Kim, If you use the security servers, they will provide this for you. Also protocols defined in inspect will (atleast to a certain degree) do this. All other protocols that are defined by a tcp/udp port will not do this. ZoneAlarm OTOH is a personal firewall, which works in a totally different way that fw1. As a personal firewall it doesn't care about ports, but rather about applications. It stores each applications identity as a MD5 hash, so if you allow an application to access the internet, Zonealarm will notice if the application change or the executable is replaced.

Lohse Sent: Saturday, July 07, 2001 20:44 To: [email protected] Subject: [FW1] Trojans & spyware imitating alowed trafic Hey all' I was wondering if anybody knows how to prevent programs such as Trojans and spy ware from imitating allowed traffic such as FTP by using the same port? I know that ZoneLabs' free ZoneAlarm prevents this by cryptographically certifying the identity of executable programs. But how do I do some thing similar with FW-1? -------------------------------- Kim S.
