In Defender PAM, what is the purpose of restricting access to necessary roles?

Restricting access to necessary roles in Defender PAM is primarily aimed at minimizing security risks and enhancing accountability. By limiting access to only those individuals who require it for their specific job functions, organizations can effectively reduce the potential for unauthorized access to sensitive information or systems. This practice not only protects against insider threats but also ensures that any actions taken within the system can be traced back to a specific user, thus promoting accountability.

In a security context, granting access only to necessary roles adheres to the principle of least privilege. This principle posits that users should have the minimum level of access required to perform their job functions, which significantly decreases the attack surface that could be exploited by malicious actors. Additionally, it fosters a culture of responsibility where employees are more aware of their actions since their access rights are closely monitored and restricted.
