Title

Google Android 16 must allow only the administrator (EMM) to install/remove DoW root and intermediate PKI certificates.

Control

Review the device configuration to confirm that the user is unable to remove DoW root and intermediate PKI certificates. On the EMM console: 1. Open "Set user restrictions". 2. Verify that "Disallow config credentials" is toggled to "ON". On the Google Android 16 device: 1. Open Settings. 2. Tap "Security & privacy". 3. Tap "More security & privacy". 4. Tap "Encryption & credentials". 5. Tap "Trusted credentials". 6. Verify that the user is unable to untrust or remove any work certificates. If on the Google Android 16 device the user is able to remove certificates, this is a finding.

Discussion

DoW 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 DoW root and intermediate PKI certificates to the administrator mitigates this risk. SFR ID: FMT_MOF_EXT.1.2 #47
