Selected SY0-701 CompTIA Security+ Questions Answers

"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.
