The Windows 2012 DNS Server must only allow the use of an approved DoD PKI-established certificate authorities for verification of the establishment of protected transactions.
Medium Severity
<VulnDiscussion>Untrusted Certificate Authorities (CA) can issue certificates, but they 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 2012 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 certification authority (CA). Refer to the U_Windows_Domain_Name_Service_2012_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>
