Re: [SUSPECTED SPAM] Returned Errors for CISA Snort Rules

That looks like an abuse of classtype, but to add new classtypes for Snort 2 you need to update 
etc/classification.config.

Subject: [SUSPECTED SPAM] [Snort-sigs] Returned Errors for CISA Snort Rules

Hello,
I've been trying to implement Snort rules provided by the CISA but I'm
receiving errors when the classtype field contains the value "http-uri"
or "http-header"  (examples provided below). These are not default Snort
classtypes. Can someone provide some insight on how to either define
these classtypes OR provide a good alternative classtype?
Thanks in advance for any insight you can provide!

Best,
Chris
