Check: WN12-PK-000008-DC
Microsoft Windows Server 2012/2012 R2 Domain Controller STIG:
WN12-PK-000008-DC
(in versions v3 r7 through v2 r7)
Title
Active directory user accounts, including administrators, must be configured to require the use of a Common Access Card (CAC), PIV-compliant hardware token, or Alternate Logon Token (ALT) for user authentication. (Cat II impact)
Discussion
Smart cards such as the Common Access Card (CAC) support a two-factor authentication technique. This provides a higher level of trust in the asserted identity than use of the username and password for authentication.
Check Content
Verify active directory user accounts, including administrators, have "Smart card is required for interactive logon" selected. Run "PowerShell". Enter the following: "Get-ADUser -Filter {(Enabled -eq $True) -and (SmartcardLogonRequired -eq $False)} | FT Name" ("DistinguishedName" may be substituted for "Name" for more detailed output.) If any user accounts are listed, this is a finding. Alternately: To view sample accounts in "Active Directory Users and Computers" (Available from various menus or run "dsa.msc"): Select the Organizational Unit (OU) where the User accounts are located. (By default this is the Users node; however, accounts may be under other organization-defined OUs.) Right click the sample User account and select "Properties". Select the "Account" tab. If any User accounts do not have "Smart card is required for interactive logon" checked in the "Account Options" area, this is a finding.
Fix Text
Configure all user accounts, including administrator accounts, in Active Directory to enable the option "Smart card is required for interactive logon". Run "Active Directory Users and Computers" (Available from various menus or run "dsa.msc"): Select the Organizational Unit (OU) where the user accounts are located. (By default this is the Users node; however, accounts may be under other organization-defined OUs.) Right click the user account and select "Properties". Select the "Account" tab. Check "Smart card is required for interactive logon" in the "Account Options" area.
