Test ID:
Title:Checkpoint FW-1 identification

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 allow any connection on the
firewall itself, except for the firewall
protocol, and allow that for trusted sources

If you have a router which performs packet
filtering, then add ACL that disallows the
connection to these ports for unauthorized
