For our first step, our InfoSec team deployed two pair of Sourcefire IPS inline (to cover both Internet and intranet traffic) to the highly secure data center John mentioned in this post. We'll enable blocking of select, high-fidelity signatures next Thursday. Building on the stability and efficacy we're already seeing, we believe the added features of automated vulnerability and user correlation will further speed our incident detection. No hard metrics for you yet, but so far things are looking very good.
