Packet Sniffing In a Switched Environment
Tom King · 2007
This paper focuses on the threat of packet sniffing in a switched environment, and briefly explores the effect in a non-switched environment. Detail is given on a number of techniques, such as ARP (Address Resolution Protocol) spoofing, which can allow an attacker to eavesdrop on network traffic in a switched environment. Third party tools exist that permit sniffing on a switched network. The result of running some of these tools on an isolated, switched network is presented, and clearly demonstrates that the threat they pose is real and significant.
