What is the main focus of the principle of least privilege?

The principle of least privilege emphasizes that users should have the minimum level of access—or permissions—necessary to perform their job functions effectively. This approach helps to enhance security by limiting the potential damage that can occur from accidental or malicious actions. By restricting access rights, organizations can mitigate risks associated with unauthorized access to sensitive data and systems. It ensures that users cannot access information or perform actions that are outside the scope of their responsibilities, thereby reducing vulnerabilities and making it easier to manage and control security within the environment.

In contrast, maximizing user access could lead to increased risks and potential breaches, while providing the highest security clearance indiscriminately can expose critical resources to unnecessary threats. Educating users on security practices is important, but it does not directly correlate with access rights and is not the main focus of the principle of least privilege. Therefore, minimizing access rights tailored to job functions stands out as the most relevant focus for security best practices.
