Check: KNOX-12-110250
Samsung Android 12 with Knox 3.x COBO STIG:
KNOX-12-110250
(in versions v1 r2 through v1 r1)
Title
Samsung Android must allow only the Administrator (management tool) to perform the following management function: install/remove DoD root and intermediate PKI certificates. (Cat II impact)
Discussion
DoD root and intermediate PKI certificates are used to verify the authenticity of PKI certificates of users and web services. If the user is allowed to remove root and intermediate certificates, the user could allow an adversary to falsely sign a certificate in such a way that it could not be detected. Restricting the ability to remove DoD root and intermediate PKI certificates to the Administrator mitigates this risk. SFR ID: FMT_MOF_EXT.1.2 #47
Check Content
Review the configuration to determine if the Samsung Android devices are preventing users from removing DoD root and intermediate PKI certificates. This validation procedure is performed on both the management tool and the Samsung Android device. On the management tool, in the device restrictions, verify that "Config credentials" is set to "Disallow". On the Samsung Android device: 1. Open Settings >> Biometrics and security >> Other security settings >> View security certificates. 2. In the System tab, verify that no listed certificate in the Device can be untrusted. 3. In the User tab, verify that no listed certificate in the Device can be removed. If on the management tool the device "Config credentials" is not set to "Disallow", or on the Samsung Android device a certificate can be untrusted or removed, this is a finding.
Fix Text
Configure the Samsung Android devices to prevent users from removing DoD root and intermediate PKI certificates. On the management tool, in the device restrictions, set "Config credentials" to "Disallow".
