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.

Thank you for a very informative overview of the components in the revised Standard.
