Incident mitigation

All security incidents are addressed in a consistent manner to improve security based on what has happened.

In the incident treatment process:

• the reported incident is confirmed (or found unnecessary to record)
• the type and cause of incident is documented
• the risks associated with the incident are documented
• the risks are re-evaluated and treated if that is necessary after the incident
• risk mitigation measures or a decision their acceptance is documented
• people who need to be informed of the results of the incident treatment are identified (including external ones)
• possible need for a post-incident analysis is determined

The organization must document in advance procedures for responding to security breaches to ensure the actions of related departments, customers, and other critical partners in the event of a security breach.
