What is the name of the plan addressing large-scale incidents that threaten the performance or security of an entire site?

The proper designation for a plan that addresses large-scale incidents threatening the performance or security of an entire site is known as a Disaster Recovery Plan. This type of plan specifically focuses on the methods and processes to recover from significant disruptions, such as natural disasters, cyberattacks, or major hardware failures, ensuring that essential functions can be restored quickly and effectively.

The Disaster Recovery Plan is crucial in determining how an organization will restore its critical operations and IT resources after a catastrophic event, which is why it plays a fundamental role in protecting organizations against loss and ensuring they can continue functioning in the aftermath of an incident. It details the procedures for maintaining and restoring technological infrastructure, identifying key resources, and establishing backup strategies.

While the Incident Response Plan is important for responding to immediate, localized incidents, and the Business Continuity Plan involves maintaining business operations during any major disruption, the Disaster Recovery Plan specifically targets the recovery of IT systems and infrastructure necessary for the overall performance and security of the entire site. Risk Management Plans focus on identifying, assessing, and prioritizing risks but do not directly address recovery from incidents.
