PECB ISO 27002 ISO-IEC-27002-Foundation New Questions

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.

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.

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.
