Re: How to turn off a rule

[JJC <cummingsj () gmail com>]

As a quick note, suppressing an entire SID is pretty inefficient.. it only
suppresses the alert form being recorded, the rule itself still loads into
memory and traffic is still evaluated against it.  In almost every case
where you are generically suppressing a SID, you should instead be
disabling the SID.
