The ISO27k standards are being actively developed, hence the information on this website is somewhat vague in respect of draft standards and those that are changing rapidly*. The content, scope and titles of standards often change during the slow drafting and approvals process. Once published, however, the standards generally remain static for several years, giving us time to catch up!

The other ISO27k standards page concerns Study Periods and New Work Item Proposals for additional standards that haven’t yet been fully scoped, approved or numbered.


Please do not rely on anything we say here:
we do our best to be accurate and complete
but the
published standards are definitive!


Most of the information on this website has been gathered from ISO/IEC and similar official sources, including incomplete working drafts of standards currently in preparation. It includes a number of personal comments and asides by the author/owner of this website that are totally informal and often distinctly biased, cynical, verging on jaundiced. is NOT an official ISO/IEC organ. We have no formal relationship with ISO/IEC, other than being members of the committee ISO/IEC JTC 1/SC 27 “Information security, cybersecurity and privacy protection”. We try hard to understand and describe what is going on with the ISO27k standards but we cannot totally guarantee the integrity (as in completeness and accuracy) of all the information we provide here. Please contact ISO, IEC or your own national standards body (e.g. ANSI, BSI, SNZ) for “official” information, ideally liaising with your national body’s members of SC 27 or working through affiliated organisations such as ISACA and CSA.

* “Rapidly” is decidedly tongue-in-cheek. International standards rush along much as a replete snail rushes towards a nasty lettuce.

PS Since we sometimes fall behind with updates to this website, you may like to monitor the official ISO list of published ISO27k standards for the current, official status.  Officially.
