|

used to service outside network connections and dial-in lines. The idea is
|
|||
|
|
to protect a cluster of more loosely administered machines hidden behind it
|
|||
|
|
from <a href="../C/cracker.html"><i class="glossterm">cracker</i></a>s. The typical firewall is an
|
|||
|
|
inexpensive micro-based Unix box kept clean of critical data, with a bunch
|
|||
|
|
of modems and public network ports on it but just one carefully watched
|
|||
|
|
connection back to the rest of the cluster. The special precautions may
|
|||
|
|
include threat monitoring, callback, and even a complete
