Free and Premium PECB ISO-IEC-27002-Foundation Dumps Questions Answers

Information security determines both what needs to be protected and how protection should be applied. The first part is understanding information assets, their value, their sensitivity, their owners, their business purpose, and the consequences if they are disclosed, altered, lost, or unavailable. This answers what must be protected and why. The second part is understanding threats, vulnerabilities, risk levels, legal obligations, contractual duties, and control options. This answers what the information must be protected from and how security controls should be designed. ISO/IEC 27002 supports both dimensions. Asset inventory and classification clarify protection needs. Access control, cryptography, backup, logging, network security, secure development, incident management, and physical security define protection methods. Option A is correct but incomplete. Option B is also correct but incomplete. Option C is therefore the verified answer because information security is a complete discipline covering asset understanding, risk understanding, control selection, implementation, monitoring, and improvement. The ISO/IEC 27002 control set is structured to support that full protection lifecycle. References/Chapters: ISO/IEC 27002:2022, Control 5.9 Inventory of information and other associated assets; Control 5.12 Classification of information; Controls 5–8.

Control 6.1 Screening is the ISO/IEC 27002 control that helps organizations ensure employees and contractors are suitable for their roles. Screening is performed before employment or engagement, and it should be proportionate to business requirements, information classification, access levels, legal requirements, and the risks associated with the role. It may include verification of identity, qualifications, employment history, references, criminal record checks where lawful and appropriate, and professional credentials. The goal is not unnecessary intrusion; the goal is to reduce the risk that unsuitable individuals receive access to sensitive information, systems, facilities, or responsibilities. Control 6.4, Disciplinary process, deals with responding to policy violations after employment has begun. Control 6.7, Remote working, addresses security arrangements for work outside organizational premises. Neither directly verifies suitability before assigning a role. ISO/IEC 27002 treats people controls as essential because insider risk, negligence, excessive access, and role mismatch can create significant security exposure. Therefore, option A is the verified answer. References/Chapters: ISO/IEC 27002:2022, Control 6.1 Screening; Control 6.2 Terms and conditions of employment; Control 6.3 Information security awareness, education and training.

Confidentiality means that information is protected from unauthorized disclosure or availability. The correct statement is option A because it expresses the essential confidentiality concept: information must not be made available or disclosed to unauthorized individuals, entities, or processes. ISO/IEC 27002 supports confidentiality through controls such as information classification, labelling, access control, identity management, authentication, cryptography, data masking, information transfer rules, and data leakage prevention. The purpose is to ensure that only approved users, systems, or processes can view or receive information according to business need and authorization. Option B describes integrity, because accuracy and completeness relate to whether information remains correct and unaltered. Option C describes availability, because accessibility and usability on demand relate to authorized access when needed. In ISO/IEC 27002, many controls are mapped to confidentiality, integrity, and availability through control attributes. A confidentiality breach can occur through excessive internal access, accidental disclosure, lost media, weak access permissions, exposed credentials, or insecure transfer. References/Chapters: ISO/IEC 27002:2022, Clause 4 control attributes; Control 5.12 Classification of information; Control 5.15 Access control; Control 8.24 Use of cryptography.

Clock synchronization can be difficult when using multiple cloud services. ISO/IEC 27002 Control 8.17 emphasizes that clocks of information processing systems should be synchronized to approved time sources. Accurate time is essential for logging, monitoring, incident investigation, transaction integrity, forensic analysis, authentication, certificate validation, and event correlation. In a simple on-premises environment, an organization may centrally manage time sources using internal NTP servers or domain services. In multi-cloud environments, systems may span different providers, regions, platforms, managed services, containers, serverless functions, and third-party logging systems. Each environment may have different time settings, time source controls, administrative access limits, time zone handling, timestamp formats, and logging precision. This makes consistent synchronization and correlation more challenging. Option A is not the best answer because “only on-premises services” are typically easier to synchronize under a single administrative model. Option C is too broad because the question asks when synchronization can be difficult, and the ISO/IEC 27002 exam logic points to multiple cloud services. References/Chapters: ISO/IEC 27002:2022, Control 8.17 Clock synchronization; Control 8.15 Logging; Control 5.23 Information security for use of cloud services.

