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’d like to thank our assessor for his usual thorough and fully detailed attention to our system. Our ISMS is being spoken about in much awe and reverence within the wider organisation and I can honestly say that, without his support and wisdom over the last few years, this would not be happening.

It’s one thing having the required technical knowledge, it’s another thing for a consultant to apply that knowledge to the context of our organisation. To use a sporting analogy, we view cyber and information security as a marathon not a sprint. I am not a believer in doing everything all at once. Our approach has been risk based and incremental, remediating our biggest risks first before moving on. I believe this approach is far more sustainable and effective. And URM’s consultants fully understand this and are very pragmatic and tailored in their guidance and advice. They know we are not implementing ISO 27001 purely for the certificate, but more as a framework for continual improvement, and at a pace where new systems and processes can be fully understood and absorbed by our team and be business as usual.
