Windows Bridge Network Connection

Description

This test verifies that the endpoint attempting to connect to the network does not have a bridged
network connection present. A bridged network connection allows the connecting endpoint to
transparently send traffic to and from another network. An example use of this type of connection
would be to bridge a high-speed cellular network connection in and out of the local network. A bridged
network connection poses a significant security risk.

Test Properties

Any endpoint which has a Windows bridge Network Connection will fail this test.

How Does this Affect Me?

Using network bridges can be useful in some environments; however, they also create a security risk.

What Do I Need to Do?
