The ALG must only allow the use of DoD PKI-established certificate authorities for verification of the establishment of protected sessions.

Description
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. This requirement focuses on communications protection for the application session rather than for the network packet.

Check Text ( C-SRG-NET-000355-ALG-000117_chk )
Verify the ALG allows the use of DoD PKI-established certificate authorities for verification of the establishment of protected sessions. If the ALG uses non-DoD PKI-established certificate authorities for verification of the establishment of protected sessions, this is a finding.

Fix Text (F-SRG-NET-000355-ALG-000117_fix)
Configure ALG to only allow the use of DoD PKI-established certificate authorities for verification of the establishment of protected sessions.
