"Happy holidays! Your Web server just died! I use the
word 'try' very deliberately in my title. The truth of the matter
is that there isn't a damn thing you can do that will stop a
serious distributed denial of service (DDoS) attack. There are
though some ways to try to deal with them.
"Mind you, there is actually is a way that would put an end to
most DDoS attacks. It requires that all Windows-based botnets be
ripped out by the roots. Too bad, that's not going to happen.
"Windows is insecure by design and used by hundreds of millions
and many of those users wouldn't know an anti-virus program from
Angry Birds. Millions of Windows computers, including maybe yours,
are slave labor in one of the various botnets."
