PECB ISO-IEC-27002-Foundation Exam - Topic 2 Question 3 Discussion

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.
