Title

LG Android 6.x must implement the management setting: Install CA certificate (for Work Profile). This requirement is only valid for activation type COPE#2. (Cat II impact)

Discussion

Unauthorized applications pose a variety of risks to DoD information and systems. Digital signature (or public key) technology enables strong assurance of application source and integrity. However, these assurance characteristics are only present when the certificates or public keys used to validate signatures are known and trusted. If an adversary's key is used to validate signatures on applications, the MOS would then trust any code that the adversary signed with its corresponding private key. The impact could include compromise of DoD-sensitive information. Limiting certificates and public keys to those that DoD has approved mitigates this risk. SFR ID: FMT_SMF_EXT.1.1 #45

Check Content

This validation procedure is performed on both the MDM Administration Console and the LG for Android device. On the MDM console, do the following: 1. Ask the MDM administrator to display the list of server authentication certificates in the "Certificate Configuration" rule for Work Profile. 2. Verify the CA certificates are present. 3. Verify the policy has been assigned to all groups. On the LG for Android device: 1. Navigate to Settings >> General >> Security (or Fingerprints & security) >> Certificate management >> Trusted credentials. 2. Select the "User" tab. 3. Verify the presence of the CA certificates under "Work" for Activation Type COPE#2. If on the MDM console the CA certificates are not present in the MDM Console certificate configuration or on the device the CA certificates are not listed under the "User" tab, this is a finding.

Fix Text

Configure the mobile operating system to install CA certificates on the device. On the MDM Console, add the CA certificates to the "Certificate Configuration" rule for the Work Profile.
