A Disaster recovery plan (DRP) is a detailed document that describes the procedures and actions to be implemented to enable an organisation to resume its critical activities as quickly as possible after a major IT security incident. This incident can take various forms: cyber attack, hardware failure, natural disaster, etc.
Difference with PCA :
The Business Continuity Plan (BCP) is broader and includes the DRP. BCP focuses on maintaining activities during a crisis, while DRP focuses on recovery after a shutdown.
