See the bugtraq archives or the www.securityfocus.com library for some
analyses of the off-the-shelf DDoS tools out there. There's really nothing
interesting or sophisticated about their effects - the design of the tools
themselves and how they can and cannot be stopped is more interesting.

I guess the most important point to make about security is to make sure
you know what you're doing - don't just leave it at the "well, it's
working" stage, or be satisfied if some junior systems guy takes a pass
over your webserver. *So many* e-commerce sites out there are insecure,
usually because of unaudited systems and poor default settings, or lack of
understanding of the technology and how not to use it, and it's putting
their business, and their customer's money, at risk.

The crypto-gram newsletters (www.counterpane.com) and the RISKS digests
(http://www.CSL.sri.com/risksinfo.html) are good general resources for the
kinds of security pitfalls people make (the former is more focussed on
cryptography, as the name suggests).
