the VPN and internet circuit by providing secure and optimized access to the data center and cloud applications for remote employees. SASE can also monitor and enforce security policies on the remote employee internet traffic, regardless of their location or device. SASE can offer benefits such as lower costs, improved performance, scalability, and flexibility compared to traditional VPN solutions. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 457-458 1

SQL injection is a type of attack that exploits a database misconfiguration or a flaw in the application code that interacts with the database. An attacker can inject malicious SQL statements into the user input fields or the URL parameters that are sent to the database server. These statements can then execute unauthorized commands, such as reading, modifying, deleting, or creating data, or even taking over the database server. SQL injection can compromise the confidentiality, integrity, and availability of the data and the system. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 215 1

Virtualization (D)allows multiple systems and services to be hosted onfewer physical machines, therebyreducing the total number of physical devicesand consequently thehardware attack surface. This also allows for better patching, monitoring, and control.

The fewer devices you manage physically, the fewer entry points there are for attackers to exploit hardware-level vulnerabilities.

LDAP authentication on the printer (C)would require users toauthenticate before printing, enablingsecure print release. This ensures that documents arenot printed until the authorized user is physically present, which directly addresses the issue of missing confidential documents.

As perCompTIA Security+ SY0-701, Domain 3.1 (Access management), integratingauthentication mechanisms like LDAPimproves physical and document security in shared environments.

Segmentation is a technique that divides a network into smaller subnetworks or segments, each with its own security policies and controls. Segmentation can help mitigate network access vulnerabilities in legacy loT devices by isolating them from other devices and systems, reducing their attack surface and limiting the potential impact of a breach. Segmentation can also improve network performance and efficiency by reducing congestion and traffic. Patching, insurance, and replacement are other possible strategies to deal with network access vulnerabilities, but they may not be feasible or effective in the short term. Patching may not be available or compatible for legacy loT devices, insurance may not cover the costs or damages of a cyberattack, and replacement may be expensive and time-consuming. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 142-143

Code signing (D)usescryptographic digital signaturesto confirm theintegrity and authenticityof software code. It ensures that the code hasnot been alteredafter being signed, providing assurance that the application is trustworthy.

This aligns withCompTIA Security+ SY0-701 Domain 2.3: Application security techniques, which includescode signingas a method to validatecode integrity.

"Network segmentation is a security practice that divides a network into smaller, isolated segments to limit access and reduce the attack surface. Firewalls are commonly used to enforce segmentation by creating rules that allow or deny traffic based on source, destination, and port. Tomeet compliance requirements, such as restricting access to internal servers, firewall rules can be configured to block all external traffic while permitting only authorized internal systems to communicate with the segmented servers. This ensures that sensitive resources are isolated from unauthorized access."

A Service Level Agreement (SLA) defines the expectations between service providers and customers, including response times, escalation procedures, and performance metrics. It ensures accountability and measurable service quality.

BPA (Blanket Purchase Agreement) relates to purchasing terms, MOA (Memorandum of Agreement) outlines responsibilities but is less specific on performance, NDA (Non-Disclosure Agreement) covers confidentiality.

SLAs are key in Security Program Management for managing vendor and internal service expectations【6:Chapter 16†CompTIA Security+ Study Guide】.

Preparation is the phase in the incident response process when a security analyst reviews roles and responsibilities, as well as the policies and procedures for handling incidents. Preparation also involves gathering and maintaining the necessary tools, resources, and contacts for responding to incidents. Preparation can help a security analyst to be ready and proactive when an incident occurs, as well as to reduce the impact and duration of the incident.

Some of the activities that a security analyst performs during the preparation phase are:

Defining the roles and responsibilities of the incident response team members, such as the incident manager, the incident coordinator, the technical lead, the communications lead, and the legal advisor.

Establishing the incident response plan, which outlines the objectives, scope, authority, and procedures for responding to incidents, as well as the escalation and reporting mechanisms.

Developing the incident response policy, which defines the types and categories of incidents, the severity levels, the notification and reporting requirements, and the roles and responsibilities of the stakeholders.

Creating the incident response playbook, which provides the step-by-step guidance and checklists for handling specific types of incidents, such as denial-of-service, ransomware, phishing, or data breach.

Acquiring and testing the incident response tools, such as network and host-based scanners, malware analysis tools, forensic tools, backup and recovery tools, and communication and collaboration tools.

Identifying and securing the incident response resources, such as the incident response team, the incident response location, the evidence storage, and the external support.

Building and maintaining the incident response contacts, such as the internal and external stakeholders, the law enforcement agencies, the regulatory bodies, and the media.

Software-defined networking (SDN) enables microsegmentation by allowing administrators to create fine-grained, dynamic network segments at the software layer independent of physical network topology. This capability isolates workloads and controls traffic flows between segments, enhancing security within data centers and cloud environments.

Next-generation firewalls (A) provide advanced filtering and inspection but do not inherently deliver the granular segmentation flexibility of SDN. Embedded systems (C) and air-gapped systems (D) refer to specific hardware or physical isolation techniques but do not implement microsegmentation as a network control method.

The concept of microsegmentation through SDN is detailed in the Security Architecture domain of the SY0-701 exam【6:Chapter 3†CompTIA Security+ Study Guide】.

Masking is a method to secure credit card data that involves replacing some or all of the digits with symbols, such as asterisks, dashes, or Xs, while leaving some of the original digits visible. Masking is best to use when a requirement is to see only the last four numbers on a credit card, as it can prevent unauthorized access to the full card number, while still allowing identification and verification of the cardholder. Masking does not alter the original data, unlike encryption, hashing, or tokenization, which use algorithms to transform the data into different formats.

IPSec is a protocol suite that provides secure communication over IP networks. IPSec can be used to create virtual private networks (VPNs) that encrypt and authenticate the data exchanged between two or more parties. IPSec can also provide data integrity, confidentiality, replay protection, and access control. A security consultant can use IPSec to gain secure, remote access to a client environment by establishing a VPN tunnel with the client’s network. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 8: Secure Protocols and Services, page 385 1

A Statement of Work (SOW) is a formal document detailing the scope, deliverables, timeline, and estimated hours for services such as penetration testing engagements.

BPA (Blanket Purchase Agreement) covers recurring purchases, SLA (Service Level Agreement) defines service quality expectations, and NDA (Non-Disclosure Agreement) protects confidentiality, none of which specify hours or detailed scope.

SOWs are fundamental in managing third-party risk and engagements, covered under Security Program Management【6:Chapter 16†CompTIA Security+ Study Guide】.

An engineer should recommend the decommissioning of a network device when the device poses a security risk or a compliance violation to the enterprise environment. A device that cannot meet the encryption standards or receive authorized updates is vulnerable to attacks and breaches, and may expose sensitive data or compromise network integrity. Therefore, such a device should be removed from the network and replaced with a more secure and updated one.

A legacy server is a server that is running outdated or unsupported software or hardware, which may pose security risks and compatibility issues. A critical business application is an application that is essential for the operation and continuity of the business, such as accounting, payroll, or inventory management. A legacy server running a critical business application may be difficult to replace or upgrade, but it should not be left unsecured or exposed to potential threats.

One of the best ways to handle a legacy server running a critical business application is to harden it. Hardening is the process of applying security measures and configurations to a system to reduce its attack surface and vulnerability. Hardening a legacy server may involve steps such as:

Applying patches and updates to the operating system and the application, if available

Removing or disabling unnecessary services, features, or accounts

Configuring firewall rules and network access control lists to restrict inbound and outbound traffic

Enabling encryption and authentication for data transmission and storage

Implementing logging and monitoring tools to detect and respond to anomalous or malicious activity

Performing regular backups and testing of the system and the application

Hardening a legacy server can help protect the critical business application from unauthorized access, modification, or disruption, while maintaining its functionality and availability. However, hardening a legacy server is not a permanent solution, and it may not be sufficient to address all the security issues and challenges posed by the outdated or unsupported system. Therefore, it is advisable to plan for the eventual decommissioning or migration of the legacy server to a more secure and modern platform, as soon as possible.

An Access Control List (ACL) is a technical mechanism used to explicitly define permissions for files, folders, or other resources. ACLs specify which users or system processes are granted access to objects and what operations are allowed on given objects. This allows the administrator to centrally and granularly manage file permissions for a group or team.

