ISO 27002 is an internationally recognized standard that provides guidelines for organizational information security management practices. It is part of the ISO/IEC 27000 family of standards, which are designed to help organizations keep their information assets secure. ISO 27002 specifically offers a comprehensive set of controls and best practices for implementing, maintaining, and improving an Information Security Management System (ISMS).

Origins and History of ISO 27002

The origins of ISO 27002 can be traced back to the British Standard BS 7799, which was first published in 1995. This standard was developed by the British Standards Institution (BSI) and was later adopted by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) as ISO/IEC 17799 in 2000. In 2005, it was renumbered to ISO/IEC 27002 to align with the ISO/IEC 27000 series. The standard has undergone several revisions, with the most recent version being published in 2013, reflecting the evolving landscape of information security threats and technologies.
