Which principle dictates that users should have minimal access needed for their roles?

The principle that dictates users should have minimal access needed for their roles is known as the Principle of Least Privilege. This principle emphasizes that each user should only have the permissions necessary to perform their job functions, no more and no less. By limiting access in this way, organizations can reduce the risk of accidental or malicious misuse of data and resources, minimizing the attack surface and the potential for security breaches.

When users are granted excessive privileges, it can lead to various vulnerabilities, including the unintended disclosure of sensitive information or the ability to make unauthorized changes to critical systems. The Principle of Least Privilege helps mitigate these risks by enforcing strict access controls tailored to each user's specific tasks and responsibilities.

This approach is essential in maintaining a secure environment, as it directly contributes to overall risk management by ensuring that access rights are aligned with job functions, thereby enhancing the security posture of the organization.
