Re: Disablesid.conf and classtype

[SnortFan <SnortFan () yahoo com>]

Hi Joel,  
    I think I may have found it.  In the pulledpork.conf. I can set the ips_policy.  That will set for me the rule 
policy category mentioned in the article. I could then go back to my enablesid.conf and turn only only the categories 
not included in the ips_policy. 

So for example: if I set the ips policy to security and them add the VoIP catagory in my enablesid.conf, I will get:

CVSS score 8 or greater
Age current back 3 years
Rule categories:
Malware-cnc
Blacklist
SQL injection
Exploit kit
App-detect
VoIP 

I'm I on track?  Also for the VoIP,
Since it's an add on would it activate rules over the age setting older than the policy?

Thanks,
Ed
