The internationally acclaimed standard for information security management (ISO/IEC 27001) and accompanying ISO/IEC 27002:2013, ‘Code of practice for information security management controls’ have been revised. Following the publication of an initial draft international standard (DIS) and extensive public consultation, both ISO/IEC 27001 and ISO/IEC 27002 have passed their final draft standard (FDIS) ballots and proceeded to final publication.
What are the main changes?
- The revised standard has been written using the new high level structure, which is common to all new management systems standards. This will allow easy integration when implementing more than one management system
- Terminology changes have been made and some definitions have been removed or relocated
- Risk assessment requirements have been aligned with BS ISO 31000
- Management commitment requirements have a focus on “leadership”
- Preventive action has been replaced with “actions to address, risks and opportunities”
- SOA requirements are similar, with more clarity on the need to determine controls by the risk treatment process
- Controls in Annex A have been modified to reflect changing threats, remove duplication and have a more logical grouping. Specific controls have also been added around cryptography and security in supplier relationships
- Greater emphasis is on setting objectives, monitoring performance and metrics
