Network Taps
Network Taps were developed to address perhaps the most prevalent issue with network intrusion detection deployments -- how to connect the IDS to the network. The basis of the issue is that the switches and routers that serve as connection points for intrusion detection systems are “owned” in the enterprise by the IT or networking group, not the security group. This leaves the security group soliciting permanent access to the spanning port of the switch or router. The spanning ports are scarce, and expensive, so the IT group is more than hesitant to relinquish them. Following closely behind in the issues is the fact that the definition of “spanning” is loosely held by the router and switch manufacturers. See the Switch Port Mirroring Page for the syntax for configuring various switches.
The typical solution to avoid these issues was to add a switch or hub to the network in order to support the IDS, although the most efficient method is arguably the Network Tap.
