When writing the policy-based.rules file I had as my first lines several lines
that read as follows:
alert ip any any -> [any,10.10.0.0/24] any
alert tcp any any -> [any,10.10.0.0/24] any
alert udp any any -> [any,10.10.0.0/24] any
While these lines were uncommented, I would get an enormous amount of alerts
from the 10.10.0.0 subnet even though subsequent pass rules told snort to let
pass any and all ip, tcp, and udp traffic on any port. Once I commented out the
lines, the alerts dropped down to 0.
Do I need any alert rules at the beginning of the policy-based.rules file to
specify what subnets, in this case any subnet excluding the 10.10.0.0 subnet,
snort should alert me on? If so, what is the correct syntax?
I did include the -o option in the command syntax. FYI syntax as follows:
/usr/local/bin/snort -i eth0 -c /etc/snort/snort.conf -o
The location of the policy-based.rules file is /etc/snort
Also, I do not seem to be getting any alerts from traffic coming in from the
Internet. Is that normal?
