Cyber Security Standards - ISO 27002

ISO 27002

ISO/IEC 27002 incorporates mainly part 1 of the BS 7799 good security management practice standard. The latest versions of BS7799 is BS7799-3. Sometimes ISO/IEC 27002 is therefore referred to as ISO 17799 or BS 7799 part 1 and sometimes it refers to part 1 and part 7. BS 7799 part 1 provides an outline or good practice guide for cyber security management; whereas BS 7799 part 2 and ISO 27001 are normative and therefore provide a framework for certification. ISO/IEC 27002 is a high level guide to cyber security. It is most beneficial as explanatory guidance for the management of an organisation to obtain certification to the ISO 27001 standard. The certification once obtained lasts three years. Depending on the auditing organisation, no or some intermediate audits may be carried out during the three years. ISO 27001 (ISMS) replaces BS 7799 part 2, but since it is backward compatible any organization working toward BS 7799 part 2 can easily transition to the ISO 27001 certification process. There is also a transitional audit available to make it easier once an organization is BS 7799 part 2-certified for the organization to become ISO 27001-certified. ISO/IEC 27002 states that information security is characterized by integrity, confidentiality, and availability. The ISO/IEC 27002 standard is arranged into eleven control areas; security policy, organizing information security, asset management, human resources security, physical and environmental security, communication and operations, access controls, information systems acquisition/development/maintenance, incident handling, business continuity management, compliance.
