Which document outlines the procedure for responding to security breaches?

The document that outlines the procedure for responding to security breaches is the Incident Response Plan. This plan is specifically designed to prepare an organization for handling and managing incidents that may compromise the security of its information systems.

An Incident Response Plan delineates the steps to be taken when a security incident occurs, including identification, containment, eradication, recovery, and lessons learned. It establishes roles and responsibilities for the incident response team and outlines communication protocols, ensuring that the organization can react swiftly and effectively to minimize damage and restore normal operations.

In contrast, while the Disaster Recovery Plan focuses on restoring critical operations after a major incident such as a natural disaster or significant technical failure, it does not detail the specific procedures for addressing security breaches. The Business Continuity Plan is broader and covers how an organization can continue its operations during and after disruptive events, which may include but are not limited to security breaches. The Security Policy Document sets the overall framework for organizational security practices and establishes guidelines but does not provide the actionable steps required for individual incidents.

Thus, the Incident Response Plan is the essential document for outlining procedures specifically tailored for responding to security breaches effectively.
