Experimental Evaluation and Analysis of Additional Mitigations

Evaluate experimentally and analyze the implications of demand-side restrictions, geographic ingress limits, detection and containment mechanisms, multi-satellite coordination, dynamic beamforming, and robust scheduling policies for reducing the effectiveness or increasing the cost of JANUS demand-manipulation attacks.

Background

The paper proposes several mitigation directions beyond the scheduler-side mechanisms evaluated experimentally. These include limiting scheduler-visible or admitted demand, restricting ingress by geographic source area, detecting coordinated demand manipulation, coordinating beam allocation across overlapping satellites, dynamically reconfiguring beam coverage, and training robust scheduling policies on adversarially shaped demand.

The authors explicitly defer experimental evaluation and further analysis of these concrete defense mechanisms, leaving their effectiveness, tradeoffs, and operational implications unresolved.
