A Disaster Recovery Plan (DRP) is a comprehensive document outlining the procedures and resources needed to restore information systems, applications, and data to operational status after a catastrophic event.

Common Vulnerability Scoring System (CVSS) is a standardized method for rating the severity of software vulnerabilities, not a plan for system recovery.

Common Vulnerability and Exposures (CVE) is a list of publicly known cybersecurity vulnerabilities, not a detailed plan for recovering information systems.
