Principles of Auditing ISO 27001

ISO 19011 section 4 covers the principles of auditing.  Rather than duplicate ISO 19011, this section need only cover any aspects that are different or particularly relevant to ISMS audits such as …

  • Important but generic audit principles e.g. independent evaluation against agreed criteria, plus more specific principles aimed at ISMS audits

  • Information security is a dynamic field with frequent changes to the risks (i.e. the threats, vulnerabilities and/or impacts), controls and environment.  It is therefore important that auditors auditing information security controls should maintain knowledge of the state of the art (e.g. emerging information security threats and currently-exploited vulnerabilities) and the organizational situation (e.g. changing business processes and relationships, technology changes).