A hot site is a fully operational data center equipped with hardware, software, and network connectivity, ready for immediate use after a disaster. It allows near-zero downtime, making it ideal for critical systems needing continuous operations.

Warm sites (B) have some infrastructure but require additional setup time. Cold sites (D) provide space and power but no equipment, leading to longer recovery. Geolocation (C) is unrelated.

Hot sites are a key disaster recovery solution discussed in SY0-701's Resilience and Recovery domain【6:Chapter 9†CompTIA Security+ Study Guide】.

 An ISOW is a document that outlines the project, the cost, and the completion time frame for a security company to provide a service to a client. ISOW stands for Information Security Operations Work, and it is a type of contract that specifies the scope, deliverables, milestones, and payment terms of a security project. An ISOW is usually used for one-time or short-term projects that have a clear and defined objective and outcome. For example, an ISOW can be used for a security assessment, a penetration test, a security audit, or a security training.

The other options are not correct because they are not documents that outline the project, the cost, and the completion time frame for a security company to provide a service to a client. A MSA is a master service agreement, which is a type of contract that establishes the general terms and conditions for a long-term or ongoing relationship between a security company and a client. A MSA does not specify the details of each individual project, but rather sets the framework for future projects that will be governed by separate statements of work (SOWs). A SLA is a servicelevel agreement, which is a type of contract that defines the quality and performance standards for a security service provided by a security company to a client. A SLA usually includes the metrics, targets, responsibilities, and penalties for measuring and ensuring the service level. A BPA is a business partnership agreement, which is a type of contract that establishes the roles and expectations for a strategic alliance between two or more security companies that collaborate to provide a joint service to a client. A BPA usually covers the objectives, benefits, risks, and obligations of the partnership. References = CompTIA Security+ Study Guide (SY0-701), Chapter 8: Governance, Risk, and Compliance, page 387. Professor Messer’s CompTIA SY0-701 Security+ Training Course, Section 8.2: Compliance and Controls, video: Contracts and Agreements (5:12).

OSINT (Open Source Intelligence) involves collecting publicly available information, including data breaches, leaked credentials, and other exposed company data found online or on the dark web. OSINT tools can discover if a company’s information has been compromised publicly.

SIEM (Security Information and Event Management) monitors internal logs and events but does not collect external breach info. CVE (Common Vulnerabilities and Exposures) is a database of known software vulnerabilities, not breach data. CVSS (Common Vulnerability Scoring System) rates vulnerabilities' severity.

OSINT is a key technique in the Threats and Vulnerabilities domain for external threat intelligence gathering【6:Chapter 2†CompTIA Security+ Study Guide】.

Detailed Explanation:A Memorandum of Agreement (MOA) outlines terms of cooperation, including restrictions on sharing intellectual property. A breach indicates the terms of the agreement were violated, compromising confidentiality or usage terms. Reference: CompTIASecurity+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: "Third-Party Risk Management"​​.

Recovery Point Objective (RPO) defines the maximum acceptable amount of data loss measured in time. It directly impacts how frequently backups should occur to ensure data can be restored to a point no older than the RPO after a disruption.

Recovery Time Objective (RTO) (A) defines how quickly systems must be restored but does not dictate backup frequency. Mean Time To Repair (MTTR) (C) and Mean Time Between Failures (MTBF) (D) relate to system repair and reliability metrics, not backup schedules.

Understanding and defining RPO is a key part of the Business Impact Analysis (BIA) process covered in the Risk Management domain【6:Chapter 17†CompTIA Security+ Study Guide】.

Input sanitization is a critical security measure to prevent SQL injection attacks, which occur when an attacker exploits vulnerabilities in a website's input fields to execute malicious SQL code. By properly sanitizing and validating all user inputs, developers can prevent malicious code from being executed, thereby securing the website against such attacks.

Whaling is a type of phishing attack that targets high-profile individuals, such as executives, celebrities, or politicians. The attacker impersonates someone with authority or influence and tries to trick the victim into performing an action, such as transferring money, revealing sensitive information, or clicking on a malicious link. Whaling is also called CEO fraud or business email compromise2.

The act described is espionage, where classified information is stolen and provided to adversaries or unauthorized parties, usually for political, military, or strategic advantage.

Data exfiltration (B) is the technical act of stealing data but doesn’t specify motivation. Financial gain (C) or blackmail (D) could be motivations but are not clearly indicated here.

Espionage is a classic threat actor motivation outlined in the Threats domain【6:Chapter 2†CompTIA Security+ Study Guide】.

Data masking replaces sensitive data with realistic but fictional data, preserving format and usability while protecting confidential information during testing in environments like UAT (User Acceptance Testing).

Tokenization (B) replaces data with tokens but is more common for payment data in production. Obfuscation (C) scrambles data but is less structured than masking. Encryption (D) protects data confidentiality but may not be practical for testing.

Data masking is a best practice for protecting sensitive data in non-production environments covered in the General Security Concepts domain【6:Chapter 7†CompTIA Security+ Study Guide】.

To analyze malware behavior in detail, the best approach is toexecute the malware in a sandbox (D)andcapture its network activity. This providesreal-time analysisof how the malware behaves, spreads, and communicates.

This method is highlighted inDomain 2.1under"Analyzing indicators of compromise"and usingsandboxing and packet captureto study malware.

A self-signed certificate is a certificate that is signed by its own private key rather than by a trusted certificate authority (CA). This means that the authenticity of the certificate relies solely on the issuer's own authority. If a spoofed identity was detected, it could indicate that a private key associated with a self-signed certificate was compromised. Self-signed certificates are often used internally within organizations, but they carry higher risks since they are not validated by a third-party CA, making them more susceptible to spoofing.

802.1X is a network access control protocol that provides an authentication mechanism to devices trying to connect to a LAN or WLAN. It supports the use of certificates for authentication, can quarantine unapproved devices, and ensures that only approved and updated devices can access network resources. This protocol best meets the requirements of securing both wired and wireless networks with internal certificates.

A disaster recovery plan (DRP) is a set of policies and procedures that aim to restore the normal operations of an organization in the event of a system failure, natural disaster, or other emergency. A DRP typically includes the following elements:

A risk assessment that identifies the potential threats and impacts to the organization’s critical assets and processes.

A business impact analysis that prioritizes the recovery of the most essential functions and data.

A recovery strategy that defines the roles and responsibilities of the recovery team, the resources and tools needed, and the steps to follow to restore the system.

A testing and maintenance plan that ensures the DRP is updated and validated regularly. A DRP is required for an organization to properly manage its restore process in the event of system failure, as it provides a clear and structured framework for recovering from a disaster and minimizing the downtime and data loss. References = CompTIA Security+ Study Guide (SY0-701), Chapter 7: Resilience and Recovery, page 325.

Comprehensive and Detailed In-Depth Explanation:

User awareness training is essential in preventing security incidents caused by human error, such as clicking on malicious links. Employees need to be educated on recognizing phishing attempts, verifying email senders, and avoiding suspicious downloads.

Network monitoringdetects and alerts on malicious activity but does not prevent employees from clicking on harmful links.

Endpoint protectioncan mitigate malware infections but is not foolproof, especially if users continue to fall for phishing attacks.

Data loss prevention (DLP)can prevent data exfiltration but does not stop malware from being introduced into the system.

By training employees to recognize and avoid phishing scams, organizations canreduce the risk of malware infections and data breaches.

Multi-Factor Authentication (MFA) and patch management are both examples of preventative and technical controls. MFA prevents unauthorized access by requiring multiple forms of verification, and patch management ensures that systems are protected against vulnerabilities by applying updates. Both of these controls are implemented using technical methods, and they work to prevent security incidents before they occur.

The most important security concern when using legacy systems is the lack of vendor support. Without support from the vendor, systems may not receive critical security patches and updates, leaving them vulnerable to exploitation. This lack of support can result in increased risk of security breaches, as vulnerabilities discovered in the software may never be addressed.

References = CompTIA Security+ SY0-701 study materials, particularly in the context of risk management and the challenges posed by legacy systems​​.

