Final answer:
The Disaster Recovery Plan (DRP) is designed to help an enterprise recover from a manmade or natural disaster. It is part of a suite of plans including COOP, BIA, and RMP, each with their specific focus on ensuring the resilience and continuance of business operations.
Step-by-step explanation:
The plan designed to counter a manmade or natural disaster that could cripple an enterprise is the Disaster Recovery Plan (DRP). A DRP focuses on restoring an organization's critical functions and systems after a catastrophic event. This plan serves as a "break glass in case of emergency" safeguard, which aligns with the concept described in the question of having a master plan for worst-case scenarios. It is essential to differentiate between the various types of plans: A Continuity of Operations Plan (COOP) assures that essential functions continue during and after a disaster; a Business Impact Analysis (BIA) helps identify the impacts of losing company resources; and a Risk Management Plan (RMP) entails identifying, assessing, and controlling risks.