When using cryptography, organizations should consider roles and responsibilities for key management. Cryptographic controls are only effective when keys are properly generated, stored, distributed, rotated, backed up, revoked, destroyed, and protected from unauthorized access. Weak key management can defeat strong algorithms because compromise of the key can expose encrypted information or allow unauthorized signing, decryption, or impersonation. ISO/IEC 27002 Control 8.24, Use of cryptography, guides organizations to define rules for effective cryptographic use, including protection of confidentiality, authenticity, integrity, and non-repudiation where relevant. Key management responsibilities must be assigned clearly so that ownership, custody, approval, recovery, and emergency access are controlled. Option B relates to project security management, not cryptographic implementation specifically. Option C relates to network security and filtering, not cryptographic key governance. Cryptography requires policy decisions about algorithms, key lengths, certificate management, lifecycle handling, legal restrictions, and separation of duties. The exam’s correct answer is therefore option A because key management is a central technical and governance constraint of cryptographic protection. References/Chapters: ISO/IEC 27002:2022, Control 8.24 Use of cryptography; Control 5.15 Access control; Control 5.17 Authentication information.

==========

Control 8.28, Secure coding, is the correct control because the question focuses on software being written securely and reducing potential vulnerabilities in the code. Secure coding addresses the practices, rules, and techniques developers should use to avoid common software weaknesses. This can include input validation, output encoding, error handling, authentication handling, secure session management, memory safety, protection against injection, secure API use, cryptographic correctness, dependency management, and code review. Control 8.29, Security testing in development and acceptance, verifies whether security requirements and controls are effective, but testing occurs after or during development and does not itself define how code should be written. Control 8.26, Application security requirements, defines security requirements for applications, but secure coding is the specific implementation practice that reduces vulnerabilities during software construction. ISO/IEC 27002 treats secure development as a lifecycle discipline: requirements define what is needed, secure coding implements it safely, and testing validates it. The direct match to the exam wording is Control 8.28. References/Chapters: ISO/IEC 27002:2022, Control 8.28 Secure coding; Control 8.26 Application security requirements; Control 8.29 Security testing in development and acceptance.

ISO/IEC 27002:2022 provides guidance for selecting, implementing, and managing information security controls. It is not the certification requirements standard; that role belongs to ISO/IEC 27001. ISO/IEC 27002 supports organizations by explaining the purpose of each control, the implementation guidance, and other related information needed to apply controls appropriately. Its controls are grouped into organizational, people, physical, and technological themes. The standard is intended to be used as a reference when organizations design security measures based on their risks, business needs, legal obligations, contractual requirements, and information security objectives. Therefore, option A is correct because “guidance” is the core function of ISO/IEC 27002. Option B is incorrect because ISO/IEC 27002 does not set mandatory requirements for certification. Option C is related to risk management, but it is not the main purpose of ISO/IEC 27002; risk management guidance is more directly associated with ISO/IEC 27005. ISO/IEC 27002 guides control implementation after risk and control needs are determined. References/Chapters: ISO/IEC 27002:2022, Clause 1 Scope; Clause 4 Structure of the standard; Controls 5–8.

Under Control 5.1, information security policies should include statements that define direction, responsibilities, and policy expectations, including how exemptions and exceptions are handled. Exception handling is important because policies cannot be treated casually or bypassed informally. When an exception is necessary, it should be justified, approved, documented, time-bound where appropriate, risk-assessed, and reviewed. This preserves governance and ensures deviations do not become uncontrolled weaknesses. Option A, recovery from a data breach, is important but belongs more naturally to incident management, business continuity, and response planning rather than the general information security policy statement. Option C, procedures for using automated information systems, may be addressed in acceptable use or operational procedures, but it is not the best match for Control 5.1’s policy content. The information security policy establishes the authority and framework for topic-specific policies and procedures. It should include high-level statements on objectives, principles, responsibilities, compliance expectations, and exception management. Therefore, option B is verified. References/Chapters: ISO/IEC 27002:2022, Control 5.1 Policies for information security; Control 5.36 Compliance with policies, rules and standards for information security; Control 5.37 Documented operating procedures.

