While most of XP SP2 properly addresses the real issues - how to keep the
bad guys out, part of SP2 is a feeble attempt to mitigate the effects of
malware after it has arrived. Re: outbound rate connection queue
limiting - Even without raw sockets, it is trivial to fill the pipe with TCP
Syn's to one or more addresses, albeit with a real source IP. (Note to MS:
by the time malware has ben installed, it's too late; the horse is already
out of the barn!)
Since the GRC.com attack 2 years ago, even average ISPs put filters in
place to prevent IP address spoofing. I saw one piece of windows malware
about 2 years ago that used spoofed source IPs, but none recently.
Re: no TCP outbound raw sockets; this disables functionality like Win32
TCPtraceroute. Sometimes that is the only way to track network connectivity
issues. As you note, the only solution is to run a system other than XP
SP2.
