Re: Packet anonymity is the problem?

You make two assumptions:

1. denial of service requires compromised hosts
2. good code prevents hosts from being compromised

I agree that without zombies launching a significant DoS is much more
difficult, but it can still be done. Also, while many hosts run insecure
software, the biggest security vulnerability in most systems is the
finger resting on the left mouse button.

Prior to Windows I would have agreed with you.  However, with the advent
of Windows, I think insecure software has surpassed the user as a source
of problems.  This is not based on a belief that users have gotten any
better, but, rather that software is significantly worse.

Also, waiting for others to clean up their act to be safe isn't usually
the most fruitful approach.

This is very true.  However, education and encouragement of others to fix
their insecure systems is a worth-while endeavor, and, the reality remains
that if we could find a way to solve that issue, it would significantly
reduce today's DDOS and SPAM environment.

   While it can sound a bit theorical (to hope that the "others" will
   run secure code), as the vast majority of users run OSs from one
   particular (major) vendor, an amelioration of said family of OSs
   would certainly benefit to all. Just think about all the recent
   network havocs caused by worms propagating on one OS platform ...
I'm not all that interested in plugging individual security holes. (Not
saying this isn't important, but to the degree this is solvable things
are moving in the right direction.) I'm much more interested in shutting
up hosts after they've been compromised. This is something we absolutely,
positively need to get a handle on.

I think both efforts are necessary and worthy.
