18.5.21.1 Ensure 'Prohibit connection to non-domain networks when connected to domain authenticated network' is set to 'Enabled'
Information
This policy setting prevents computers from connecting to both a domain based network and a non-domain based network at the same time.The recommended state for this setting is: Enabled.
Rationale:
The potential concern is that a user would unknowingly allow network traffic to flow between the insecure public network and the enterprise managed network.
Impact:
The computer responds to automatic and manual network connection attempts based on the following circumstances:
Automatic connection attempts - When the computer is already connected to a domain based network, all automatic connection attempts to non-domain networks are blocked. - When the computer is already connected to a non-domain based network, automatic connection attempts to domain based networks are blocked.
Manual connection attempts - When the computer is already connected to either a non-domain based network or a domain based network over media other than Ethernet, and a user attempts to create a manual connection to an additional network in violation of this policy setting, the existing network connection is disconnected and the manual connection is allowed. - When the computer is already connected to either a non-domain based network or a domain based network over Ethernet, and a user attempts to create a manual connection to an additional network in violation of this policy setting, the existing Ethernet connection is maintained and the manual connection attempt is blocked.
Solution
To establish the recommended configuration, set the following Device Configuration Policy to Enabled:To access the Device Configuration Policy from the Intune Home page:
Click Devices

Click Next
Configure the following Setting
Path: Computer Configuration/Network/Windows Connection Manager
Setting Name: Prohibit connection to non-domain networks when connected to domain authenticated network
Setting: Enabled
Select OK
Continue through the Wizard to complete the creation of the profile (profile assignments, applicability etc.)
Note: More than one configuration setting from each of the Configuration profiles (ex: Administrative Templates, Custom etc.) can be added to each Device Configuration Policy.
Default Value:
Disabled. (Connections to both domain and non-domain networks are simultaneously allowed.)
