Hi!
Sorry to intervene so late on that subject, I was in holiday.
There is a now quite old paper (1997) that fits exactly with the ideas
that were expressed and I think you should have a look at it:
C.L. Schuba, I.V. Krsul, M.G. Kuhn, E.H. Spafford, A. Sundaram, and D.
Zamboni, "Analysis of a denial of service attack on TCP," in /Proc. IEEE
Symposium on Security and Privacy 1997/, May 4-7, 1997, pp. 208-223.
As far as I know, it was one of the first paper published on the subject
and there are a few proposed solutions with their issues. It includes
the two solutions mentioned at first in the previous mails.
About the establishing "illegitimate connections" case, well it worth
doing when considering that the processing power/memory needed to take
care of the illegitimate connections has more capacity than the backlog
queue can accept half-open connections.
Bye,
Emmanuel
