Vulnerability discussion

The lack of password protection enables anyone to gain access to the information system, which opens a backdoor opportunity for intruders to compromise the system as well as other resources within the same administrative domain.

Check content

Review the password required status for enabled user accounts. Open "Windows PowerShell" with elevated privileges (run as administrator). Domain Controllers: Enter "Import-Module ActiveDirectory". (This only needs to be run once during a PowerShell session.) Enter 'Get-ADUser -Filter * -Properties PasswordNotRequired | Where {$_.PasswordNotRequired -eq "True"} | FT Name, PasswordNotRequired, Enabled -AutoSize'. Exclude disabled accounts (e.g., Guest). Domain accounts requiring smart card (CAC/PIV) may also be excluded. If "PasswordNotRequired" is "True" for any enabled user account, this is a finding. Member servers and standalone systems: Enter 'Get-WMIObject -Class Win32_Useraccount -Filter "PasswordRequired=False and LocalAccount=True" | FT Name, PasswordRequired, Disabled, LocalAccount -AutoSize'. Exclude disabled accounts (e.g., Guest). If any enabled user accounts are returned with a "PasswordRequired" status of "False", 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.

Fix text

Configure all enabled accounts to require passwords. The password required flag can be set by entering the following on a command line: "Net user [username] /passwordreq:yes", substituting [username] with the name of the user account.
