The Samsung KNOX for Android platform must be configured to Disable Admin Remove.

Overview

Description
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
