Vulnerability Assessment Details
Acertains if the remote host is a FW/1
Detailed Explanation for this Vulnerability Assessment
The remote host has the three tcp ports 256, 257 and 258
It's very likely that this host is a Checkpoint Firewall/1.
Letting attackers know that you are running FW/1 will
help them to focus their attack or will make them
change their strategy.
You should not let them know such information.
Solution : do not permit any connection on the
firewall itself, except for the firewall
protocol, and permit that for trusted sources
If you have a router which performs packet
filtering, then add ACL that dispermits the
connection to these ports for unauthorized
