Have a look at this article:
I believe that it goes over some of the problems of traditional
port-knocking and provides info on how SPA resolves the issue.

Subject: Port-Knocking vulnerabilities?
so I read this thread about port-knocking (altough called
firewalls"). I'd never heard of that and found that to be an very
interesting mechanism. Now I just keep wondering, what an attacker
possibly do to intrude system secured in such a way. So there are
open ports at all, also, there's no way the attacker could access
computer physically or via social engineering. The attacker knows
knock-server is running and that there's some daemon waiting to
accessible (what ever that may be).
What could a attacker do to somehow get access to that machine?
can I secure that machine from that kind of attacks.
