RE: Domain Centric Administration

["Hallam-Baker, Phillip" <[e-mail]>]

Doug,

You are entirely right about the internet crime issues. In my book (to be published in the Fall, Addison Wesley) I mention default deny and domain centric of course but they are not what I would regard as my first line of defense.

The problem we always get to with Internet crime is the 'The problem is X/ no its Y/ no its Z' debate. The problem is X, Y and Z and A through W as well. The idea of the book is to set out a straw man for a comprehensive solution so that instead of having that debate people can instead say 'your solution to X sucks, here is a better one', and I can reply 'thanks, now I can write the second edition'.


The point here is that I want to help people deploy IPv6 even though it is not the very top of my list of priorities and I am not a network routing person (not done work on that layer since my undergraduate thesis and proofs of deadlock freedom for routing protocols).

What I have learned from deploying security is that even though people say that security is their #1 concern, they lie. Their #1 concern is always going to be something else. But security will always top every poll of top 5 priorities because it is everyone's #2 or #3 issue.


We are dealling with very fine tipping points here. 95% right means zero deployment, get it to 96% and suddenly it takes over the world in 18 months. The gap between the Web and gopher or HyperG is very very small. HyperG was in many ways technically superior, certainly the application software was better right up to 1995/6 or so.
