Thresholding by source AND destination

["Turnbough, Bradley E." <bturnbough () belcan com>]

Hello,

A kind person sent me information last week regarding a solution to allow me to disregard events when from a certain 
source to a certain destination.  Can someone please give me a better idea how to do this?

For example:

I have a source DNS server IP address of 1.2.3.4 and a destintation DNS server of 5.6.7.8

This alert is being generated:

INDICATOR-COMPROMISE Suspicious .cn dns query

BUT.... This is for a domain that I know is a legit domain.

dns.abc.cn


So, I want to exclude (threshold / not alert) suspicious CN domain resolution requests when coming from 1.2.3.4 and 
going to 5.6.7.8 for a DNS request of dns.abc.cn

Hopefully I explained myself well enough.

Thanks,

Brad
