Awesome talk! I especially like how you walked through your approach and provide scapy samples - very cool.

Doesn't seem like it...

There are definitely some options here, at least on the wired side. However, Enno had a great point in his preso about being realistic with operational complexity. That remains a challenge.

Interested in what everyone thinks. IMHO, short term best options are working with major vendors at the access layer and for security solutions. At the access layer (Ethernet switches, Wireless controllers, Access points) and for firewalls push for strong controls for extensions headers and fragmentation. For IDS/IPS push for good detection. Could an IPS do prevention without being susceptible to DoS?
So the question is, what are the best practices to push for? Are the RFCs reasonable and change the shoulds to musts (in access layer/firewalls)? I guess the other thing I'm wondering is if ASICs/FPGAs can either cope with or be enhanced to cope with this at high speed.
Other thing is perhaps coming up with a standard "fuzzing" framework for access layer/security tools to accelerate "stack maturity."
What do you think?
