STIGQter: STIG Summary: Microsoft Windows Server 2019 Security Technical Implementation Guide Version: 2 Release: 2 Benchmark Date: 04 May 2021:

Windows Server 2019 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.

Fix Recommendation

Configure NSA-approved (Type 1) cryptography to protect the directory data in transit for directory service implementations at a classified confidentiality level that transfer replication data through a network cleared to a lower level than the data.

Check Contents

This applies to domain controllers. It is NA for other systems.

Review the organization network diagram(s) or documentation to determine the level of classification for the network(s) over which replication data is transmitted.

Determine the classification level of the Windows domain controller.

If the classification level of the Windows domain controller is higher than the level of the networks, review the organization network diagram(s) and directory implementation documentation to determine if NSA-approved encryption is used to protect the replication network traffic.

If the classification level of the Windows domain controller is higher than the level of the network traversed and NSA-approved encryption is not used, this is a finding.
