Make sure Telnet, finger and SNMP are blocked from the Internet. Also, if using security servers, modify the banenrs from within the FW GUI to hide the fact that you're running a Checkpoint firewall. The defaults are probably well known amongst the hacking community. Telnet is the most common way of finding out what version the host is. The telnet banner can be stripped if necessary (eg modify inetd.conf under UNIX to start telnetd with a -h). ----- Original Message ----- From: Fernandes, Andy (ANDF) <[email protected]> To: <[email protected]> Sent: 21 March 2001 20:40 Subject: [FW1] How do you prevent the Firewal operating system from being identified? > > Hello all: > > I have been told that it is possible to identify a Checkpoint Firewall's > operating system type, build and version type from the outside by examining > banners and using various fingerprinting techniques.
