Recovery plans incorporate lessons learned.

Organisation should have a process to analyse and learn from the operational resilience testing results, from actual cyber security incidents and from experiences of activating continuity plans. Relevant information and experiences should be exchanged with counterparts.

The lessons learned should be incorporated in to the cyber risk management process.

The organisation's top management should have a yearly report about the lessons from senior ICT staff along with recommendations for improvements.

The organisation regularly develops its continuity plans by analyzing the testing of the plans, training and their actual use in real situations.

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