Federation is an access management concept that allows users to authenticate once and access multiple resources or services across different domains or organizations. Federation relies on a trusted third party that stores the user’s credentials and provides them to the requested resources or services without exposing them. Password complexity is a security measure that requires users to create passwords that meet certain criteria, such as length, character types, and uniqueness. Password complexity can help prevent brute-force attacks, password guessing, and credential stuffing by making passwords harder to crack or guess. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 308-309 and 312-313 1

A change management procedure is a set of steps and guidelines that a security administrator should adhere to when setting up a new set of firewall rules. A firewall is a device or software that can filter, block, or allow network traffic based on predefined rules or policies. A firewall rule is a statement that defines the criteria and action for a firewall to apply to a packet or a connection. For example, a firewall rule can allow or deny traffic based on the source and destination IP addresses, ports, protocols, or applications. Setting up a new set of firewall rules is a type of change that can affect the security, performance, and functionality of the network. Therefore, a change management procedure is necessary to ensure that the change is planned, tested, approved, implemented, documented, and reviewed in a controlled and consistent manner. A change management procedure typically includes the following elements:

A change request that describes the purpose, scope, impact, and benefits of the change, as well as the roles and responsibilities of the change owner, implementer, and approver.

A change assessment that evaluates the feasibility, risks, costs, and dependencies of the change, as well as the alternatives and contingency plans.

A change approval that authorizes the change to proceed to the implementation stage, based on the criteria and thresholds defined by the change policy.

A change implementation that executes the change according to the plan and schedule, and verifies the results and outcomes of the change.

A change documentation that records the details and status of the change, as well as the lessons learned and best practices.

A change review that monitors and measures the performance and effectiveness of the change, and identifies any issues or gaps that need to be addressed or improved.

A change management procedure is important for a security administrator to adhere to when setting up a new set of firewall rules, as it can help to achieve the following objectives:

Enhance the security posture and compliance of the network by ensuring that the firewall rules are aligned with the security policies and standards, and that they do not introduce any vulnerabilities or conflicts.

Minimize the disruption and downtime of the network by ensuring that the firewall rules are tested and validated before deployment, and that they do not affect the availability or functionality of the network services or applications.

Improve the efficiency and quality of the network by ensuring that the firewall rules are optimized and updated according to the changing needs and demands of the network users and stakeholders, and that they do not cause any performance or compatibility issues.

Increase the accountability and transparency of the network by ensuring that the firewall rules are documented and reviewed regularly, and that they are traceable and auditable by the relevant authorities and parties.

The other options are not correct because they are not related to the process of setting up a new set of firewall rules. A disaster recovery plan is a set of policies and procedures that aim to restore the normal operations of an organization in the event of a system failure, natural disaster, or other emergency. An incident response procedure is a set of steps and guidelines that aim to contain, analyze, eradicate, and recover from a security incident, such as a cyberattack, data breach, or malware infection. A business continuity plan is a set of strategies and actions that aim to maintain the essential functions and operations of an organization during and after a disruptive event, such as a pandemic, power outage, or civil unrest. References = CompTIA Security+ Study Guide (SY0-701), Chapter 7: Resilience and Recovery, page 325. Professor Messer’s CompTIA SY0-701 Security+ Training Course, Section 1.3: Security Operations, video: Change Management (5:45).

Memory injection vulnerabilities allow unauthorized code or commands to be executed within a software program, leading to abnormal behavior such as generating outbound traffic over random high ports. This issue often arises from software not properly validating or encoding input, which can be exploited by attackers to inject malicious code.References: CompTIA Security+ SY0-701 course content and official CompTIA study resources.

VM escape allows an attacker to break out of a virtual machine to access the hypervisor or other adjacent virtual machines on the same host, effectively moving laterally to adjacent systems.

Side loading (B) involves loading malicious code in place of legitimate components. Remote code execution (C) allows running arbitrary code remotely. Resource exhaustion (D) causes denial of service by overusing resources.

VM escape is a known virtualization vulnerability detailed in SY0-701【6:Chapter 2†CompTIA Security+ Study Guide】.

Before applying any updates or patches to a production VM, especially one with a 99% uptime SLA, it is crucial to first take a snapshot of the VM. This snapshot serves as a backup that can be quickly restored in case the update causes any issues, ensuring that the system can be returned to its previous state without violating the SLA. This step mitigates risk and is a standard best practice in change management for critical systems.

References = CompTIA Security+ SY0-701 study materials, focusing on change management and backup strategies​​.

An image backup, also known as a full system backup, captures the entire contents of a system, including the operating system, applications, settings, and all data. This type of backup allows for a complete recovery of the system in case of a disaster, as it includes everything needed to restore the system to its previous state. This makes it the ideal choice for a systems administrator who needs to ensure the ability to recover the entire system, including the OS.

References = CompTIA Security+ SY0-701 study materials, domain on Security Operations​​.

When a legacy device is no longer receiving updates or patches, it is considered to be at the end of life (EOL). This means the manufacturer has ceased support for the device, and it will no longer receive updates, security patches, or technical assistance. EOL devices pose security risks and are often decommissioned or replaced.

End of support may seem similar but typically refers to the cessation of technical support, whereas EOL means the device is fully retired.

End of business and End of testing do not apply in this context​​.

 Sanitization is the process of removing sensitive data from a storage device or a system before it is disposed of or reused. Sanitization can be done by using software tools or hardware devices that overwrite the data with random patterns or zeros, making it unrecoverable. Sanitization is different from destruction, which is the physical damage of the storage device to render it unusable. Sanitization is also different from enumeration, which is the identification of network resources or devices, and inventory, which is the tracking of assets and their locations. The policy of securely wiping hard drives before sending decommissioned systems to recycling is an example of sanitization, as it ensures that no confidential data can be retrieved from the recycled devices. References = Secure Data Destruction – SY0-601 CompTIA Security+ : 2.7, video at 1:00; CompTIA Security+ SY0-701 Certification Study Guide, page 387.

To mitigate the risk of sensitive data being exfiltrated from the environment, the IT manager should implement a Data Loss Prevention (DLP) solution. DLP monitors and controls the movement of sensitive data, ensuring that unauthorized transfers are blocked and potential data breaches are prevented.

XDR (Extended Detection and Response) is useful for threat detection across multiple environments but doesn't specifically address data exfiltration.

SPF (Sender Policy Framework) helps prevent email spoofing, not data exfiltration.

DMARC (Domain-based Message Authentication, Reporting & Conformance) also addresses email security and spoofing, not data exfiltration​​.

Group policies can inadvertently introduce misconfigurations, such as enabling insecure settings or failing to disable legacy protocols, increasing vulnerabilities.

Zero-day (B) are previously unknown vulnerabilities, malicious updates (C) are attacker-controlled, and supply chain (D) risks come from third-party components.

Misconfiguration vulnerabilities are commonly introduced during changes and are emphasized in Security Operations【6:Chapter 14†CompTIA Security+ Study Guide】.

A web filter is a device or software that can monitor, block, or allow web traffic based on predefined rules or policies. One of the common methods of web filtering is to scan the URL for strings and deny access when matches are found. For example, a web filter can block access to websites that contain the words “gambling”, “porn”, or “malware” in their URLs. A URL is a uniform resource locator that identifies the location and protocol of a web resource. A URL typically consists of the following components: protocol://domain:port/path?query#fragment.The protocol specifies the communication method used to access the web resource, such as HTTP, HTTPS, FTP, or SMTP. The domain is the name of the web server that hosts the web resource, such as or The port is an optional number that identifies the specific service or application running on the web server, such as 80 for HTTP or 443 for HTTPS. The path is the specific folder or file name of the web resource, such as /index.html or /images/logo.png. The query is an optional string that contains additional information or parameters for the web resource, such as ?q=security or ?lang=en. The fragment is an optional string that identifies a specific part or section of the web resource, such as #introduction or #summary.

To prohibit access to non-encrypted websites, an analyst should employ a search string that matches the protocol of non-encrypted web traffic, which is HTTP. HTTP stands for hypertext transfer protocol, and it is a standard protocol for transferring data between web servers and web browsers. However, HTTP does not provide any encryption or security for the data, which means that anyone who intercepts the web traffic can read or modify the data. Therefore, non-encrypted websites are vulnerable to eavesdropping, tampering, or spoofing attacks. To access a non-encrypted website, the URL usually starts with followed by the domain name and optionally the port number. For example, or By scanning the URL for the string the web filter can identify and block non-encrypted websites.

