Hello: I am going to upgrade some servers to Windows 2003. In the past I have used Norton Internet Security as a firewall on my server. With the situation as it is I don't think a hardware firewall would be a prudent choice for our particular situation because the main building and network closets we occupy are shared by several departments and the organizations that will use the fileservers are in several locations throughout campus. Additionally with the bandwidth required, a hardware firewall can be very expensive. Does anybody out there use a software firewall / IPS or IDS to protect their Windows 2000 or 2003 servers? If you do use a software firewall for w2k or w2003 servers: 1. What do you use? 2. Can you copy the firewall rules for backup or use on another machine? 3. Have you used any tools such as performance monitor to determine the software firewall's affect upon system resources such as cpu time and memory? 4. Does this require a yearly subscription?
