The ISO/IEC 27000 Family of Information Security Standards

The ISO/IEC 27000-series (also known as the 'ISO 27000 Family of Standards') comprises mutually supporting information security standards that together provide a globally recognised framework for best-practice information security management.

The series is developed and published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).


Why use an ISO/IEC 27000-series standard?

The ISO 27000 family of standards is broad in scope and is applicable to organisations of all sizes and in all sectors. As technology continually evolves, new standards are developed to address the changing requirements of information security in different industries and environments.

Standards in development

An ISO standard follows a six-step development process before publication, and at each stage is ascribed an appropriate abbreviation to denote its status:

  • Preliminary stage:
    PWI (Preliminary Work Item) – Initial feasibility is assessed.
  • Proposal stage
    NP (New Proposal) – Formal scoping takes place.
  • Preparatory stage
    WD (Working Draft) – The standard is developed.
  • Committee stage
    CD (Committee Draft) – Quality control takes place.
  • Enquiry stage
    FCD (Final Committee Draft) – The standard is ready for final approval.
    DIS (Draft International Standard) – International bodies vote formally on the standard, and submit comments.
  • Approval stage
    FDIS (Final Distribution International Standard) – The standard is ready to publish.
  • Publication stage
    IS (International Standard) – The standard is published.

The development process follows this pattern:

PWI >>   NP >>   WD >>   CD >>   DIS >>   FDIS >>   IS
