Re: SIEM Use Cases

yes, that is a pretty good scenario that you've outlined.

However, I can't tell how far along you are with your SIEM implementation. 
Also, without knowing which SIEM you're talking about, it's hard to make 
recommendations.

NOT all SIEMs are the same in terms of capability and built in logic 
functions.

I'd suggest you start with the canned features you product has already 
defined.....then pare down once you "tune" it to your environment.

Once you're good at configuring your device, then you can start with your 
own customized alerts.