The other options are not correct because they do not match the protocol of non-encrypted web traffic. Encryption=off is a possible query string that indicates the encryption status of the web resource, but it is not a standard or mandatory parameter. Https:// is the protocol of encrypted web traffic, which uses hypertext transfer protocol secure (HTTPS) to provide encryption and security for the data. Www.*.com is a possible domain name that matches any website that starts with www and ends with .com, but it does not specify the protocol. :443 is the port number of HTTPS, which is the protocol of encrypted web traffic. References = CompTIA Security+ Study Guide (SY0-701), Chapter 2: Securing Networks, page 69. Professor Messer’s CompTIA SY0-701 Security+ Training Course, Section 2.1: Network Devices and Technologies, video: Web Filter (5:16).

A tabletop exercise is a discussion-based simulation in which stakeholders review and talk through their roles, responsibilities, and actions in response to a hypothetical incident. This allows participants to evaluate and improve response plans without actual disruption.

A data retention policy is a set of rules that defines how long data should be stored and when it should be deleted or archived. An administrator assists the legal and compliance team with ensuring information about customer transactions is archived for the proper time period by following the data retention policy of the organization. This policy helps the organization to comply with legal and regulatory requirements, optimize storage space, and protect data privacy and security.

Allowing risky protocols like SMB and RDP from the internet to a controlled VLAN is commonly done to create a honeynet, a deliberately vulnerable network environment used to attract attackers and study their behaviors without risking production systems.

Building a file-sharing site (A) or preparing for a pentest (B) typically wouldn't require exposing SMB and RDP broadly. SASE integration (C) focuses on cloud security access and doesn't involve opening such protocols indiscriminately.

Honeynets are described as a deception technology in the Security Architecture domain【6:Chapter 9†CompTIA Security+ Study Guide】.

 Capacity planning is the process of determining the resources needed to meet the current and future demands of an organization. Capacity planning can help a company develop a business continuity strategy by estimating how many staff members would be required to sustain the business in the case of a disruption, such as a natural disaster, a cyberattack, or a pandemic. Capacity planning can also help a company optimize the use of its resources, reduce costs, and improve performance. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 4, page 184.

The chmod command is used to change file permissions on Unix and Linux systems. If the /etc/shadow file has permissions beyond the baseline recommendation, the systems administrator should use chmod to modify the file's permissions, ensuring it adheres to the security baseline and limits access to authorized users only.

An insider threat is a security risk that originates from within the organization, such as an employee, contractor, or business partner, who has authorized access to the organization’s data and systems. An insider threat can be malicious, such as stealing, leaking, or sabotaging sensitive data, or unintentional, such as falling victim to phishing or social engineering. An insider threat can cause significant damage to the organization’s reputation, finances, operations, and legal compliance. The user’s activity of logging in remotely after hours and copying large amounts of data to a personal device is an example of a malicious insider threat, as it violates the organization’s security policies and compromises the confidentiality and integrity of the data. References = Insider Threats – CompTIA Security+ SY0-701: 3.2, video at 0:00; CompTIA Security+ SY0-701 Certification Study Guide, page 133.

Detailed Explanation:Privileged access management (PAM) solutions effectively mitigate pass-the-hash attacks by enforcing least privilege and session management for administrative accounts. These tools restrict how and when credentials can be accessed, thereby reducing attack surfaces.

Job rotation is a strategy used in organizations to detect and prevent fraud by periodically assigning employees to different roles within the organization. This approach helps ensure that no single employee has exclusive control over a specific process or set of tasks for an extended period, thereby reducing the opportunity for fraudulent activities to go unnoticed. By rotating roles, organizations can uncover irregularities and discrepancies that might have been concealed by an employee who had prolonged access to sensitive functions. Job rotation also promotes cross-training, which can enhance the organization's overall resilience and flexibility.

Risk appetiterefers to thelevel of risk an organization is willing to acceptbefore implementing security measures. When expanding access controls, the company must assess how much risk is acceptable in terms ofdata exposure, unauthorized access, and compliance obligations.

Port security is the best mitigation technique for preventing an attacker from flooding the MAC address table of network switches. Port security can limit the number of MAC addresses learned on a port, preventing an attacker from overwhelming the switch's MAC table (a form of MAC flooding attack). When the allowed number of MAC addresses is exceeded, port security can block additional devices or trigger alerts.

Load balancer distributes network traffic but does not address MAC flooding attacks.

IPS (Intrusion Prevention System) detects and prevents attacks but isn't specifically designed for MAC flooding mitigation.

NGFW (Next-Generation Firewall) offers advanced traffic inspection but is not directly involved in MAC table security​​​.

Risk threshold is the maximum amount of risk that an organization is willing to accept for a given activity or decision. It is also known as risk appetite or risk tolerance. Risk threshold helps an organization to prioritize and allocate resources for risk management. Risk indicator, risk level, and risk score are different ways of measuring or expressing the likelihood and impact of a risk, but they do not describe the maximum allowance of accepted risk. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 34; Accepting Risk: Definition, How It Works, and Alternatives

Integrating each SaaS solution with an Identity Provider (IdP) is the most effective way to address the security issue. This approach allows for Single Sign-On (SSO) capabilities, where users can access multiple SaaS applications with a single set of credentials while maintaining strong password policies across all services. It simplifies the user experience and ensures consistent security enforcement across different SaaS platforms.

Using a Privileged Access Management (PAM) vault to secure domain administrator credentials and enforcing role-based access control (RBAC) is the most comprehensive solution. PAM systems help manage and control access to privileged accounts, ensuring that only authorized personnel can access sensitive credentials. This approach also facilitates password rotation, auditing, and ensures that credentials are not misused or left unchanged. Integrating PAM with RBAC ensures that access is granted based on the user's role, further enhancing security.

AES-256 is a symmetric encryption algorithm widely used to protect data at rest by converting plaintext into ciphertext that is unreadable without the proper key. It provides strong confidentiality and is a standard for encrypting stored data.

TLS 1.2 (A) secures data in transit, not at rest. Masking (C) obscures data but typically for display or limited use and is reversible. Salting (D) is used alongside hashing to protect passwords and data integrity but does not encrypt data.

Encryption with AES-256 is recognized as a best practice for securing stored data in the Security+ Cryptography and General Security Concepts domains【6:Chapter 7†CompTIA Security+ Study Guide】.

= A jump server is a server that acts as an intermediary between a user and a target system. A jump server can provide an added layer of security by preventing unauthorized access to internal company resources. A user can connect to the jump server using a secure protocol, such as SSH, and then access the target system from the jump server. This way, the target system is isolated from the external network and only accessible through the jump server. A jump server can also enforce security policies, such as authentication, authorization, logging, and auditing, on the user’s connection. A jump server is also known as a bastion host or a jump box. References = CompTIA Security+ Certification Exam Objectives, Domain 3.3: Given a scenario, implement secure network architecture concepts. CompTIA Security+ Study Guide (SY0-701), Chapter 3: Network Architecture and Design, page 101. Other Network Appliances – SY0-601 CompTIA Security+ : 3.3, Video 3:03. CompTIA Security+ Certification Exam SY0-701 Practice Test 1, Question 2.

Management review is a critical step in the change management process. Before implementing any design change, management reviews help evaluate the potential impact, security implications, and alignment with organizational goals and policies. This review ensures that the change is justified, risks are understood, and proper approvals are obtained.

Load testing is a performance test, maintenance notifications are communication steps, and procedure updates are documentation activities — all important but generally occur after management has approved the change.

The significance of management involvement in change governance is a foundational concept in the Security Program Management and Oversight domain of the SY0-701 exam【6:Chapter 16†CompTIA Security+ Study Guide】.

A bug bounty is a program that rewards security researchers for finding and reporting vulnerabilities in an application or system. Bug bounties are often used by companies to improve their security posture and incentivize ethical hacking. A bug bounty program typically defines the scope, rules, and compensation for the researchers. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 1, page 10.

