Verify that the site is applying all security-related patches released by Microsoft. Determine the local site method for doing this (e.g., connection to a WSUS server, local procedure, etc.). Severity Override: If any of the patches not installed are Microsoft ‘Critical’, then the category code should be elevated to ‘1’. Note: If a penetration scan has been run on the network, it will report findings if security-related updates are not applied. Then, this check may be marked as “Not Applicable”. Some applications (such as DMS and GCSS) use a system release process to keep systems current. If this is the case, then these systems should be at the current release.

To determine the date a password was last changed: Domain controllers: Open "Windows PowerShell" with elevated privileges (run as administrator). Enter "Import-Module ActiveDirectory". (This only needs to be run once during a PowerShell session.) Enter "Get-ADUser -Identity [application account name] -Properties PasswordLastSet | FL 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 systems: Open "Windows PowerShell" or "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. Note: Other queries or tools may be used. The organization must be able to demonstrate the results are valid and meet the intent of the requirement.
Establish a policy that requires application/service account passwords that are manually managed to be at least 15 characters in length. It must also require the passwords be changed at least annually or when an administrator with knowledge of the password leaves the organization. Ensure the policy is enforced. Windows automatically addresses passwords for Managed Service Accounts.
