The ISO/IEC 27000 Family of Information Security Standards

The ISO / IEC 27000 family is a series of information security standards developed and published by the International Standards Organisation (ISO) and the International Electrotechnical Commission (IEC). These standards provide a globally recognised framework for best practice information security management.

On this page find out information about the ISO27000 family of standards, those published and those planned, the benefits they bring and links to purchase these standards.

Why use a Standard?

The ISO27001 family of Standards is broad in scope. As technology evolves, new standards are continually being developed to meet the requirements of information security. It should be noted that ISO 27001 is a specification. It sets out specific requirements, all of which must be followed, and against which an organisation's Information Security Management System (ISMS) can be audited and certified. All the other Standards in the ISO27000 family are Codes of Practice; these provide non-mandatory best practice guidelines which organisations may follow, in whole or in part, at their own discretion.

A key feature of the standards is that they are applicable to any organisation, in any sector, of any size. Key concepts which govern the standards are:

  • Organisations are encouraged to assess their own information security risks
  • Organisations should implement appropriate information security controls according to their needs
  • Guidance should be taken from the relevant standards
  • Implement continuous feedback and use of the Plan, Do, Check, Act model
  • Continually assess changes in threat and risk to information security issues.

Benefits of Using a Standard

Information security is an issue of paramount importance to all organisations. With the exponential development of technology, it is imperative that organisations protect their own assets, whilst also ensuring confidence in the clients, customers and partners they work with. By aligning itself with an ISO / IEC Standard, an organisation can:

  • Secure their own critical assets
  • Manage levels of risks
  • Improve and ensure customer confidence
  • Avoid loss of brand damage, loss of earnings or potential fines
  • Evolve their information security alongside technological developments

Key to Standards in Preparation

Below is a list of Standards and their official ISO status (International Organisation for Standardisation). The ISO has 8 stages as a Standard passes through various committees, they are thus:

  • PWI – Preliminary Work Item – Stage where initial feasibility is assessed
  • NP – New Proposal – Stage where formal scoping takes place
  • WD – Working Draft – The developmental phase
  • CD – Committee Draft – The quality control stage
  • FCD – Final Committee Draft – Ready for final approval
  • DIS – Draft International Standard – International bodies vote formally on a Standard, submitting comments
  • FDIS – Final Distribution International Standard – Standard is ready to publish
  • IS – International Standard – The Standard is published.
