ISO 27001

ISMS Requirements

What Is ISO 27001?

The international standard ISO/IEC 27001 is part of the ISO 27000 series of standards and is based on the British Standard BS7799. In 2005, it was published as an ISO standard by Joint Technical Committee JTC1 established by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Its official title is "Information technology – Security techniques – Information security management systems – Requirements".

ISO 27001 contains recommendations and controls for establishing an Information Security Management System (ISMS), covering topics such as the introduction of an ISMS process, risk management, and selection of security controls. ISO 27001 specifies requirements an organisation needs to meet using adequate security mechanisms. These mechanisms, in turn, are to be adapted to the company's individual circumstances. ISO 27001 is the only certifiable standard of the ISO 27000 series; all related publications serve exclusively as supplements since they provide either guidelines for practical implementation or industry-specific adjustments to the ISO 27001 requirements.
