Fix Recommendation

Remove emergency administrator accounts after a crisis has been resolved or configure the accounts to automatically expire within 72 hours.

Domain accounts can be configured with an account expiration date, under "Account" properties.

Local accounts can be configured to expire with the command "Net user [username] /expires:[mm/dd/yyyy]", where username is the name of the temporary user account.

Check Contents

Determine if emergency administrator accounts are used and identify any that exist. If none exist, this is NA.

If emergency administrator accounts cannot be configured with an expiration date due to an ongoing crisis, the accounts must be disabled or removed when the crisis is resolved.

If emergency administrator accounts have not been configured with an expiration date or have not been disabled or removed following the resolution of a crisis, this is a finding.

Domain Controllers:

Open "PowerShell".

Enter "Search-ADAccount –AccountExpiring | FT Name, AccountExpirationDate".

If "AccountExpirationDate" has been defined and is not within 72 hours for an emergency administrator account, this is a finding.

Member servers and standalone systems:

Open "Command Prompt".

Run "Net user [username]", where [username] is the name of the emergency account.

If "Account expires" has been defined and is not within 72 hours for an emergency administrator account, this is a finding.
