Deployment
Place the Ethernet TAP on the Ethernet cable in the same location where an Ethernet hub would
be used. The Ethernet tap has the exact same function as the hub, except that one of the ports is
uni-directional and outputs data that is passing over the wire. This is the port that is connected to
CC-NOC’s monitoring interface.

Configure Appliance Home Networks
The CC-NOC that has been selected to handle intrusion detection will detect some signatures
differently depending on whether or not they are incoming or outgoing from the home network.
For this reason, it is important to set up the home network for the device to ensure that the
intrusion detection is as accurate as possible and that the number of false positive alerts is
minimized.
