Re: metadata questions

["Morris, Shane (US SSA)" <shane.morris () baesystems com>]

I have SF 5.x and OpenSrc Snort so that's good to know about OS Snort; I thought it was the same requirement in the 
newest version of Snort.

Example:
content: "hello"; metadata: service http;
If we want this to fire in both http and non http streams (non-defined protocol), how do we do this?

1.       According to the snort manual the metadata key values are engine, soid and service but Ive seen rules written 
with other options like "metadata: author snortguru". Is there a list of available keys or are all keys other than 
engine, soid and service treated as comments.

It's a free flowing text field.  The only field that Open Source Snort uses is "service", and only if you have Adaptive 
profiling turned on with a host attribute table.


 2.       If I am writing a rule that I want to fire on HTTP and non-HTTP traffic how could I do this since you have to 
use metadata and specify a service in the newest version of Snort?

Can you give me an example?  (you only have to specify a service in the >=5.x Sourcefire product, this does not effect 
Open Source Snort)
