Information technology -- Security techniques -- Information security management systems -- Overview and vocabulary

ISO/IEC 27000:2009 provides an overview of information security management systems, which form the subject of the information security management system (ISMS) family of standards, and defines related terms. As a result of implementing ISO/IEC 27000:2009, all types of organization (e.g. commercial enterprises, government agencies and non-profit organizations) are expected to obtain:

  1. an overview of the ISMS family of standards;
  2. an introduction to information security management systems (ISMS);
  3. a brief description of the Plan-Do-Check-Act (PDCA) process; and
  4. an understanding of terms and definitions in use throughout the ISMS family of standards.

The objectives of ISO/IEC 27000:2009 are to provide terms and definitions, and an introduction to the ISMS family of standards that:

  1. define requirements for an ISMS and for those certifying such systems;
  2. provide direct support, detailed guidance and/or interpretation for the overall Plan-Do-Check-Act (PDCA) processes and requirements;
  3. address sector-specific guidelines for ISMS; and
  4. address conformity assessment for ISMS.
