According to ISO/IEC 27002, which of the following statements is correct?
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.
