As with most major ISO standards, ISO 17799 is periodically revised. The most recent version was published in June 2005(ISO/IEC 17799:2005). Changes include the closer integration with the BS7799-2
(the international version of which is ISO27001
) approach, and a re-organization of the controls within. Important advice on information security risk analysis which merited only a brief mention in the preface of the previous version is promoted to a main section.
