The principle of least privilege is a security best practice that states that an employee should have access to only the minimum amount of resources and permissions needed to perform their job function. This principle reduces the attack surface and the potential damage that can be caused by a compromised account, a malicious insider, or human error. The principle of least privilege can be enforced by using role-based access control (RBAC) and regular audits.
