What does the principle of least privilege dictate?

The principle of least privilege stipulates that users should only have the minimum levels of access necessary to perform their job functions. This approach minimizes potential security risks by limiting access to sensitive information and systems, thus reducing the chances of accidental or intentional misuse. By ensuring that individuals can only access the resources essential for their role, organizations can protect critical data and maintain better overall security posture.

In practical applications, implementing the principle of least privilege can involve role-based access control (RBAC), where permissions are granted based on job responsibilities, and continual reviewing of permissions to ensure they align with current job requirements. This careful allocation of access helps organizations mitigate risks associated with unauthorized access and potential breaches.
