Configuration of whitelisting applications will vary by the program. AppLocker is a whitelisting application built into Windows Server.
 
If AppLocker is used, it is configured through group policy in Computer Configuration &gt;&gt; Windows Settings &gt;&gt; Security Settings &gt;&gt; Application Control Policies &gt;&gt; AppLocker.
 
Implementation guidance for AppLocker is available in the NSA paper "Application Whitelisting using Microsoft AppLocker" at the following link:

If an application whitelisting program is not in use on the system, this is a finding.
 
Configuration of whitelisting applications will vary by the program.
 
AppLocker is a whitelisting application built into Windows Server. A deny-by-default implementation is initiated by enabling any AppLocker rules within a category, only allowing what is specified by defined rules.
 
If AppLocker is used, perform the following to view the configuration of AppLocker:
 
Open "PowerShell".
 
If the AppLocker PowerShell module has not been imported previously, execute the following first:
 
Import-Module AppLocker
 
Execute the following command, substituting [c:\temp\file.xml] with a location and file name appropriate for the system:
 
Get-AppLockerPolicy -Effective -XML &gt; c:\temp\file.xml
 
This will produce an xml file with the effective settings that can be viewed in a browser or opened in a program such as Excel for review.

Ensuring the confidentiality of transmitted information requires the operating system to take measures in preparing information for transmission. This can be accomplished via access control and encryption.
 
Use of this requirement will be limited to situations where the data owner has a strict requirement for ensuring data integrity and confidentiality is maintained at every step of the data transfer and handling process. When transmitting data, operating systems need to support transmission protection mechanisms such as TLS, encrypted VPNs, or IPsec.

Emergency administrator accounts are different from infrequently used accounts (i.e., local logon accounts used by system administrators when network or normal logon/access is not available). Infrequently used accounts are not subject to automatic termination dates. Emergency accounts are accounts created in response to crisis situations, usually for use by maintenance personnel.

Open "PowerShell" with elevated privileges (run as administrator).
 
Enter the following:
 
"Get-CimInstance -ClassName Win32_DeviceGuard -Namespace root\Microsoft\Windows\DeviceGuard"
 
If "RequiredSecurityProperties" does not include a value of "2" indicating "Secure Boot" (e.g., "{1, 2}"), this is a finding.
 
If "Secure Boot and DMA Protection" is configured, "3" will also be displayed in the results (e.g., "{1, 2, 3}").
 
If "VirtualizationBasedSecurityStatus" is not a value of "2" indicating "Running", this is a finding.
 
Alternately:
 
Run "System Information".
 
Under "System Summary", verify the following:
 
If "Device Guard Virtualization based security" does not display "Running", this is finding.
 
If "Device Guard Required Security Properties" does not display "Base Virtualization Support, Secure Boot", this is finding.
 
If "Secure Boot and DMA Protection" is configured, "DMA Protection" will also be displayed (e.g., "Base Virtualization Support, Secure Boot, DMA Protection").
 
The policy settings referenced in the Fix section will configure the following registry values. However, due to hardware requirements, the registry values alone do not ensure proper function.

Kerberos tickets have a limited lifetime so the time an attacker has to implement an attack is limited. This policy controls how long TGTs can be renewed. With Kerberos, the user's initial authentication to the domain controller results in a TGT, which is then used to request Service Tickets to resources. Upon startup, each computer gets a TGT before requesting a service ticket to the domain controller and any other computers it needs to access. For services that start up under a specified user account, users must always get a TGT first and then get Service Tickets to all computers and services accessed.

Review user account mappings to PKI certificates.
 
Open "Windows PowerShell".
 
Enter "Get-ADUser -Filter * | FT Name, UserPrincipalName, Enabled".
 
Exclude disabled accounts (e.g., DefaultAccount, Guest) and the krbtgt account.
 
If the User Principal Name (UPN) is not in the format of an individual's identifier for the certificate type and for the appropriate domain suffix, this is a finding.
 
For standard NIPRNet certificates the individual's identifier is in the format of an Electronic Data Interchange - Personnel Identifier (EDI-PI).
 
Alt Tokens and other certificates may use a different UPN format than the EDI-PI which vary by organization. Verified these with the organization.
 
NIPRNet Example:
Name - User Principal Name
User1 - 1234567890@mil
 
See PKE documentation for other network domain suffixes.
 
If the mappings are to certificates issued by a CA authorized by the Component's CIO, this is a CAT II finding.</check-content></check></Rule></Group><Group id="V-224994"><title>SRG-OS-000105-GPOS-00052</title><description>&lt;GroupDescription&gt;&lt;/GroupDescription&gt;</description><Rule id="SV-224994r569186_rule" weight="10.0" severity="medium"><version>WN16-DC-000310</version><title>Active Directory user accounts, including administrators, must be configured to require the use of a Common Access Card (CAC), Personal Identity Verification (PIV)-compliant hardware token, or Alternate Logon Token (ALT) for user authentication.</title><description>&lt;VulnDiscussion&gt;Smart cards such as the CAC support a two-factor authentication technique.

In the case of an LDAP server, this means that an attacker could cause a client to make decisions based on false records from the LDAP directory. The risk of an attacker pulling this off can be decreased by implementing strong physical security measures to protect the network infrastructure. Furthermore, implementing Internet Protocol security (IPsec) authentication header mode (AH), which performs mutual authentication and packet integrity for Internet Protocol (IP) traffic, can make all types of man-in-the-middle attacks extremely difficult.

Severity Override Guidance: The AO can allow the severity override if they have reviewed the overall protection provided to the affected servers that are not capable of complying with the Credential Guard requirement. Items that should be reviewed/considered for compliance or mitigation for non-Credential Guard compliance are:
 
The use of Microsoft Local Administrator Password Solution (LAPS) or similar products to control different local administrative passwords for all affected affected servers. This is to include a strict password change requirement (60 days or less).
….
Strict separation of roles and duties. Server administrator credentials cannot be used on Windows 10 desktop to administer it. Documentation of all exceptions should be supplied.
….
Use of a Privileged Access Workstation (PAW) and adherence to the Clean Source principle for administering affected affected servers.
….
Boundary Protection that is currently in place to protect from vulnerabilities in the network/servers.
….
Windows Defender rule block credential stealing from LSASS.exe is applied. This rule can only be applied if Windows Defender is in use.
….
The overall number of vulnerabilities that are unmitigated on the network/servers.

Current hardware and virtual environments may not support virtualization-based security features, including Credential Guard, due to specific supporting requirements, including a TPM, UEFI with Secure Boot, and the capability to run the Hyper-V feature within a virtual machine.
 
Open "PowerShell" with elevated privileges (run as administrator).
 
Enter the following:
 
"Get-CimInstance -ClassName Win32_DeviceGuard -Namespace root\Microsoft\Windows\DeviceGuard"
 
If "SecurityServicesRunning" does not include a value of "1" (e.g., "{1, 2}"), this is a finding.
 
Alternately:
 
Run "System Information".
 
Under "System Summary", verify the following:
 
If "Device Guard Security Services Running" does not list "Credential Guard", this is finding.
 
The policy settings referenced in the Fix section will configure the following registry value. However, due to hardware requirements, the registry value alone does not ensure proper function.
