What does the principle of least privilege entail?

The principle of least privilege is a foundational concept in security management that dictates that individuals should only be granted the minimum level of access—or permissions—necessary to perform their job functions. This approach minimizes the risk of accidental or malicious misuse of sensitive information or systems. By granting users access solely to the information they need, the organization limits exposure to potential breaches and reduces the impact of an insider threat or compromised account. For example, if a user only needs to view reports and not modify them, giving them edit permissions increases the risk unnecessarily. This principle is applied in various contexts, such as user account management, application access, and server configurations, effectively enforcing a tighter security posture. Other choices do not align with the principle of least privilege; for instance, granting full access to all systems is contrary to the principle as it opens up every aspect of the system to all users, greatly increasing security risks. Similarly, users having the ability to change permissions as needed gives them power that can lead to unintentional or intentional abuse of access rights. Temporary access to secure data may seem reasonable in some contexts, but it does not inherently enforce the level of security that the least privilege principle aims to uphold continuously.
