Why should the auditor interview the person responsible for the ISMS in an organization?

Understanding how the organization operates with the management system in place is crucial for an auditor. This interview helps the auditor assess the effectiveness of the Information Security Management System (ISMS) and how well it is integrated into the daily operations of the organization. By discussing with the person responsible for the ISMS, the auditor can gain insights into the processes, procedures, and controls that have been implemented to manage risks and ensure the security of information.

This conversation allows the auditor to evaluate whether the practices align with the organization's security objectives and ISO/IEC 27001 requirements. It also provides an opportunity to identify any potential gaps or areas for improvement within the ISMS, which are critical for maintaining compliance and enhancing the overall security posture of the organization.

In this context, the interview serves as a foundational step in the audit process, focusing on practical, on-the-ground realities of how the ISMS is functioning, rather than just theoretical compliance with standards.
