Simultaneous connections to the internet or a Windows domain must be limited.
An XCCDF Rule
Description
Multiple network connections can provide additional attack vectors to a system and must be limited. The "Minimize the number of simultaneous connections to the Internet or a Windows Domain" setting prevents systems from automatically establishing multiple connections. When both wired and wireless connections are available, for example, the less preferred connection (typically wireless) will be disconnected.
