ARP Poisoning – I Read Your Email

by @ 7:24 am. Filed under freebies, General Linux, security

Alrighty, folks. I gave a presentation at Utah Valley State College last night about a network security issue called ARP poisoning. It is the ability to hijack any computer’s connection on a local area network. The concept is that you force all traffic going to and from that machine through your own computer. You are then able to filter through that traffic and determine what the user is doing. It is possible to view passwords, and even change traffic as it goes through your computer. Even if they are on a secure website. It’s a fairly common method of attack, and is something to watch out for. I have compiled my notes into an article in the form of a 4-page PDF. If you want to take a look at how ARP Poisoning works, view the PDF here.

    One legitimate use of ARP Poisoning is when enforcing NAC on your network. That is exactly what the open source NAC tool Packetfence can do.
