Checkpoint FW-1 identification |
||
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 open. 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 only. If you have a router which performs packet filtering, then add ACL that dispermits the connection to these ports for unauthorized systems.
