Table of contents

ISO 27001 is an internationally recognized standard for Information Security Management Systems (ISMS). It provides a systematic approach to managing sensitive company information, ensuring it remains secure. The standard encompasses people, processes, and IT systems by applying a risk management process. It is part of the ISO/IEC 27000 family of standards, which are designed to help organizations keep information assets secure.

Origins and History of ISO 27001

The origins of ISO 27001 trace back to the British Standard BS 7799, which was first published in 1995.

In 2005, it was renumbered to ISO/IEC 27001 to align with the ISO/IEC 27000 series. The standard has undergone several revisions, with the most recent version being ISO/IEC 27001:2013, which was updated to ISO/IEC 27001:2022 to reflect the evolving cybersecurity landscape.
