Simply not a true statement. I'll give one example as an illustration. User A at IP address 172.16.1.1 connects to a remote host foo.com using telnet by entering "telnet foo.com" from a command prompt which would normally connect to 192.168.1.1 (using RFC 1918 addresses rather than real ones). Evil person B has access to a router that is in the path between user A and the telnet server for foo.com. Evil person B sets up a span port and sniffs traffic to his hearts content....including the telnet session. Note that evil person B is not on the same network segment as either of the endpoints. Obviously, this is a simplified and contrived example that ignores asymetric routing, etc. ------------------------------------------------------------------------------ This List Sponsored by: CenzicConcerned about Web Application Security?
