What is the difference between ISO 27001 and ISO 27002?

ISO 27002 is a supporting document that provides guidance on 93 best practice information security controls that can be implemented to help mitigate the risks identified by your ISO 27001 risk assessment.   The ISO/IEC 27002:20022 Standard restructured and rationalised the previous 114 controls, and added a further 11 controls to the structure, reflecting the evolving IS technologies and the emergence of new threats.

In fact, these 93 controls are replicated in Annex A of ISO 27001 and you are required to consider all of them when determining the most appropriate actions to mitigate your risks.

The controls are separated into 4 main themes organisational, people, technological and physical.  The Standard also introduced 5 ‘attributes’, where you can assign hashtags to controls to enable you to filter, sort, or present controls in different ways.  More information can be found here.

We would like to pass on our gratitude to our consultant for all his hard work and advice during our 3-year re-certification and assessment against the new Standard. After seven days of auditing, we have two OFIs that the assessors have put forward from the audits. This pays testament to our URM consultant, his hard work, eye for detail and advice given, both during the audits and during all the works beforehand.
