This BAA solicitation (HSHQDC-17-R-00059) is a call issued against Department of Homeland Security (DHS), Science & Technology (S&T), Cyber Security Division (CSD), 5-Year Broad Agency Announcement (BAA), HSHQDC-17-R-B0002 Amendment 1. All terms and conditions of the DHS S&T CSD 5-Year BAA HSHQDC-17-R-B0002, Amendment 1, apply to this solicitation unless otherwise noted herein. The overall Application of Network Measurement Science (ANMS) program has several major goals, each corresponding to a separate BAA. The first goal (and the focus of this PARADINE BAA) is to define, identify, produce and report operational instances of disruptive events, accompanied by attribution that captures root cause analysis. The second goal, not included in this BAA, is to predict (with attribution) emerging or unfolding Network/Internet-scale Disruptive Events (NIDEs) based on a thorough understanding of the characteristics of a variety of such events and the current Internet state. The third goal, also not included in this BAA, is to develop a risk analysis tool that supports prediction, what-if scenario exploration, and attribution. Technologies developed under these BAAs should be designed to demonstrate the ability to automatically use very early indications of attack, network instability, broader network behavior, or other domain information to understand the actual properties and details of a Network/ Internet-scale Disruptive Event (NIDE).
