I am setting up a policy-based rules file to have Snort monitor traffic
coming from the Internet, while allowing
network traffic from the internal network to pass without incident. I want
to provide a blanket pass statement
for the internal network, and I want to verify several things:
1. I don't want, initally, to monitor any traffic going from the 10.1.0.0
network to any TCP/IP port on the server
188.8.131.52. Therefore would the following statements work?
pass ip 10.1.0.0/24 any -> 184.108.40.206 0:65534
pass tcp 10.1.0.0/24 any -> 220.127.116.11 0:65534
pass udp 10.1.0.0/24 any -> 18.104.22.168 0:65534
2. If I want, at a later date, to monitor particular port traffic, do I add
the ports I want to monitor AFTER the
blanket range shown in item 1, or do I add them BEFORE it?
