Vulnerability discussion

Security-related parameters are those parameters impacting the security state of the system and include parameters related to the implementation of other IA controls. If these controls are not implemented, the system may be vulnerable to a variety of attacks. The use of an MDM allows an organization to assign values to security-related parameters across all the devices it manages. This provides assurance that the required mobile OS security controls are being enforced and that the device user or an adversary has not modified or disabled the controls. It also greatly increases efficiency and manageability of devices in a large-scale environment relative to an environment in which each device must be configured separately. For these reasons, a user must not be allowed to remove the MDM from the device.SFR ID: FMT_SMF_EXT.1.1 #45

Check content

This validation procedure is performed on both the MDM Administration Console and the Samsung KNOX for Android device. Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the "Allow Admin Remove" settings in the "Android Restrictions" rule. 2. Verify the value is disabled. On the Samsung KNOX for Android device: 1. Open the device settings. 2. Select "Lock screen and security". 3. Select "Other security settings". 4. Select "Device administrators". 5. Verify the enterprise MDM agent is on and cannot be turned off. If the "Allow Admin Remove" setting is enabled, or if the MDM agent on the device can be turned off, this is a finding.

Fix text

Configure the operating system to disable admin removal by the user. On the MDM Administration Console, disable the "Allow Admin Remove" setting in the "Android Restrictions" rule.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
