ISO 27001:2022 Annex A 5.27 – Learning From Information Security Incidents

Purpose of ISO 27001:2022 Annex A Control 5.27

As part of ISO 27001:2022 Annex A Control 5.2.7, incident management is established as an organic, ongoing process.

In both technical and non-technical situations, it is imperative to learn from information security events and incidents to make better decisions in the future.

You must demonstrate that the knowledge gained from analysing and resolving information security incidents will help reduce the likelihood and impact of future incidents in your information security policy.

Your commitment to continuous service improvement requires you to learn from any security incident; you should adapt the ISMS accordingly to meet the changing business landscape.

Using any information obtained, Control 5.27 aims to minimise the likelihood of recurrent incidents and mitigate their internal and external consequences.

It is recommended that incidents be placed in review and learning status after they have been resolved. The lead responder will discuss any changes that need to be made to the ISMS policies due to the incident.

Any relevant recommendations should be brought to the ISMS Board for further discussion.

Once the review and learning have been completed, updates to the policies have been made as necessary, and the relevant staff have been notified and re-trained as necessary, the cycle of information security awareness and education continues.

Ownership of Annex A Control 5.27

Considering Annex A Control 5.27 is concerned with modifying existing processes, ownership should rest with the senior management member responsible for overseeing all incident management activities.

General Guidance on Annex A Control 5.27

Organisations should implement an incident management policy that categorises and monitors the three main elements of information security incidents across their entire operation in compliance with ISO 27001:2022.

1. Type
2. Volume
3. Cost

After an incident has been closed, it should be thoroughly analysed to create procedures that:

• Develop an overarching incident management framework that includes projected scenarios and associated procedures (see Annex A Control 5.24).
• Improve all incident categories’ resilience by improving the organisation’s information security risk assessment processes and procedures.
• Enhance user awareness by highlighting real-world examples, discussing how to respond, avoiding and resolving past incidents.

ISO 27001:2013 Changes and Differences

Annex A Control 5.2.7 in ISO 27001:2022 replaces Control 16.1.6 in ISO 27001:2013 and is based on the same principles.

The same guidance is provided in ISO 27001:2022 Annex A Control 5.2.7 about recording information about information security incidents of varying types, volumes, and costs.

The control’s goal is not to improve so-called “high impact” incidents, as in ISO 27001:2013 Annex A 16.1.6. ISO 27001:2022 Annex A Control 5.2.7 is concerned with all information security incidents.
