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 organisation should regularly, at least annually, test and review its information security continuity plans to ensure that they are valid and effective in adverse situations.
Testing of continuity plans shall involve, as appropriate, stakeholders critical to each plan. The organisation should identify and document the necessary contacts with suppliers and partners
In addition, the adequacy of continuity plans and associated management mechanisms should be reassessed in the event of significant changes in operations.