Full packet capture is a technique that records all network traffic passing through a device, such as a router or firewall. It allows for detailed analysis and investigation of network events, such as SQLi attacks, by providing the complete content and context of the packets. Full packet capture can help identify the source, destination, payload, and timing of an SQLi attack, as well as the impact on the server and database. Logging NetFlow traffic, network traffic sensors, and endpoint and OS-specific security logs can provide some information about network activity, but they do not capture the full content of the packets, which may limit the scope and depth of the investigation. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 372-373

Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into a website, which are then executed in the user’s web browser, potentially leading to data theft or session hijacking.References: Security+ SY0-701 Course Content​, Security+ SY0-601 Book​.

Full Disk Encryption (FDE) ensures that all data on the drive is encrypted, preventing unauthorized access even if the device is lost.

Memory injectionoccurs whenmalicious code is written into the memory space of a running process, allowing it to execute without writing anything to disk. This is often used infileless malware attacks, making detection harder.

A (privilege escalation)describes a race condition, not memory injection.

B (unexpected data causing execution)describes abuffer overflow attack, not memory injection.

D (overwriting an executable)is apersistence technique, but it is not an example of in-memory injection.

Multicloud architectures involve distributing workloads across multiple Infrastructure as a Service (IaaS) providers to improve resilience, reduce vendor lock-in, and increase fault tolerance.

SaaS diversity (B) relates to software services, load balancing (C) typically applies to on-premises, and off-site locations (D) are physical backups.

Full disk encryption (A)ensures that data stored on the device is protected even if the device is physically stolen. This is a fundamental security control for end-user devices, especially laptops and mobile devices, to prevent data breaches.

Endpoint protection (D)refers to anti-malware, antivirus, and host-based firewall solutions that safeguard end-user devices from malware, ransomware, and unauthorized access.

Jailbreaking is a primary security concern for a company setting up a BYOD (Bring Your Own Device) program. Jailbreaking is the process of removing the manufacturer’s or the carrier’s restrictions on a device, such as a smartphone or a tablet, to gain root access and install unauthorized or custom software. Jailbreaking can compromise the security of the device and the data stored on it, as well as expose it to malware, viruses, or hacking. Jailbreaking can also violate the warranty and the terms of service of the device, and make it incompatible with the company’s security policies and standards. Therefore, a company setting up a BYOD program should prohibit jailbreaking and enforce device compliance and encryption. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 2, page 76.

Daily vulnerability scans help identify missing patches or updates across endpoints, allowing security teams to ensure compliance with patch management policies. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Vulnerability Management"​​.

A reflected denial of service (RDoS) attack is a type of DDoS attack that uses spoofed source IP addresses to send requests to a third-party server, which then sends responses to the victim server. The attacker exploits the difference in size between the request and the response, which can amplify the amount of traffic sent to the victim server. The attacker also hides their identity by using the victim’s IP address as the source. A RDoS attack can target DNS servers by sending forged DNS queries that generate large DNS responses. This can flood the network interface of the DNS server and prevent it from serving legitimate requests from end users. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 215-216 1

Ransomware is a type of malware that encrypts the victim’s files and demands a ransom for the decryption key. The ransomware usually displays a message on the infected system with instructions on how to pay the ransom and recover the files. The .ryk extension is associated with a ransomware variant called Ryuk, which targets large organizations and demands high ransoms1.

Changing the default password for the local administrator account on a VPN appliance is a basic security measure that would have most likely prevented the unexpected login to the remote management interface. Default passwords are often easy to guess or publicly available, and attackers can use them to gain unauthorized access to devices and systems. Changing the default password to a strong and unique one reduces the risk of brute-force attacks and credential theft. Using least privilege, assigning individual user IDs, and reviewing logs more frequently are also good security practices, but they are not as effective as changing the default password in preventing the unexpected login. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 116; Local Admin Accounts - Security Risks and Best Practices (Part 1)

 A honey pot is a system or a network that is designed to mimic a real production server and attract potential attackers. A honey pot can be used to identify the attacker’s methods, techniques, and objectives without affecting the actual production servers. A honey pot can also divert the attacker’s attention from the real targets and waste their time and resources12.

The other options are not effective ways to identify potential attacker activities without affecting production servers:

Video surveillance: This is a physical security technique that uses cameras and monitors to record and observe the activities in a certain area. Video surveillance can help to deter, detect, and investigate physical intrusions, but it does not directly identify the attacker’s activities on the network or the servers3.

Zero Trust: This is a security strategy that assumes that no user, device, or network is trustworthy by default and requires strict verification and validation for every request and transaction. Zero Trust can help to improve the security posture and reduce the attack surface of an organization, but it does not directly identify the attacker’s activities on the network or the servers4.

Geofencing: This is a security technique that uses geographic location as a criterion to restrict or allow access to data or resources. Geofencing can help to protect the data sovereignty andcompliance of an organization, but it does not directly identify the attacker’s activities on the network or the servers5.

Attestation refers to providing formal evidence or proof that a particular process or activity has been completed according to standards or requirements. In this context, attestation involves demonstrating to customers or stakeholders that software developers have received appropriate training on secure coding practices.

Assurance generally refers to confidence or guarantees about the security posture but does not specifically mean proving or certifying training. Due diligence is the effort made to ensure compliance or safety, but it is not the act of proving training has occurred. A contract is a legal agreement, which may include requirements for training but is not the act of proving training itself.

The importance of attestation in compliance and governance processes is discussed in the Security Program Management and Oversight domain in SY0-701 materials【7:Chapter 5†CompTIA Security+ Practice Tests】.

A tabletop exercise is a discussion-based exercise where stakeholders gather to walk through the roles and responsibilities they would have during a specific situation, such as a security incident or disaster. This type of exercise is designed to identify gaps in planning and improve coordination among team members without the need for physical execution.

References = CompTIA Security+ SY0-701 study materials, particularly in the domain of security operations and disaster recovery planning​​.

Detailed Explanation:The activity described in the table, where multiple connection attempts are made on port 445 (used for SMB services), suggests a brute-force attack. The attacker likely used automated methods to guess credentials, causing multiple failures. Such attempts are ahallmark of brute-force attacks targeting shared resources. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Indicators of Malicious Activity"​​.

A honeytoken is a form of deception technology in which a fake asset (such as credentials, files, or database records) is planted in a system or network to detect unauthorized access or malicious activity. The fake password stored in a hidden spreadsheet, with monitoring for access, is a classic example of a honeytoken. It is not an interactive system (like a honeypot or honeynet) but rather a marker or tripwire intended to alert the security team to suspicious behavior. This method helps identify attackers and their methods early in the intrusion process.

Access control lists (ACLs) are rules that specify which users or groups can access which resources on a file server. They can help restrict access to confidential data by granting or denying permissions based on the identity or role of the user. In this case, the administrator can use ACLs to quickly modify the access rights of the users and prevent them from accessing the data they are not authorized to see. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 308 1

Organized crime is a type of threat actor that is motivated by financial gain and often operates across national borders. Organized crime groups may be hired by foreign governments to conduct cyberattacks on critical systems located in other countries, such as power grids, military networks, or financial institutions. Organized crime groups have the resources, skills, and connections to carry out sophisticated and persistent attacks that can cause significant damage and disruption12. References = 1: Threat Actors - CompTIA Security+ SY0-701 - 2.1 2: CompTIA Security+ SY0-701 Certification Study Guide

The most important consideration when establishing a data privacy program is defining the organization's role as a controller or processor. These roles, as outlined in privacy regulations such as the General Data Protection Regulation (GDPR), determine the responsibilities regarding the handling of personal data. A controller is responsible for determining the purpose and means of data processing, while a processor acts on behalf of the controller. This distinction is crucial for compliance with data privacy laws.

Reporting structure for the data privacy officer is important, but it is a secondary consideration compared to legal roles.

Request process for data subject access is essential for compliance but still depends on the organization's role as controller or processor.

Physical location of the company can affect jurisdiction, but the role as controller or processor has a broader and more immediate impact​​​.

An Acceptable Use Policy (AUP) defines what users are permitted and prohibited from doing on an organization's systems, including website access. Accessing unauthorized sites is a common violation of the AUP.

Software as a Service (SaaS) represents an application that is hosted in the cloud and accessible via the internet from anywhere, with no requirement for on-premises infrastructure. SaaS applications are managed by a third-party provider, allowing users to access them through a web browser, making them highly scalable and flexible for remote access.

