Re: proper metadata use?

sure, I just thought maybe this wasn't the proper metadata tag for
these rules, if people started to leverage this to build drop
rule-sets using pulled-pork, oinkmaster or whatever.

Will, certainly a valid concern....

Currently pulledpork does not set rules automatically to a "drop" state...
But rather alert only... The user must specify to pulledpork what rules that
they want to set as drop, using the dropsid configuration option...

Is the metadata policy for all of these rules correct?  If people
start using pulled-pork for policy drop stuff... or maybe I'm
mis-understanding the meaning of this metadata tag.

grep "security-ips drop" *.rules | grep "flowbits\:\s*noalert"

Looks like it would end up in a lot of traffic that is being used for
protocol decode.  It is generally a bad idea to mix drop and
flowbits:noalert as valid traffic ends up getting dropped and the
users have no idea why.  Just my 2 cents....
