Information
You can use this procedure to controls user's ability to install and configure a Network Bridge.
The recommended state for this setting is: Enabled.
Rationale:
The Network Bridge setting, if enabled, allows users to create a Layer 2 Media Access Control (MAC) bridge, enabling them to connect two or more physical network segments together. A Network Bridge thus allows a computer that has connections to two different networks to share data between those networks.
In an enterprise managed environment, where there is a need to control network traffic to only authorized paths, allowing users to create a Network Bridge increases the risk and attack surface from the bridged network.
Impact:
Users cannot create or configure a Network Bridge.
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 Configuration profiles
Click Create profile
Select the platform (Windows 10 and later)
Select the profile (Administrative Templates)
Click Create
Enter a Name
Click Next
Configure the following Setting
Path: Computer Configuration/Network/Network Connections
Setting Name: Prohibit installation and configuration of Network Bridge on your DNS domain network
Configuration: 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. (Users are able create and modify the configuration of Network Bridges. Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure.)
