An organization has a security program that is aligned with ISO 27001. During an internal audit, it is discovered that several controls are not being applied consistently across all departments. The MOST effective corrective action is to:
Why this answer
The core issue is inconsistent control application across departments, which indicates a lack of governance and oversight rather than a policy or awareness deficiency. Establishing a centralized security oversight function directly addresses this by creating a single authority to enforce, monitor, and standardize control implementation, ensuring alignment with ISO 27001 requirements for management commitment and resource allocation (Clause 5.1 and 7.1). This corrective action provides the necessary organizational structure to drive consistent execution, which is the most effective long-term solution.
Exam trap
The trap here is that candidates confuse the symptom (inconsistent application) with the root cause (lack of governance), leading them to choose awareness training or policy updates, which are tactical fixes rather than strategic corrective actions.
Why the other options are wrong
Policy likely exists; issue is execution.
Training addresses knowledge, not enforcement.
Risk assessment would identify gaps but not fix consistency.
