The main body of the ISO/IEC 27001 standard, covering clauses 4 to 10, defines the requirements for establishing, implementing, maintaining, and continually improving an Information Security Management System (ISMS).
The 2022 revision introduced several important updates to these clauses aimed at enhancing clarity, aligning the standard with current business environments, and supporting a more effective and risk-based approach to information security.
While the overall structure remains consistent with the 2013 version, key additions and refinements help organizations better plan, monitor, and communicate their ISMS activities.
