What does a security policy outline?

A security policy is a formal document that outlines an organization's overall approach to protecting its information assets, including data, personnel, and physical environments. This policy provides a framework for establishing security objectives and guidelines, helping to ensure compliance with legal and regulatory requirements, and setting expectations for behavior among employees and stakeholders.

By clearly defining the security measures, responsibilities, and procedures, the policy serves as a guiding document for the organization's culture around security. It covers the rationale behind security practices as well as the strategies employed to manage risks and mitigate threats. Essentially, a security policy acts as the foundation for maintaining the confidentiality, integrity, and availability of data.

In contrast, the other options pertain to specific aspects that are not the primary focus of a security policy. While budget limitations are important for implementing security measures, they do not constitute the policy itself. Similarly, a security policy does not provide a comprehensive list of software solutions or chronicle historical changes in security measures; those items are more operational concerns or historical records than strategic documents outlining policies.
