[Snort-users] Why so many default disabled rules?

The more rules you enable the more resource-intensive the snort process is. :)  Also, some rules have a higher false positive rate than others or are more useful in some environments than others.

Basically Snort has to make an educated guess as to which rules need to be turned on, and it's up to you to determine if that guess is correct for your environment.

I am curious as to why the Snort rules ship with so many of them disabled/commented out by default.

It seems the default set is ~4,000. But if using the option to enable /all/ rules in Oinkmaster it comes out with ~20,000. I get Registered User Release rules, not the Subscriber Release rules.
