Sometimes an unexpected event, such as a fire, flood, or equipment failure, can cause downtime. In order to be able to continue operations as quickly and smoothly as possible, continuity planning is carried out, i.e. planning the operations in advance for these exceptional situations.
Each continuity plan shall contain at least the following information:
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.
The organization has to include disaster recovery in their continuity planning. Relevant disasters for the planning are natural disasters (e.g floods, earthquake, hurricanes) and human caused disasters (e.g terror attack, chemical attack/incident, insider attack).
In disaster planning there is greater emphasis on the returning operations to normal levels safely than in continuity planning. After this focus moves to resuming normal operations.
The continuity plans must be updated at least annually or after significant changes.
