The VPN Gateway providing authentication intermediary services must only accept end entity certificates (user or machine) issued by DOD PKI or DOD-approved PKI Certification Authorities (CAs) for the establishment of VPN sessions.
Medium Severity
<VulnDiscussion>Untrusted Certificate Authorities (CAs) 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 TLS certificates. Reliance on CAs for the establishment of secure sessions includes, for example, the use of Internet Key Exchange (IKE). This requirement focuses on communications protection for the application session rather than for the network packet. VPN gateways that perform these functions must be able to identify which session identifiers were generated when the sessions were established. Certificates for both user and machines must be validated.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
