ISO 27001:2006

We've received the following question: "... ISO 27001 certificate was produced against ISO 27001: 2006, can’t find any reference of this standard. Could you provide some context, is this different from 2005 version?" Answer: The official standard ISO 27001 issued by ISO/IEC (International Organization for Standardization (ISO) and the International Electrotechnical Commission) was published in 2005, but some countries made their own publication of the standard, usually translated to the country language. Each country member of the ISO committee has a National Normalization Organization and perhaps the standard you are referring to is a National version of the standard issued in 2006. If you are certified in ISO 27001:2006, it seems that you are certified against a National Standard based on the ISO 27001:2005. Both version should be the same. Thanks
