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, and regretfully we sometimes fall months behind with updates*. 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 notes “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: only the published standards are definitive!

Most of the information on this website has been gathered from ISO/IEC and similar official sources plus various unofficial sources such as newsletters from ISMS user groups, presentations by and private communications from members of various national standards bodies active on ISO27k business. It includes a number of personal comments and asides by the author/owner of this website, Gary Hinson, that are totally informal and often distinctly biased. ISO27001security.com is NOT an official ISO/IEC organ. We have no formal relationship with ISO/IEC. We simply do our best to present the picture 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. NIST/ANSI, BSI, SNZ) for “official” information.
