The Windows DNS Server must use an approved DOD PKI certificate authority.
Medium Severity
<VulnDiscussion>Untrusted certificate authorities (CA) can issue certificates, but the certificates may be issued by organizations or individuals that seek to compromise DOD systems or by organizations with insufficient security controls. If the CA used for verifying the certificate is not a DOD-approved CA, trust of this CA has not been established. The DOD will only accept PKI certificates obtained from a DOD-approved internal or external certificate authority. Reliance on CAs for the establishment of secure sessions includes, for example, the use of SSL/TLS certificates. TSIG and SIG(0) are not configurable in Windows DNS Server. To meet the requirement for authentication between Windows DNS Servers, IPsec must be implemented between the Windows DNS Servers. Note: If multiple certificates from the same CA are present on the DNS server, IPsec authentication might fail due to an incorrect certificate being chosen. For this purpose, an Active Directory Certificate Services (AD CS) role must be installed and configured as an Enterprise certificate authority (CA). Refer to the Microsoft Windows Server DNS Overview.pdf for references on deploying certificates for this procedure.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
