Receive-only UTP cables and Network Taps
Diego Gonzalez Gomez · 2006
One of the disadvantages of a sniffer is that it may be detected by other hosts. There are a number of methods to avoid detection, one being configuring the sniffer without an IP address. But none of them are as effective as the use of receive-only (sniffing) cables. These cables allow a sniffer to watch network traffic without being detected. Therefore they prove very useful in environments with Intrusion Detection Systems (IDS) or honeypot technologies (such as Honeynets).
