LAN switch security: What hackers know about your switches with Cisco's Christopher Paggen: Contrary to popular belief, Ethernet switches are not inherently secure. Security vulnerabilities exist all over the place. Did you know that there are vulnerabilities in the control plane protocols like STP and CDP? There are holes in the data plane protocols too. Christopher Paggen is prepared to tell you how to avoid these problems. Paggen is a technical marketing engineer for Cisco focusing on high-end firewalls. Join us for a live chat Tuesday Nov. 13 from 2 p.m. to 3 p.m. EST, where you can ask him about configuring and securing switches, firewalls or anything else you want to talk about.
