Which document outlines security requirements and practices within an organization?

The document that outlines security requirements and practices within an organization is the Security Policy. This policy serves as a foundational framework that defines the organization's overall approach to security, including the principles, rules, and practices that govern how data and resources should be protected. It establishes expectations for employee behavior regarding security, the management of risks, and the protection of sensitive information.

A well-crafted Security Policy addresses areas such as access control, data classification, incident response, and compliance with legal or regulatory requirements. This comprehensive approach ensures that all members of the organization understand their responsibilities and the standards expected regarding security practices.

In contrast, an Incident Response Plan focuses specifically on the procedures for responding to security breaches or incidents, detailing how to manage and mitigate damage after a security event has occurred. The Business Continuity Plan is oriented towards maintaining essential functions during and after a disaster or significant disruption, while the Disaster Recovery Plan specifically outlines steps to restore IT systems and operations following a catastrophic event. Each of these documents plays an important role in the broader context of organizational security, but they do not encapsulate the overall security requirements and practices like the Security Policy does.
