What is the principle of granting users the minimum level of access needed for their job functions?

The principle of granting users the minimum level of access needed for their job functions is known as the Least Privilege. This security concept is crucial for maintaining a secure environment because it limits user permissions, reducing the risk of accidental or intentional misuse of sensitive information and systems. By adhering to the Least Privilege principle, organizations can ensure that users only have access to the resources necessary for their specific roles, thus minimizing the potential attack surface and enhancing overall security posture.

This principle also aligns well with best practices in access control, where the intent is to restrict permissions as tightly as possible while still allowing users to perform their essential tasks. Properly implementing this principle helps organizations comply with various regulatory requirements relating to data privacy and security, as sensitive information is better protected from unauthorized access.
