ARP poisoning by a hacker is probably the worst attack your LAN could suffer because it's extremely sneaky, very efficient and all too easy to perform. But there are two ways to protect yourself from an ARP spoofing/posioning attack, according to Christoper Paggen, author of LAN Switch Security: What Hackers Know About Your Switches, published by Cisco Press.
The options for your defense are to either monitor suspicious ARP traffic on a machine connected to the LAN (using ARPWatch for instance, a free Linux utility) or rely on the switch's built-in security mechanism, Paggen told attendees to Network World's live online text chat with the author on Thursday.
During the one-hour chat, Paggen covered a range of security topics, including P2P security issues, wireless LAN threats, and protecting against multicast storms.
