Defcon

The twenty-second DEFCON took over Las Vegas last week, and brought many interesting and notable speakers. I took a few notes from the talks that stood out to me, and I'm passing them along here.

Paul Vixie, Internet pioneer and DNS expert. Vixie spoke about his DNSDB project for accumulating global DNS resource records in a passive fashion, and making this information available to researchers and security product vendors. He also spoke about his DNS firewall for shielding users from malicious throwaway domain names.
