Overview​

Highly privileged accounts with old passwords are prime targets for password spraying, credential theft, and persistence. Reviewing password age for built-in administrator style accounts helps validate that sensitive credentials are rotated appropriately.

  • Credential risk reduction: Long-lived privileged passwords increase exposure.
  • Control validation: Supports verification of password rotation practices.
  • Exception tracking: Highlights accounts with non-expiring privileged credentials.

Security Recommendation​

  • Rotate passwords for privileged accounts on a defined schedule.
  • Avoid non-expiring passwords on privileged identities wherever possible.
  • Review break-glass or emergency accounts separately with compensating controls.

How the Test Works​

This test lists built-in administrator style accounts and reports PasswordLastSet, calculated password age in days, and PasswordNeverExpires state.
