Hi Richard.

I think we are on the same side here, but none the less:

Then we disagree on what "inherent" means. Moving on...

Nor did I say this. I just said that MS could go a very long way towards
a more secure product by taking some simple steps. Obviously there are a
lot of other things they could and should do, but those three things
would be a start.

You were talking about compartmentalising things - how can an
application know whether an inbound packet is spoofed? And if it could,
why build that sort of smarts into a thousand applications with a
thousand authors? And why build policy on an application by application
basis? And force everyone who installs a program to understand and
inplement that policy separately? Far better to put that policy where it
belongs - on the network interface (or *slightly* upstream from the
network interface, as with a firewall).
