Windows Server 2022 must use separate, NSA-approved (Type 1) cryptography to protect the directory data in transit for directory service implementations at a classified confidentiality level when replication data traverses a network cleared to a lower level than the data.
Directory data that is not appropriately encrypted is subject to compromise. Commercial-grade encryption does not provide adequate protection when the classification level of directory data in tran...Rule Medium Severity -
Windows Server 2022 directory data (outside the root DSE) of a nonpublic directory must be configured to prevent anonymous access.
To the extent that anonymous access to directory data (outside the root DSE) is permitted, read access control of the data is effectively disabled. If other means of controlling access (such as net...Rule High Severity -
Windows Server 2022 directory service must be configured to terminate LDAP-based network connections to the directory server after five minutes of inactivity.
The failure to terminate inactive network connections increases the risk of a successful attack on the directory server. The longer an established session is in progress, the more time an attacker ...Rule Low Severity -
Windows Server 2022 Active Directory Group Policy objects must be configured with proper audit settings.
When inappropriate audit settings are configured for directory service database objects, it may be possible for a user or process to update the data without generating any tracking data. The impact...Rule Medium Severity -
Windows Server 2022 Active Directory Domain object must be configured with proper audit settings.
When inappropriate audit settings are configured for directory service database objects, it may be possible for a user or process to update the data without generating any tracking data. The impact...Rule Medium Severity -
Windows Server 2022 Active Directory Infrastructure object must be configured with proper audit settings.
When inappropriate audit settings are configured for directory service database objects, it may be possible for a user or process to update the data without generating any tracking data. The impact...Rule Medium Severity -
Windows Server 2022 Active Directory RID Manager$ object must be configured with proper audit settings.
When inappropriate audit settings are configured for directory service database objects, it may be possible for a user or process to update the data without generating any tracking data. The impact...Rule Medium Severity -
Windows Server 2022 must be configured to audit Account Management - Computer Account Management successes.
Maintaining an audit trail of system activity logs can help identify configuration errors, troubleshoot service disruptions, and analyze compromises that have occurred, as well as detect attacks. A...Rule Medium Severity -
Windows Server 2022 must be configured to audit DS Access - Directory Service Access successes.
Maintaining an audit trail of system activity logs can help identify configuration errors, troubleshoot service disruptions, and analyze compromises that have occurred, as well as detect attacks. A...Rule Medium Severity -
Windows Server 2022 must be configured to audit DS Access - Directory Service Access failures.
Maintaining an audit trail of system activity logs can help identify configuration errors, troubleshoot service disruptions, and analyze compromises that have occurred, as well as detect attacks. A...Rule Medium Severity -
Windows Server 2022 domain Controller PKI certificates must be issued by the DoD PKI or an approved External Certificate Authority (ECA).
A PKI implementation depends on the practices established by the Certificate Authority (CA) to ensure the implementation is secure. Without proper practices, the certificates issued by a CA have li...Rule High Severity -
Windows Server 2022 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.
Smart cards such as the 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. ...Rule Medium Severity -
Windows Server 2022 domain controllers must be configured to allow reset of machine account passwords.
Enabling this setting on all domain controllers in a domain prevents domain members from changing their computer account passwords. If these passwords are weak or compromised, the inability to chan...Rule Medium Severity -
Windows Server 2022 Add workstations to domain user right must only be assigned to the Administrators group on domain controllers.
Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities. Accounts with the "Add workstations to domain" right may add computers to a domain. Thi...Rule Medium Severity -
Windows Server 2022 Deny log on through Remote Desktop Services user right on domain controllers must be configured to prevent unauthenticated access.
Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities. The "Deny log on through Remote Desktop Services" user right defines the accounts that ...Rule Medium Severity -
The password for the krbtgt account on a domain must be reset at least every 180 days.
The krbtgt account acts as a service account for the Kerberos Key Distribution Center (KDC) service. The account and password are created when a domain is created and the password is typically not ...Rule Medium Severity -
Windows Server 2022 local administrator accounts must have their privileged token filtered to prevent elevated privileges from being used over the network on domain-joined member servers.
A compromised local administrator account can provide means for an attacker to move laterally between domain systems. With User Account Control enabled, filtering the privileged token for local ad...Rule Medium Severity -
Windows Server 2022 must restrict unauthenticated Remote Procedure Call (RPC) clients from connecting to the RPC server on domain-joined member servers and standalone or nondomain-joined systems.
Unauthenticated RPC clients may allow anonymous access to sensitive information. Configuring RPC to restrict unauthenticated RPC clients from connecting to the RPC server will prevent anonymous con...Rule Medium Severity -
Windows Server 2022 Access this computer from the network user right must only be assigned to the Administrators and Authenticated Users groups on domain-joined member servers and standalone or nondomain-joined systems.
Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities. Accounts with the "Access this computer from the network" user right may access resourc...Rule Medium Severity -
Windows Server 2022 Deny log on as a batch job user right on domain-joined member servers must be configured to prevent access from highly privileged domain accounts and from unauthenticated access on all systems.
Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities. The "Deny log on as a batch job" user right defines accounts that are prevented from lo...Rule Medium Severity

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
