Hi, Since we had lots of interesting discussions on the subject in the hall at NANOG 28 and people asked for the slides, here they are :) DDoS Mitigation and Analysis at the Infrastructure Level [and router forensics] (PPT&PDF) http://www.securite.org/presentations/ddos/ And since we have two talks on BGP (in)security and a panel on S-BGP/soBGP, an "older" presentation on the subject: IP Backbone Security (PPT&PDF) http://www.securite.org/presentations/secip/ And BTW, I haven't seen a network being that actively scanned by various hosts for quite some time now. Maybe we'll soon see a PR from [put your favorite group's name here]: "thanks to NANOG all your routers/networks are belong to us" ;-)) Nico. -- Nicolas FISCHBACH (nico@securite.org) <http://www.securite.org/nico/> Senior Manager - IP Engineering/Security - COLT Telecom Securite.Org Team <http://www.securite.org/>
