Multi-Homed / Ad hoc Network

A Genian Agent can immediately detect a multi-homed configuration and Ad hoc network connections in a variety of ways. If a computer having more than one IP address configured connects to more than one network and one of them is not on the trusted network, then Genian NAC designates the Node as a critical one.

This anomaly definition requires installing an Agent on the endpoint and enabling an Agent Action In the node policy.

See: Controlling Network Interface.
