Learning from information security incidents

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

The organization has defined procedures to ensure that the original reporter and other personnel involved in the incident are informed of the outcome of the incident management.

Linked personnel can be documented on an optional field on the incident documentation template.
