Oh, I almost forgot:
I submitted a abstract, outline, and bio to Jeff Moss, organizer of The Blackhat Briefings and Defcon for a presentation I'd like to deliver at this year's Blackhat: Las Vegas in July. It's titled "The Impact of P2P on Security in the Enterprise" and will attack the hard questions facing P2P and decentralized applications inside the space of a secure enterprise network. I think there's way too little of this sort of discourse going on in either the P2P community (where I see mostly a lot of talk of ad hoc NAT tunneling, among other worrying trends) or in the security community (where the bulk of P2P seems to be about Napster and how to stop it from raping all your bandwidth). This is dangerous. It's also dumb. I'm proposing to talk about these issues not only to the people developing the systems, but also to the security administrators whose job it is to make sure their networks stay secure. Hopefully this presentation will get the ball rolling.
If you think this sounds like a worthwhile presentation, and you will be attending Blackhat in Vegas this year, please mail Jeff and ask him to consider the presentation for inclusion into the schedule. I'm working on the PowerPoint that will be shown at the conference right up to the June 1st deadline. If you have comments or suggestions, please mail me.
Brief credentials: I work as a Research Scientist for OpenCola and also serve as the Chief Security Architect. OpenCola is a pre-IPO startup company working to provide distributed computing infrastructure (DCI) solutions to the marketplace (as in P2P and decentralized apps). Previous to OpenCola, I worked in Research for Viasec Limited, a crypto software development firm based in Ireland (now out of business).
Enough self-promotion. Sorry about that.