The “Act” phase is the phase in which an organization maintains and improves the information security management system. In the PDCA logic, “Plan” establishes objectives, policies, processes, risk treatment plans, and controls. “Do” implements and operates the planned processes and controls. “Check” monitors, measures, audits, and reviews performance. “Act” uses the results of checking to correct weaknesses, improve effectiveness, and adapt the ISMS to changing conditions. ISO/IEC 27002 is not itself the PDCA requirements standard, but its controls support the management system lifecycle used by ISO/IEC 27001. Examples include independent review of information security, compliance review, learning from incidents, management of vulnerabilities, and change management. These controls generate findings and lessons that feed improvement actions. “Do” is not the best answer because it focuses on implementation. “Check” is not the best answer because it evaluates performance but does not itself complete improvement. The phase that maintains and improves the ISMS is “Act.” References/Chapters: ISO/IEC 27002:2022, Control 5.35 Independent review of information security; Control 5.27 Learning from information security incidents; ISO/IEC 27001 PDCA-based management system model.

System requirements should not be the primary factor listed for locating and constructing physical premises in the ISO/IEC 27002 physical security context. When selecting and constructing premises, organizations should consider physical and environmental threats such as local topography, flood risk, earthquake exposure, weather conditions, crime levels, civil unrest, neighboring facilities, hazardous sites, and urban threats. These considerations help reduce risks to secure areas, information processing facilities, equipment, personnel, and supporting utilities. Local topography is relevant because geography can influence flooding, landslides, access routes, drainage, and natural hazards. Urban threats are relevant because location can affect exposure to crime, protests, terrorism, traffic disruption, adjacent buildings, or public access. System requirements are important in technology design and facility planning, but they are not the type of environmental or location threat consideration targeted by this question. ISO/IEC 27002 physical controls emphasize protecting premises from physical and environmental risks, not choosing location based on application or system functional requirements. Therefore, option C is verified. References/Chapters: ISO/IEC 27002:2022, Control 7.1 Physical security perimeters; Control 7.5 Protecting against physical and environmental threats; Control 7.8 Equipment siting and protection.

Confidentiality is breached when information is made available or disclosed to unauthorized individuals, entities, or processes. Option A is the correct answer because employees from all departments have access to colleagues’ personal data, even though such access should normally be restricted to authorized roles such as HR, payroll, compliance, or designated management. Internal users can still be unauthorized users when their role does not justify access. ISO/IEC 27002 addresses this through access control, access rights management, classification, privacy protection, and information access restriction. Option B is an availability issue because a department cannot access needed customer phone numbers due to equipment failure. Option C is an integrity issue because banking information was accidentally modified. The confidentiality principle is specifically about limiting disclosure and availability of information to authorized parties only. Personal data requires additional care because privacy obligations may apply, and excessive internal access can create legal, ethical, and reputational harm. The verified answer is therefore option A. References/Chapters: ISO/IEC 27002:2022, Control 5.15 Access control; Control 5.18 Access rights; Control 5.34 Privacy and protection of PII; Control 8.3 Information access restriction.

Control 5.7, Threat intelligence, belongs to the organizational control group. ISO/IEC 27002:2022 organizes controls by clauses: Clause 5 contains organizational controls, Clause 6 contains people controls, Clause 7 contains physical controls, and Clause 8 contains technological controls. Threat intelligence is classified as organizational because it supports governance, decision-making, risk awareness, planning, prioritization, and security strategy across the organization. It involves collecting, analyzing, and using information about existing or emerging threats so the organization can reduce risk and improve controls. Threat intelligence can influence vulnerability management, incident response, monitoring, supplier risk management, awareness training, security architecture, and risk treatment plans. Although threat intelligence may use technological tools, its ISO/IEC 27002 placement is organizational because its primary purpose is to guide security decisions and readiness. Option A is incorrect because technological controls are Clause 8. Option B is incorrect because people controls are Clause 6. The verified answer is option C. References/Chapters: ISO/IEC 27002:2022, Clause 5 Organizational controls; Control 5.7 Threat intelligence; Clause 4 Structure of the standard.