A full inventory of all hardware and software is essential for measuring the overall risk to an organization when a new vulnerability is disclosed, because it allows the security analyst to identify which systems are affected by the vulnerability and prioritize the remediation efforts. Without a full inventory, the security analyst may miss some vulnerable systems or waste time and resources on irrelevant ones. Documentation of system classifications, a list of system owners and their departments, and third-party risk assessment documentation are all useful for risk management, but they are not sufficient to measure the impact of a new vulnerability. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 1221; Risk Assessment and Analysis Methods: Qualitative and Quantitative3

An AI tool developed internally for automating ticketing is considered intellectual property (IP), representing proprietary creations and innovations owned by the company.

Classified (A) applies to government or restricted information, regulated information (B) refers to data governed by laws, and open source (C) implies publicly shared code.

IP protection is a key aspect of Security Program Management, especially around proprietary software and tools【6:Chapter 16†CompTIA Security+ Study Guide】.

Change management procedures provide structured steps to approve, test, document, and deploy software changes, ensuring controlled and auditable version releases that minimize risks and disruptions.

Business continuity planning (A) relates to operational continuity, quantified risk analysis (B) assesses risks quantitatively, and static code analysis (C) finds coding defects but does not control release processes.

Change management is fundamental to software lifecycle governance in SY0-701【6:Chapter 16†CompTIA Security+ Study Guide】.

=================

Phishing is a type of social engineering attack that involves sending fraudulent emails that appear to be from legitimate sources, such as payment websites, banks, or other trusted entities. The goal of phishing is to trick the recipients into clicking on malicious links, opening malicious attachments, or providing sensitive information, such as log-in credentials, personal data, or financial details. In this scenario, the employee received an email from a payment website that asked the employee to update contact information. The email contained a link that directed the employee to a fake website that mimicked the appearance of the real one. The employee entered the log-in information, but received a “page not found” error message. This indicates that the employee fell victim to a phishing attack, and the attacker may have captured the employee’s credentials for the payment website. References = Other Social Engineering Attacks – CompTIA Security+ SY0-701 – 2.2, CompTIA Security+: Social Engineering Techniques & Other Attack … - NICCS, [CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition]

Badge access and access control vestibule are two of the best ways to ensure only authorized personnel can access a secure facility. Badge access requires the personnel to present a valid and authenticated badge to a reader or scanner that grants or denies access based on predefined rules and permissions. Access control vestibule is a physical security measure that consists of a small room or chamber with two doors, one leading to the outside and one leading to the secure area. The personnel must enter the vestibule and wait for the first door to close and lock before the second door can be opened. This prevents tailgating or piggybacking by unauthorized individuals. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 4, pages 197-1981

A Host-based Intrusion Prevention System (HIPS) protects individual devices by monitoring and preventing malicious activity directly on the host. It is ideal for protecting traveling employees’ devices outside the corporate network.

Isolation (A) and segmentation (B) apply to networks, and ACL (Access Control List) (C) restricts network traffic but does not provide host-level protection.

HIPS is emphasized in Security Operations for endpoint protection【6:Chapter 11†CompTIA Security+ Study Guide】.

A Secure Web Gateway (SWG) protects users by filtering unwanted software/malware from user-initiated web traffic and enforcing corporate and regulatory policy compliance. This technology allows the company to secure remote users' data and web traffic without relying on a VPN, making it ideal for organizations supporting remote work.

Zero-day vulnerabilities are unknown flaws in software, making them harder to patch, especially when using open-source libraries without dedicated support teams.

=================

Encryption is a method of transforming data in a way that makes it unreadable without a secret key necessary to decrypt the data back into plaintext. Encryption is one of the most common and effective ways to protect data at rest, as it prevents unauthorized access, modification, or theft of the data. Encryption can be applied to different types of data at rest, such as block storage, object storage, databases, archives, and so on. Hashing, tokenization, and segmentation are not methods of rendering data at rest unreadable, but rather of protecting data in other ways. Hashing is a one-way function that generates a fixed-length output, called a hash or digest, from an input, such that the input cannot be recovered from the output. Hashing is used to verify the integrity and authenticity of data, but not to encrypt it. Tokenization is a process that replaces sensitive data with non-sensitive substitutes, called tokens, that have no meaning or value on their own. Tokenization is used to reduce the exposure and compliance scope of sensitive data, but not to encrypt it. Segmentation is a technique that divides a network or a system into smaller, isolated units, called segments, that have different levels of access and security. Segmentation is used to limit the attack surface and contain the impact of a breach, but not to encrypt data at rest. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, pages 77-781; Protecting data at rest - Security Pillar3

Endpoint detection and response (EDR) is a technology that monitors and analyzes the activity and behavior of endpoints, such as computers, laptops, mobile devices, and servers. EDR can help to detect and prevent malicious software, such as viruses, malware, and Trojans, from infecting the endpoints and spreading across the network. EDR can also provide visibility and response capabilities to contain and remediate threats. EDR is different from IDS, which is a network-based technology that monitors and alerts on network traffic anomalies. EDR is also different from ACL, which is a list of rules that control the access to network resources. EDR is also different from NAC, which is a technology that enforces policies on the network access of devices based on their identity and compliance status. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 2561

RBAC stands for Role-Based Access Control, which is a method of restricting access to data and resources based on the roles or responsibilities of users. RBAC simplifies the management of permissions by assigning roles to users and granting access rights to roles, rather than to individual users. RBAC can help enforce the principle of least privilege and reduce the risk of unauthorized access or data leakage. The other options are not as suitable for the scenario asRBAC, as they either do not prevent access based on responsibilities, or do not apply a simplified format. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 133 1

Orchestration is the process of automating multiple tasks across different systems and applications. It can help save time and reduce human error by executing predefined workflows and scripts. In this case, the systems administrator can use orchestration to create accounts for a large number of end users without having to manually enter their information and assign permissions. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 457 1

Containers are a method of virtualization that allows applications to run in isolated environments with their own dependencies, libraries, and configurations. Containers are best suited for constantly changing environments because they are lightweight, portable, scalable, and easy to deploy and update. Containers can also support microservices architectures, which enable faster and more frequent delivery of software features. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 10: Mobile Device Security, page 512 1

Smishing is a type of social engineering technique that uses text messages (SMS) to trick victims into revealing sensitive information, clicking malicious links, or downloading malware. Smishing messages often appear to come from legitimate sources, such as banks, government agencies, or service providers, and use urgent or threatening language to persuade the recipients to take action12. In this scenario, the text message that claims to be from the payroll department is an example of smishing.

Impersonation is a type of social engineering technique that involves pretending to be someone else, such as an authority figure, a trusted person, or a colleague, to gain the trust or cooperation of the target. Impersonation can be done through various channels, such as phone calls, emails, text messages, or in-person visits, and can be used to obtain information, access, or money from the victim34. In this scenario, the text message that pretends to be from the payroll department is an example of impersonation.

A. Typosquatting is a type of cyberattack that involves registering domain names that are similar to popular or well-known websites, but with intentional spelling errors or different extensions. Typosquatting aims to exploit the common mistakes that users make when typingweb addresses, and redirect them to malicious or fraudulent sites that may steal their information, install malware, or display ads56. Typosquatting is not related to text messages or credential verification.

B. Phishing is a type of social engineering technique that uses fraudulent emails to trick recipients into revealing sensitive information, clicking malicious links, or downloading malware. Phishing emails often mimic the appearance and tone of legitimate organizations, such as banks, retailers, or service providers, and use deceptive or urgent language to persuade the recipients to take action78. Phishing is not related to text messages or credential verification.

D. Vishing is a type of social engineering technique that uses voice calls to trick victims into revealing sensitive information, such as passwords, credit card numbers, or bank account details. Vishing calls often appear to come from legitimate sources, such as law enforcement, government agencies, or technical support, and use scare tactics or false promises to persuade the recipients to comply9 . Vishing is not related to text messages or credential verification.

F. Misinformation is a type of social engineering technique that involves spreading false or misleading information to influence the beliefs, opinions, or actions of the target. Misinformation can be used to manipulate public perception, create confusion, damage reputation, or promote an agenda . Misinformation is not related to text messages or credential verification.

