Check Contents

Review the configuration to determine if the Samsung Android devices are disabling Trust Agents.

This validation procedure is performed on both the management tool and the Samsung Android device.

On the management tool, in the device restrictions, verify "Trust Agents" are set to "Disable".

On the Samsung Android device:
1. Open Settings >> Security and privacy >> More security settings >> Trust agents.
2. Verify all listed Trust Agents are disabled and cannot be enabled. If a Trust Agent is not disabled in the list, verify for that Trust Agent, all of its listed Trustlets are disabled and cannot be enabled.

If on the management tool "Trust Agents" are not set to "Disable", or on the Samsung Android device a "Trust Agent" or "Trustlet" can be enabled, this is a finding.

Note: If the management tool has been correctly configured but a Trust Agent is still enabled, configure the "List of approved apps listed in managed Google Play" to disable it; refer to KNOX-16-005500.

Exception: Trust Agents may be used if the authorizing official (AO) allows a screen lock timeout after four hours (or more) of inactivity. This may be applicable to tactical use case.
