Default rule set

Firstly, thank you all for the info, it has been very helpful.

I have configured my pulled pork with the security setting and it seems to be working well.  Now, as others have 
pointed out, configuring this setting in PP turns off all ET rules.  So my question is: are the rules turned on with 
the "security" setting in PP sufficient or should I augment them with rules from the ET set?

Also, a quick question about this suggestion:

2. Since PulledPork now processes modifysid.conf first (before enablesid.conf),
add pcre to modify ET rules to include the desired policy and PulledPork should
pick it up from there. I will need to re-test this one though.

Please forgive my inexperience but I am reading this statement two different ways:

1) Set PP with the security setting and use PCRE to enable ET rules in the modifysid.conf file
or
2) Use PCRE to enable the security sub-set of rules in modifysid.conf while PP is configured to use the ET rule set

Which one is correct, or am I wrong on both counts?

And lastly, if I do use some ET rules in conjunction with the security set of rules I will need to do some serious 
pruning to keep under the aforementioned 7,000 rule suggested limit. Are there any rules that duplicate effort in the 
ET and Security sets?  If so, is there an easy way to identify them and which one should I choose to use?

Thank you all again.

I don't think ET ruleset has these policies.

exactly, thanks for confirming this, YM... it is especially important since the
OP's original question mentioned ET rules...

In the VRT ruleset, these are represented through the "metadata" tag with
options of "policy connectivity-ips", "policy balanced-ips", "policy
security-ips", and the most recent one "ruleset community". PulledPork use
these along with the "-I <policy>" to determine what rules to enable.

yes, this confirms the method with which the policy is determined... it is also
helpful for those who don't know or understand it...

During early tests, running PulledPork against both VRT and ET with a policy
specified, did not enable any ET rule. Two options to overcome this:
1. Add ET sids/categories into enablesid.conf, and PulledPork will enable them
regardless of policy specified, or (better)
2. Since PulledPork now processes modifysid.conf first (before enablesid.conf),
add pcre to modify ET rules to include the desired policy and PulledPork should
pick it up from there. I will need to re-test this one though.

ahh, very nice... i'm glad to see the PP has come such a long way in the short
time it has been available... excellent work by the maintainer! ;)
