Review is the third stage of the Plan-Do-Check-Act (PDCA) cycle, which is a four-step model for implementing and improving an information security management system (ISMS) according to ISO/IEC 27001:202212. Review involves assessing and measuring the performance of the ISMS against the established policies, objectives, and criteria12.

Assess is the verb that describes the action of reviewing the ISMS. Assess means to evaluate, analyze, or measure something in a systematic and objective manner3. Assessing the ISMS involves collecting and verifying audit evidence, identifying strengths and weaknesses, and determining the degree of conformity or nonconformity12.

Regular is the adjective that describes the frequency or interval of reviewing the ISMS. Regular means occurring or done at fixed or uniform intervals4. Reviewing the ISMS at regular intervals means conducting internal audits and management reviews periodically, such as annually, quarterly, or monthly, depending on the needs and risks of the organization12.

Suitability is one of the attributes that describes the quality or outcome of reviewing the ISMS. Suitability means being appropriate or fitting for a particular purpose, person, or situation5. Reviewing the ISMS for suitability means ensuring that it is aligned with the organization’s strategic direction, business objectives, and information security requirements12.