 Root cause analysis is a process of identifying and resolving the underlying factors that led to an incident. By conducting root cause analysis as part of incident response, security professionals can learn from the incident and implement corrective actions to prevent future incidents of the same nature. For example, if the root cause of a data breach was a weak password policy, the security team can enforce a stronger password policy and educate users on the importance of password security. Root cause analysis can also help to improve security processes, policies, and procedures, and to enhance security awareness and culture within the organization. Root cause analysis is not meant to gather loCs (indicators of compromise) for the investigation, as this is a task performed during the identification and analysis phases of incident response. Root cause analysis is also not meant to discover which systems have been affected or to eradicate any trace of malware on the network, as these are tasks performed during the containment and eradicationphases of incident response. References = CompTIA Security+ SY0-701 Certification Study Guide, page 424-425; Professor Messer’s CompTIA SY0-701 Security+ Training Course, video 5.1 - Incident Response, 9:55 - 11:18.

If cadets are using company phone numbers to make unsolicited calls, and the logs confirm the numbers are not being spoofed, it suggests that the SIP (Session Initiation Protocol) server's security settings might be weak. This could allow unauthorized access or exploitation of the company's telephony services, potentially leading to misuse by unauthorized individuals.

Validating the code signature is the best way to verify software authenticity, as it ensures that the software has not been tampered with and that it comes from a verified source. Code signatures are digital signatures applied by the software vendor, and validating them confirms the software's integrity and origin.References: CompTIA Security+ SY0-701 course content and official CompTIA study resources.

A tabletop exercise is a simulation-based activity where incident response team members and relevant stakeholders walk through a hypothetical security incident in a discussion-based format. This exercise helps validate response plans, roles, and communication channels without actual system disruption.

Lessons learned (A) is a post-incident review, digital forensics (B) is evidence collection after an incident, and root cause analysis (D) investigates the underlying cause after an event.

Tabletop exercises are standard practices within the Security Operations domain to prepare teams for real incidents【6:Chapter 14†CompTIA Security+ Study Guide】.

Zero Trust architecture is based on the principle of "never trust, always verify," meaning all traffic between systems must be authenticated and authorized before communication is allowed, regardless of network location.

Policy enforcement (A) is important but broader. Authentication (B) is a component of Zero Trust, and confidentiality (D) refers to data protection, not access validation.

Zero Trust is a modern security framework emphasized in Security Architecture for securing enterprise environments【6:Chapter 3†CompTIA Security+ Study Guide】.

A content filter is a device or software that blocks or allows access to web content based on predefined rules or categories. In this case, the new retail website is mistakenly categorized as gambling by the content filter, which prevents users from accessing it. To resolve this issue, the content filter’s categorization needs to be updated to reflect the correct category of the website, such as shopping or retail. This will allow the content filter to allow access to the website instead of blocking it.

Injecting malicious payloads into a hypervisor and accessing the host system is an example of VM escape, where the isolation between virtual machines and the host breaks down, allowing unauthorized control.

Cross-site scripting (B), malicious updates (C), and SQL injection (D) are unrelated to hypervisor host access.

VM escape is a critical vulnerability unique to virtualized environments described in SY0-701【6:Chapter 2†CompTIA Security+ Study Guide】.

Automated vulnerability scanningis thefirst step in identifying system weaknesses. These scans systematically check for outdated software, misconfigurations, and known vulnerabilities in a network.

Penetration testing (B)is conducted after vulnerabilities are identified.

Threat hunting (C)focuses on detecting unknown threats, not listing vulnerabilities.

Detailed Explanation:A VM escape occurs when an attacker breaks out of a virtual machine's isolation to access the hypervisor. This compromise can allow control of the hypervisor and all other VMs on the host, posing significant security risks. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 3: Security Architecture, Section: "Virtualization Risks and Mitigation"​​.

An application allow list is a security technique that specifies which applications are permitted to run on a system or a network. An application allow list can block unknown programs from executing by only allowing the execution of programs that are explicitly authorized and verified. An application allow list can prevent malware, unauthorized software, or unwanted applications from running and compromising the security of the system or the network12.

The other options are not the best ways to block unknown programs from executing:

Access control list: This is a security technique that specifies which users or groups are granted or denied access to a resource or an object. An access control list can control the permissions and privileges of users or groups, but it does not directly block unknown programs from executing13.

Host-based firewall: This is a security device that monitors and filters the incoming and outgoing network traffic on a single host or system. A host-based firewall can block or allow networkconnections based on predefined rules, but it does not directly block unknown programs from executing1 .

DLP solution: This is a security system that detects and prevents the unauthorized transmission or leakage of sensitive data. A DLP solution can protect the confidentiality and integrity of data, but it does not directly block unknown programs from executing1 .

According to the CompTIA Security+ SY0-701 Certification Study Guide, data subjects are the individuals whose personal data is collected, processed, or stored by an organization. Data subjects have certain rights and expectations regarding how their data is handled, such as the right to access, correct, delete, or restrict their data. Data subjects are different from data owners, who are the individuals or entities that have the authority and responsibility to determine how data is classified, protected, and used. Data subjects are also different from data processors, who are the individuals or entities that perform operations on data on behalf of the data owner, such as collecting, modifying, storing, or transmitting data. Data subjects are also different from data custodians, who are the individuals or entities that implement the security controls and procedures specified by the data owner to protect data while in transit and at rest.

Intellectual property is a type of data that consists of ideas, inventions, designs, or other creative works that have commercial value and are protected by law. Employees in the research and development business unit are most likely to use intellectual property data in their day-to-day work activities, as they are involved in creating new products or services for the company. Intellectual property data needs to be protected from unauthorized use, disclosure, or theft, as it can give the company a competitive advantage in the market. Therefore, these employees receive extensive training to ensure they understand how to best protect this type of data. References = CompTIA Security+ SY0-701 Certification Study Guide, page 90; Professor Messer’s CompTIA SY0-701 Security+ Training Course, video 1.2 - Security Concepts, 7:57 - 9:03.

Detailed Explanation:The acquisition phase involves creating forensic images (exact replicas) of storage devices or memory to ensure data integrity for further analysis. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 4: Security Operations, Section: "Forensic Imaging and Chain of Custody"​​.

Detailed Explanation:Quarantining a potentially infected system by placing it into an air-gapped environment physically disconnects it from the network. This prevents the spread of malware while maintaining the integrity of forensic evidence.

Data classification is required before implementing a Data Loss Prevention (DLP) solution because DLP policies depend on identifying and categorizing sensitive data to monitor, block, or encrypt it accordingly.

Data destruction (A) and sanitization (B) remove data, and masking (D) obscures data but classification is foundational for DLP effectiveness.

Data classification is emphasized in Security Program Management and Data Protection topics【6:Chapter 16†CompTIA Security+ Study Guide】.

A VPN is a virtual private network that creates a secure tunnel between two or more devices over a public network. A VPN can encrypt and authenticate the data, as well as hide the IP addresses and locations of the devices. A jump server is a server that acts as an intermediary between a user and a target server, such as a production server. A jump server can provide an additional layer of security and access control, as well as logging and auditing capabilities. A firewall is a device or software that filters and blocks unwanted network traffic based on predefined rules. A firewall can protect the internal network from external threats and limit the exposure of sensitive services and ports. A security analyst should recommend setting up a VPN and placing the jump server inside the firewall to improve the security of the remote desktop access to the production network. This way, the remote desktop service will not be exposed to the public network, and only authorized users with VPN credentials can access the jump server and then the production server. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 8: Secure Protocols and Services, page 382-383 1; Chapter 9: Network Security, page 441-442 1

Hashing (C)is aone-way cryptographic functionthat produces afixed-length digestrepresenting the original data. If the file changes—even by one bit—the hash will change, making it ideal for verifyingdata integrity.

While encryption protectsconfidentiality, and masking/obfuscation protectdata visibility, onlyhashing ensures integrity.

A Host-based Intrusion Prevention System (HIPS) acts as a preventive control by actively blocking threats and a detective control by monitoring and alerting to suspicious activities on endpoints.

