Control 5.35, Independent review of information security, is the control intended to ensure that the organization’s approach to managing information security remains suitable, adequate, and effective. Independent reviews provide objective evaluation of whether policies, processes, controls, responsibilities, and implementation remain aligned with business needs, risks, legal requirements, and the organization’s security objectives. The review may consider governance, control design, control operation, risk treatment, compliance, incident trends, technology changes, supplier dependencies, and audit results. Control 5.4, Management responsibilities, is important because management must ensure personnel apply security according to policies and procedures, but it is not the control specifically focused on independent review. Control 5.24 concerns planning and preparation for incident management, which supports response capability but does not broadly assess the continuing suitability of the whole security approach. The phrase “suitable, adequate and effective” is a strong indicator of review and assurance. ISO/IEC 27002 uses independent review to challenge assumptions, detect weaknesses, and support continual improvement. Therefore, option B is the verified answer.

ISO/IEC 27002 requires equipment to be sited and protected in a way that reduces risks from physical and environmental threats. These threats include fire, flood, dust, vibration, electrical interference, unauthorized access, power instability, temperature extremes, and other environmental hazards. Option A is correct because secure siting and protection of equipment are essential to preserving confidentiality, integrity, and availability of information processing facilities. Option B is incorrect because equipment can absolutely be affected by power failures, utility disruptions, voltage fluctuations, overheating, and related events. Option C is incorrect because supporting utilities should be maintained, monitored, and tested as appropriate over time, not only at the beginning. ISO/IEC 27002 physical controls emphasize that technical systems depend on the physical environment. Servers, network devices, storage, and endpoint systems need appropriate location, power, cooling, cabling protection, and resilience measures. Equipment placement should also reduce unauthorized viewing, tampering, theft, and environmental exposure. The verified answer is option A because it reflects the physical protection objective in ISO/IEC 27002.
