What benefit does locking the glass doors into a bank add to having time-locked vault? Defense in depth.

The vault and the locked glass doors defend against entirely different things. Same doesn’t really apply for ssh keys and port knocking.

A port knock is just a clear password :/

I much prefer restricting port 22 to a few ip and disable passwords

Not with single packet authentication from fwknop

fwknop has a cache to prevent replay attacks, that plus the fact the packets are only valid for a certain length of time pretty much thwarts this. Remember, fwknop is _in addition_ to your existing security practices, it is not the only "password."

"A port knock is just a clear password"

It is only clear to the routers in your traceroute ... third party attackers cannot snoop on this traffic.

Right, exactly like a clear text password.
