Raven Alder (raven@oneeyedcrow.net) is a somewhat cynical security geek with a focus on backbone network engineering. Her recent work on penetration testing routing and switching infrastructure has rocked the ISP boat a bit, but she believes that a well-tested backbone is more likely to be a secure backbone. She has coauthored books on the security tools Snort and Nessus and has spoken at many conferences, including previous Black Hat conferences, Linux World Expo, and DefCon. For her next trick, she intends to test implementations of cryptography on critical infrastructure devices.