Situational awareness refers to being mindful of security risks in one's environment and taking proactive measures to mitigate them. In this scenario, employees are failing to display their identification badges and allowing unauthorized personnel to follow them into restricted areas (tailgating). These behaviors pose significant security risks, such as unauthorized access to sensitive locations.

Security training focused on situational awareness will educate employees on the importance of remaining vigilant about security practices, recognizing potential threats, and enforcing access control measures.

Social engineering involves manipulating individuals to gain unauthorized access, but this scenario highlights poor adherence to security protocols rather than deception.

Phishing is an email-based attack aimed at stealing sensitive information, which is unrelated to physical security lapses.

Acceptable use policy governs the proper use of company resources but does not specifically address tailgating or badge display issues.

Thus, situational awareness is the most relevant security training topic for addressing these concerns.

Tokenization is a process that replaces sensitive data, such as credit card information, with a non-sensitive equivalent (token) that can be used in place of the actual data. This technique is particularly useful in securely storing payment information because the token can be safely stored and transmitted without exposing the original credit card number.

A regulatory requirement is a mandate imposed by a government or an authority that must be followed by an organization or an individual. In a banking environment, audits are often required by regulators to ensure compliance with laws, standards, and policies related to security, privacy, and financial reporting. Audits help to identify and correct any gaps or weaknesses in the security posture and the internal controls of the organization.

E-discovery (electronic discovery) is the process of identifying, collecting, and producing electronically stored information (ESI) in response to a legal request or investigation. It is a critical component of digital forensics when dealing with litigation, compliance, or regulatory matters.

To identify the exactcommand or input usedduring a SQL injection attack, theapplication log (B)is the most relevant. It records inputs, errors, and processing activities within the application layer.

UnderDomain 2.1, CompTIA emphasizes reviewingapplication logsto detect indicators of malicious activity, includingweb application attackslike SQL injection.

Port security is the best solution to prevent unauthorized devices, like a visitor's laptop, from connecting to the company’s network. Port security can limit the number of devices that can connect to a network switch port and block unauthorized MAC addresses, effectively stopping unauthorized access attempts.

Web application firewall (WAF) protects against web-based attacks, not unauthorized network access.

Transport Layer Security (TLS) ensures encrypted communication but does not manage physical network access.

Virtual Private Network (VPN) secures remote connections but does not control access through physical network ports​​​.

Failure to comply with right-to-be-forgotten (data privacy) regulations can lead to significant fines imposed by regulatory authorities like GDPR enforcers. Such laws require companies to delete personal data upon user request.

Data breaches (B) are security incidents; revenue loss (C) and blackmail (D) may occur indirectly but fines are the direct legal consequence.

Regulatory compliance and consequences are critical topics in Security Program Management【6:Chapter 16†CompTIA Security+ Study Guide】

Adding a random string of characters, known as a "salt," to a password before hashing it is known as salting. This technique strengthens passwords by ensuring that even if two users have the same password, their hashes will be different due to the unique salt, making it much harder for attackers to crack passwords using precomputed tables.References: CompTIA Security+ SY0-701 course content and official CompTIA study resources.

Key escrow is a method of storing encryption keys in a secure location, such as a trusted third party or a hardware security module (HSM). Key escrow is important for FDE because it allows the recovery of encrypted data in case of lost or forgotten passwords, device theft, or hardware failure. Key escrow also enables authorized access to encrypted data for legal or forensic purposes.

TPM presence is a feature of some laptops that have a dedicated chip for storing encryption keys and other security information. TPM presence is important for FDE because it enhances the security and performance of encryption by generating and protecting the keys within the chip, rather than relying on software or external devices. TPM presence also enables features such as secure boot, remote attestation, and device authentication. 

A serverless framework is a cloud-based application-hosting solution that meets the requirements of low-cost and cloud-based. A serverless framework is a type of cloud computing service that allows developers to run applications without managing or provisioning any servers. The cloud provider handles the server-side infrastructure, such as scaling, load balancing, security, and maintenance, and charges the developer only for the resources consumed by the application. A serverless framework enables developers to focus on the application logic and functionality, and reduces the operational costs and complexity of hosting applications. Some examples of serverless frameworks are AWS Lambda, Azure Functions, and Google Cloud Functions.

A type 1 hypervisor, SD-WAN, and SDN are not cloud-based application-hosting solutions that meet the requirements of low-cost and cloud-based. A type 1 hypervisor is a software layer that runs directly on the hardware and creates multiple virtual machines that can run different operating systems and applications. A type 1 hypervisor is not a cloud-based service, but a virtualization technology that can be used to create private or hybrid clouds. A type 1 hypervisor also requires the developer to manage and provision the servers and the virtual machines, which can increase the operational costs and complexity of hosting applications. Some examples of type 1 hypervisors are VMware ESXi, Microsoft Hyper-V, and Citrix XenServer.

SD-WAN (Software-Defined Wide Area Network) is a network architecture that uses software to dynamically route traffic across multiple WAN connections, such as broadband, LTE, or MPLS. SD-WAN is not a cloud-based service, but a network optimization technology that can improve the performance, reliability, and security of WAN connections. SD-WAN can be used to connect remote sites or users to cloud-based applications, but it does not host the applications itself. Some examples of SD-WAN vendors are Cisco, VMware, and Fortinet.

SDN (Software-Defined Networking) is a network architecture that decouples the control plane from the data plane, and uses a centralized controller to programmatically manage and configure the network devices and traffic flows. SDN is not a cloud-based service, but a network automation technology that can enhance the scalability, flexibility, and efficiency of the network. SDN can be used to create virtual networks or network functions that can support cloud-based applications, but it does not host the applications itself. Some examples of SDN vendors are OpenFlow, OpenDaylight, and OpenStack.

Baseline configuration is the process of standardizing the configuration settings for a system or network. In this scenario, the organization needs to standardize the operating system configurations before deploying them across the network. Establishing a baseline configuration ensures that all systems adhere to the organization's security policies and operational requirements.

The Online Certificate Status Protocol (OCSP) is a technology designed to check the revocation status of digital certificates in real-time without requiring the client to download entire revocation lists. Unlike Certificate Revocation Lists (CRLs), which are periodically updated and can be large, OCSP queries an OCSP responder to receive the status of a specific certificate.

OCSP is considered passive verification because it allows clients to check a certificate's current validity status on-demand without maintaining local copies of revocation data. The OCSP responder returns whether the certificate is valid, revoked, or expired.

Trusted Platform Module (TPM) is hardware for secure key storage, and Certificate Signing Request (CSR) is a request for certificate issuance; neither is used for verifying certificate expiration status.

The differences and roles of OCSP and CRLs are thoroughly covered in the Cryptography and PKI chapter of the SY0-701, where OCSP is highlighted as the more efficient and real-time method to verify certificate status passively【6:Chapter 7†CompTIA Security+ Study Guide】.

The most likely way a rogue device was able to connect to the network is through a MAC cloning attack. In this attack, a personal device copies the MAC address of an authorized device, bypassing the 802.1X access control that relies on known hardware addresses for network access. The matching MAC addresses in the audit report suggest that this technique was used to gain unauthorized network access.

Salting is the process of adding extra random data to a password or other data before applying a one-way data transformation algorithm, such as a hash function. Salting increases the complexity and randomness of the input data, making it harder for attackers to guess or crack the original data using precomputed tables or brute force methods. Salting also helps prevent identicalpasswords from producing identical hash values, which could reveal the passwords to attackers who have access to the hashed data. Salting is commonly used to protect passwords stored in databases or transmitted over networks. References =

A honeypot is a security mechanism set up to attract and detect potential attackers by simulating vulnerable assets. By hosting a part of the infrastructure online with known vulnerabilities that appear to be company assets, the company can observe and analyze the behavior of attackersconducting reconnaissance. This approach allows the company to get alerts and gather intelligence on potential threats.

A warm site is the best option for a business that does not require immediate failover but wants to reduce the workload required for recovery. A warm site has some pre-installed equipment and data, allowing for quicker recovery than a cold site, but it still requires some setup before becoming fully operational.

Hot sites provide immediate failover but are more expensive and require constant maintenance.

Cold sites require significant time and effort to get up and running after an outage.

Geographically dispersed sites refer to a specific location strategy rather than the readiness of the recovery site​​.
