Incidents are categorized consistent with response plans.

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 has defined a process and the team involved in responding promptly to security incidents and deciding on the appropriate actions.

The first level response process includes at least:

• effectively seeking to confirm the identified incident
• deciding on the need for immediate response
