During an ISO/IEC 27001 audit, auditors must obtain absolute assurance that every single process is effective and conforms to the standard requirements.

The statement is false because auditors are not required to obtain absolute assurance that every single process is effective and in full conformity with the standard's extensive requirements. Instead, the objective of an ISO/IEC 27001 audit is to assess the overall effectiveness of the Information Security Management System (ISMS) and to ensure it meets the established policies, objectives, and regulatory requirements.

Auditors typically evaluate a representative sample of processes and controls to gather sufficient evidence regarding the effectiveness of the ISMS. This approach recognizes that while some minor nonconformities might exist, they do not necessarily undermine the overall compliance and effectiveness of the system. The focus is on whether the ISMS is functioning effectively and can continuously improve rather than achieving perfection in every single process. This practical understanding allows organizations to identify areas for enhancement and to continually develop their security posture rather than being stalled by seeking absolute compliance at all times.
