What kind of approaches does the principle of least privilege advocate?

The principle of least privilege advocates for granting users the minimum levels of access necessary to perform their job functions. This approach significantly reduces the risk of accidental or malicious misuse of sensitive information and resources. By limiting user permissions, the potential for exposure to security threats is minimized, as users can only access what they absolutely need.

This principle helps in maintaining a robust security posture by ensuring that even if an account is compromised, the damage that can be done is restricted due to the limited access. Organizations that effectively implement this principle often find it easier to manage and audit user activities, leading to a more secure and compliant environment.

For example, a regular employee should not have the same access rights as a system administrator, as the former does not require access to critical system controls or sensitive data to perform their job. This approach not only enhances security but also helps to maintain accountability, as access can be easily traced back to specific users.
