Description
Setting application account passwords to expire may cause applications to stop functioning. However, not changing them on a regular basis exposes them to attack. If managed service accounts are used, this alleviates the need to manually change application account passwords.

ℹ️ Check
Determine if manually managed application/service accounts exist. If none exist, this is NA. If passwords for manually managed application/service accounts are not changed at least annually or when an administrator with knowledge of the password leaves the organization, this is a finding. Identify manually managed application/service accounts. To determine the date a password was last changed: Domain controllers: Open "PowerShell". Enter "Get-AdUser -Identity [application account name] -Properties PasswordLastSet \| FT Name, PasswordLastSet", where [application account name] is the name of the manually managed application/service account. If the "PasswordLastSet" date is more than one year old, this is a finding. Member servers and standalone or nondomain-joined systems: Open "Command Prompt". Enter 'Net User [application account name] \| Find /i "Password Last Set"', where [application account name] is the name of the manually managed application/service account. If the "Password Last Set" date is more than one year old, this is a finding.
