What is the purpose of a security policy?

The purpose of a security policy is to set the framework for security practices and guidelines within an organization. It establishes the rules and procedures that govern how security is managed, helping to protect the organization’s information and assets. A well-defined security policy outlines the responsibilities of staff, the protocols they must follow, and the measures in place to mitigate risks associated with security breaches. By creating a clear framework, it ensures that all employees understand their role in maintaining security and provides a consistent approach to managing and responding to security threats.

In contrast, while defining user account settings, limiting software installations, and managing financial resources are all important aspects of an organization's operations, they are specific components or functions that may be governed by the broader context of a security policy rather than its primary purpose. Thus, they do not encapsulate the holistic approach that a security policy provides in establishing an organization’s overall security posture.
