The Infoblox system must only allow the use of DoW PKI-established certificate authorities for verification of the establishment of protected transactions.

Untrusted Certificate Authorities (CA) can issue certificates, but they may be issued by organizations or individuals that seek to compromise DoW systems or by organizations with insufficient security controls. If the CA used for verifying the certificate is not a DoW-approved CA, trust of this CA has not been established.

The DoW will only accept PKI certificates obtained from a DoW-approved internal or external certificate authority. Reliance on CAs for the establishment of secure sessions includes, for example, the use of SSL/TLS certificates.

SIG(0) relies on PKI-based authentication, so if SIG(0) is being used, this requirement is applicable.

Verify Infoblox is configured to use DoW PKI-established certificate authorities for verification of the establishment of protected transactions.

1. Navigate to Infoblox Grid >> Grid Manager tab. 2. Select the "Certificates" dropdown from the toolbar on right. 3. Select "Manage CA Certificates" from menu. 4. Verify information for uploaded certificates are from DoW PKI-established certificate authorities and are valid.

If certificates are used that have not been issued by a DoW Certificate Authority (CA), or are no longer valid, this is a finding.

1. Navigate to Infoblox Grid >> Grid Manager tab. 2. Select the "Certificates" dropdown from the toolbar on right. 3. Select "Manage CA Certificates" from menu. 4. Delete all uploaded certificates that are not from DoW PKI-established certificate authorities.
