Understanding Effects of Norms and Policies on the Robustness, Liveness, and Resilience of Systems - April 2016
Public Audience
Purpose: To highlight project progress. Information is generally at a higher level which is accessible to the interested public. All information contained in the report (regions 1-3) is a Government Deliverable/CDRL.
PI(s): Emily Berglund, Jon Doyle, Munindar Singh

HARD PROBLEM(S) ADDRESSED
- Policy-Governed Secure Collaboration - Norms provide a standard of correctness for collaborative behavior, with respect to which policies of the participants can be evaluated individually or in groups.
- Resilient Architectures - The study of robustness and resilience of systems modeled in terms of norms would provide a basis for understanding resilient social architectures.

ACCOMPLISHMENT HIGHLIGHTS
- We have enhanced the model of the academic research laboratory cybersecurity scenario we have been considering. In particular, we have improved the representation for potential attacks providing greater detail to users. The idea is that doing so will provide a richer basis for investigating how humans react to different sanction policies.
- We enhanced (and are continuing to enhance) our prototype game based on the above-mentioned scenario with which to investigate the effects of different sanctioning mechanisms on the emergence and establishment of various norms pertaining to cybersecurity behaviors.
- We developed an abstract model, called Silk, of a regulated normative system--viewed as a setting for secure collaboration--that supports openness in that participants (modeled as agents) enter the system, interact, and leave but transfer their knowledge to incoming agents. We conducted an agent-based simulation study of Silk. We have shown that social norms promoting conflict resolution emerge under certain assumptions regarding payoffs of the various members.
