A checklist is a tool that helps auditors to collect and verify information relevant to the audit objectives and scope. It can provide the following advantages:

Ensuring relevant audit trails are followed: A checklist can help auditors to identify and trace the sources of evidence that support the conformity or nonconformity of the audited criteria. It can also help auditors to avoid missing or overlooking any important aspects of the audit.

Ensuring the audit plan is implemented: A checklist can help auditors to follow and fulfil the audit plan, which describes the arrangements and details of the audit, such as the objectives, scope, criteria, schedule, roles, and responsibilities. It can also help auditors to manage their time and resources effectively and efficiently.

The other options are not advantages of using a checklist, but rather:

Using the same checklist for every audit without review: This is a disadvantage of using a checklist, as it can lead to a rigid and ineffective audit approach. A checklist should be tailored and adapted to each specific audit, taking into account the context, risks, and changes of the auditee and the audit criteria. A checklist should also be reviewed and updated periodically to ensure its validity and relevance.

Restricting interviews to nominated parties: This is a disadvantage of using a checklist, as it can limit the scope and depth of the audit. A checklist should not prevent auditors from interviewing other relevant parties or sources of information that may provide valuable evidence or insights for the audit. A checklist should be used as a guide, not as a constraint.

Reducing audit duration: This is not necessarily an advantage of using a checklist, as it depends on various factors, such as the complexity, size, and maturity of the auditee’s ISMS, the availability and quality of evidence, the competence and experience of the auditors, and the level of cooperation and communication between the auditors and the auditee. A checklist may help reduce audit duration by improving efficiency and organization, but it may also increase audit duration by requiring more evidence or verification.

Not varying from the checklist when necessary: This is a disadvantage of using a checklist, as it can result in a superficial or incomplete audit. A checklist should not prevent auditors from exploring or investigating any issues or concerns that arise during the audit, even if they are not included in the checklist. A checklist should be used as a support, not as a substitute.

ISO/IEC 27001 requires organizations to comply with applicable legal, statutory, regulatory, and contractual requirements, including those pertaining to information security. These requirements must be identified, documented, and kept up to date as part of the organization's ISMS.

According to ISO/IEC 27001, the scope of an ISMS must be defined and documented. This documentation should include the boundaries and applicability of the information security management system, which helps in defining what information, locations, and assets are covered under the ISMS.

Yes, it is acceptable for the internal auditor to follow-up on the implementation of corrective actions until verified by the external auditor during the next surveillance audit. This practice supports continuous improvement and ensures that corrective actions are effectively implemented and maintained over time.
