The impact of the incident is understood.

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

Organization assesses cyber security risks by responding to situations where security has been mildly or severely compromised. The documentation shall include at least the following:

• Description of the incident
• Risks associated with the incident
• New tasks introduced as a result of the incident
• Other measures taken due to the incident

If it is difficult to identify the source of a security incident based on the primary treatment, a separate follow-up analysis is performed for the incident, in which the root cause is sought to be identified.

The knowledge gained from analyzing and resolving security incidents should be used to reduce the likelihood of future incidents and their impact.

The organization regularly analyzes incidents as a whole. This process examines the type, amount and cost of incidents with the aim of identifying recurrent and significant incidents that need more action.

If recurrent incidents requiring response are identified, based on them:

• new management tasks are created or current ones expanded
• security guidelines in this area are refined or extended
• a case example of the incident is created that is used to train staff to respond to or avoid similar incidents
