FAQ's

An ISO 27001 internal audit is a self-assessment conducted by the organization (or a third party) to evaluate whether the Information Security Management System (ISMS) meets the requirements of ISO 27001 and the organization’s own policies.

ISO 27001 does not mandate a fixed interval, but internal audits must be conducted at “planned intervals” based on risk and organizational needs. Many organizations audit at least annually.

Internal audits should be done by competent and impartial auditors. They should be independent of the area being audited (i.e. not auditing their own work). The auditor should have knowledge of ISO 27001 and auditing techniques.

Internal audits are conducted by the organization to monitor and improve their ISMS, while certification audits are performed by an accredited external body to confirm conformity and award certification.

The audit report should include the audit scope, objectives, methodology, findings (nonconformities and observations), evidence, recommendations, and action plans.

Preparation involves defining the audit scope and criteria, selecting and training auditors, collecting relevant documents and evidence (policies, procedures, records), and communicating with stakeholders.
