Paul 'Tony' Watson Interviewed

An anonymous reader writes "Whitedust is running an interview with Paul Watson. Watson, who discovered a flaw in TCP/IP that could allow attackers to reset connections last year, made a splash with the media. He talks about how he got his start in computer security, as part of the early warez scene, his work in the Air Force and the US Government, and his current projects.

      Yes. What's new is that Paul realised that the sequence number doesn't need to be brute forced from all 2^32 combinations - it only needs to fall within the current window. That makes the attack much more practical.

This guy probably deserves the credit for creating a media frenzy about this problem, but not much else.

      It really has bugged me, in the past, that all the popular operating systems assign outgoing ports sequentially. This especially causes problems with net-booted systems, because if the system gets interrupted part-way into the initial network transfer, the routers get really confused because on retry, all the source port and sequence numbers are the same! I've had problems with this before (I design software for embedded systems), and I think this is when I first "discovered", like this guy did, how relatively easy it is to perform TCP RST attacks under some circumstances.

    After seeing him point out that the government came to regard hackers as such a major threat, I couldn't help but think that our government brings on most of its own problems. The hiring and firing practices and I suppose the procurement processes are also completely fucked up and need to be modernized.

    Our government will put people getting $50-$60K into a jet that costs $2B to build and that can carry very large nuclear payloads. They nearly crippled our navy's ability to wage war on other naval power through the SmartShip program, all because they wanted to save on the cost of a sysadmin's salary.

    I'm a libertarian by persuasion and I want the government buying the very best and being competitive in its core competencies. I want them to hire the best and brightest, and pay them accordingly because it's cheaper to pay someone an above fair market wage to get the best talent than to have someone do billions of damage to your country's networks. Saving money should be secondary to the government getting everything it needs to carry out its core missions.

    Someone who brings a tremendous wealth of networking experience should be elligible for a six digit salary starting out, just as they would in the private sector. I have no problem paying someone who's extremely good at computer security several hundred thousand dollars to do federal network security because as I said, it's cheaper to pay for good people who'll get the job done right.
