Spyware

[Matt Stern <sternm () comprehensive com>]

Hello all:

I was just wondering if spyware sends its answers "back home" on any 
particular TCP or UDP port.  If so, then couldn't I doubly safeguard the 
LAN (after trying to keep all the spyware off the workstations) by 
disallowing outbound communications via the firewall, for those ports? 
Or conversely, instead of allowing all outbound traffic, only allow the 
usual ports, such as 80, 443, 23, etc?

Thanks.
