This misconfiguration highlights a detailed aspect of the MITRE ATT&CK matrix and describes a security gap with regards to security hygiene.

Maintaining good hygiene for identities, including users, groups, and policies, is crucial for ensuring robust security and efficient access management. By practicing good hygiene in identity management, organizations can safeguard their systems, protect sensitive data, and maintain compliance with security standards.

Overprivileged users are a great resource for malicious actors looking to escalate their privileges or to move laterally. Long lasting identities are more susceptible to brute force compromise as they can be worked on over a longer period of time. Identities and identity resources that are not set to expire at a certain date, could slip through the cracks. In this event they could be difficult to keep track of in large, complex environments.

Mitigation: Regularly reviewing and updating user accounts, group memberships, and access policies helps prevent unauthorized access and reduces the risk of insider threats. Implementing strong password policies, multi-factor authentication, and periodic audits of permissions ensures that only authorized individuals have access to sensitive resources. Proper identity hygiene also involves promptly deactivating accounts that are no longer in use and monitoring for unusual activity.
