About This Standard

ISO/IEC 27001 is the world's leading information security management system standard, specifying requirements for establishing, implementing, maintaining, and continuously improving an ISMS. The 2022 revision restructured Annex A into four control themes — organisational, people, physical, and technological — and introduced 11 new controls addressing areas including threat intelligence, cloud security, and data masking.

The standard's core is a risk-based approach: organisations identify information security risks, select appropriate controls from Annex A (or elsewhere), and continuously monitor their effectiveness. The Statement of Applicability documents which controls apply and why.

ACI-certified ISO/IEC 27001 auditors demonstrate competency in assessing ISMS design, evaluating risk treatment decisions, and reviewing the effectiveness of all 93 Annex A controls.
