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_EXT.1.1 #47

Details

Check Text ( C-93237r2_chk )
Review device configuration settings to confirm that the DoD root and intermediate PKI certificates are installed.

This procedure is performed on both the MDM Administration console and the Samsung 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).

On the MDM console, for the device, in the "Knox certificate" group, verify that the DoD root and intermediate PKI certificates are listed.

On the Samsung Android device, do the following:
1. Open Settings.
2. Tap "Biometrics and security".
3. Tap "Other security settings".
4. Tap "View security certificates".
5. Verify the DoD root and intermediate certificates are listed under the "Personal" list in both the "System" and "User" tabs.

If on the MDM console the DoD root and intermediate certificates are not listed in the "Knox certificate" group, or on the Samsung Android device "View security certificates" does not list the DoD root and intermediate certificates, this is a finding.
