This last attack is
known as a SYN flood attack.
There are ways to reduce the impact of SYN flood attacks, but no real
means of prevention without violating the TCP specification. The firewall uses
a shortened timeout on incoming connection requests, a large connection
request queue, and less resources for each pending connection;
this does not prevent SYN floods, but should greatly reduce the impact
of such attacks.

password is compromised, then the firewall can be broken into, but only
if the attack comes from the firewall console itself.
