ISO/IEC 27001 2013 Standard

The ISO/IEC 27001:2013 Standard at a glance

ISO /IEC 27001:2013 is the new Standard detailing the specifications of an Information Security Management System (ISMS) which your organisation can implement to improve the state of its information security.

ISO/IEC 27001:2013 has been written using Annex SL, which provides a common structure for management system standards. By following this structure, the Standard enables organisations to take an integrated approach to management system implementation, eliminating unnecessary duplicate processes.

ISO/IEC 27001:2013 has been updated to reflect the latest in international best practice for information security, meaning it is the most comprehensive resource for modern information security.

How does ISO/IEC 27001:2013 differ from ISO/IEC 27001:2005?

The 2013 version of ISO/IEC 27001 is substantially different to the 2005 iteration.

• The 2013 edition has been developed using Annex SL, part of a document published by ISO which provides a common approach and structure for management system standards. Since ISO/IEC 27001:2013 adopts Annex SL it more easily lends itself to integration with other management system standards.
• Whereas the 2005 edition of the Standard specified the Plan-Do-Check-Act (PDCA) cycle as the method for developing and continually improving an ISMS, the 2013 edition does not mandate this approach. Instead the 2013 edition of the Standard allows you to use either PDCA or other approaches.
• The terms and definitions that appeared in the 2005 edition of the Standard have now been removed, and instead ISO/IEC 27000:2012 is referenced as the source for terms and definitions.
• The terminology in the Standard has been updated. There is an increased focus on setting objectives, assessing performance and metrics in ISO/IEC 27001:2013.
• The risk assessment requirements in the Standard are less prescriptive and are aligned with ISO31000, the International Standard for risk management.
• The requirements for management commitment have been overhauled and are largely covered by the Leadership clause.
• The requirements for a statement of applicability in the 2013 edition have been enhanced, and the risk treatment process makes it easier to adopt control frameworks other than Annex A.
• Annex B has been deleted, and Annex A has also been revised and restructured. There are now 114 controls under 14 categories as opposed to the 133 under 11 headings in the 2005 edition of the Standard.
