Description
Users must not be able to override the system policy on wireless remote access connections because this could allow them to establish unauthorized remote access connections. The mobile device itself could provide services to other systems, which is not an acceptable use of the mobile device. Unauthorized remote access connections would expose the mobile device to additional risk, thereby increasing the likelihood of compromise of its confidentiality and integrity. SFR ID: FMT_MOF.1.1(2) #08

Check Text ( C-50773r3_chk )
Note: This validation procedure is identical to the one for KNOX-25-013600. It only needs to be performed once. If it is found compliant on the first check, it is also compliant here. If it is determined to be a finding on the first check, it is also a finding here. Redundant checks are necessary to maintain requirements traceability and provide complete risk management information to the DAAs. This validation procedure is performed on the Samsung Knox Android device only. On the Samsung Knox Android device: 1. Open the application list. 2. Verify the presence of an MDM agent. Note: Verification on the MDM agent is MDM vendor specific. For example, on the Fixmo MDM agent, open the MDM agent, press the Menu button and select "Details". 1. Verify Profile ID is not "NULL". 2. Press the Menu button. 3. Select "Poll Server". 4. Verify no errors are generated in the messages list. On the AirWatch MDM agent: 1. Open the MDM agent. 2. Select "Device Status". 3. Verify "Enrollment Status" is enrolled. If the MDM agent is not present on the Samsung Knox Android device, or if the MDM vendor specific checks do not show the proper value, this is a finding.

This validation procedure is performed on the Samsung Knox Android device only.

On the Samsung Knox Android device:
1. Open the application list.
2. Verify the presence of an MDM agent.
Note: Verification on the MDM agent is MDM vendor specific.

For example, on the Fixmo MDM agent, open the MDM agent, press the Menu button and select "Details".
1. Verify Profile ID is not "NULL".
2. Press the Menu button.
3. Select "Poll Server".
4. Verify no errors are generated in the messages list.

On the AirWatch MDM agent:
1. Open the MDM agent.
2. Select "Device Status".
3. Verify "Enrollment Status" is enrolled.

If the MDM agent is not present on the Samsung Knox Android device, or if the MDM vendor specific checks do not show the proper value, this is a finding.

Configure the OS to allow only the administrator/MDM to disable the screen lock function. On the MDM Console, set the "Max Time to Lock" to the organization-defined value in the "Android Knox Container Password Restrictions" rule.
