Well I am very interested to know all attacks that may be ocurring but
network performance is our main concern.
This box is a commercial web app that stream digital media so it must
have the best network speed it can.
Let say only port 80 is open.
Which of the two would run faster
a) Smort with all rules loaded
b) Smort with only port 80 rules loaded.
I tend to think it makes no difference. If port 80 is not being used
snort will not apply those rules.
Am I correct?
Depends on what your're looking for. I run some snort sensors "wide
open" in order to monitor and profile all the attacks that are occuring.
In other cases, only selected rules are enabled.
