I suggest reading the story of the DDoS attacks on Gibson Research's site
(grc.com)
It is enlightening and frightening.
Thanks,

That seems to say that in no case should one risk
any resource of critical value by putting it
on the web because eleven men so inclined can
always do it harm and this isn't a cost vs
benefit issue.
As I review the material I find that while there are
some means for detecting an attack and mitigating it,
and others for restricting its effect such as
limiting bandwidth available for certain operations,
the overwhelming majority of defense in in the
social behavior of those outside one's own control,
that is, ensuring a system cannot be used to host
an attack. Defenses against it is not credible.
It is as if the defender is always in the position
of having stubs for arms against tall and lanky
attackers; that is, it is an inherently unfair fight.
Is that really the case? I read that Microsoft
was able to defend their servers this time
although SCO could not.

The DDoS attack, which is the serious kind, was summed up by Jonathan
Swift as long ago as 1724 thus (emphasis added):
It is true, indeed, that, within the memory of man, the
parliaments of England have sometimes assumed the power of
binding this kingdom [Ireland] by laws enacted there; wherein
they were at first openly opposed (as far as truth, reason,
and
justice are capable of opposing) by the famous Mr. Molyneux,
an English gentleman born here, as well as by several of the
greatest patriots and best whigs in England; but the love and
torrent of power prevailed.
Indeed the arguments on both sides were invincible. For, in
reason, all government without the consent of the governed, is
the very definition of slavery: but, in fact, *eleven men well
armed will certainly subdue one single man in his shirt*. But
I have done; for those who have used power to cramp liberty,
have gone so far as to resent even the liberty of complaining:
although a man upon the rack was never known to be refused the
liberty of roaring as loud as he thought fit.
Historical note: it was on this precedent that the American colonies
founded
their claim not to be governed by the English Parliament; they gave
evidence
of
their refusal by dumping taxable tea into Boston Harbor.
