What is one way to find evidence according to the ISO 27001 guidelines?

Reviewing records and documents is a fundamental method for finding evidence in accordance with ISO 27001 guidelines. This approach allows auditors to assess compliance with the standards and controls set within an Information Security Management System (ISMS). By examining existing documentation, including policies, procedures, incident reports, and audit logs, auditors can identify whether the organization is following the required processes and effectively managing security risks.

Documentation serves as a tangible source of evidence that illustrates how security measures are implemented and maintained. It also helps in tracking any changes over time, thereby providing a comprehensive view of the organization’s adherence to ISO 27001 requirements.

Other options may not provide sufficient or reliable means for sourcing evidence. Waiting for a formal complaint may restrict the opportunity to uncover systemic issues proactively. Relying solely on automated systems could lead to a narrow perspective, as it may overlook human factors or contextual nuances that are critical to a thorough assessment. Gathering information from public records can be useful in some contexts, but it may not offer the specific, internal insights necessary for evaluating an organization's adherence to its own ISMS policies and procedures.
