Description
DoD root and intermediate PKI certificates are used to verify the authenticity of PKI certificates of users and web services. If the root and intermediate certificates are not available, an adversary could falsely sign a certificate in such a way that it could not be detected. Providing access to the DoD root and intermediate PKI certificates greatly diminishes the risk of this attack. SFR ID: FMT_SMF.1.1 #13

Check Text ( C-56637r1_chk )
This validation procedure is performed on both the MDM Administration Console and the Samsung Knox for Android device. The current DoD root and intermediate PKI certificates may be obtained in self-extracting zip files at http://iase.disa.mil/pki-pke (for NIPRNet) or http://iase.rel.disa.smil.mil/pki-pke/function_pages/tools.html (for SIPRNet). Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the list of server authentication certificates in the "Android Certificate Configuration" rule. 2. Verify the DoD root and intermediate PKI certificates are present. On the Samsung Knox for Android device: 1. Open the device settings. 2. Select "Security". 3. Select "Trusted Credentials". 4. Review Certificate Authorities listed under the "System" and "User" tabs. 5. Verify the presence of the DoD root and intermediate certificates. If the DoD root and intermediate certificates are not present in the MDM Console whitelist or on the device, this is a finding.
