ABSTRACT
Modern systems aren't designed to support some ongoing operations after their security has been compromised. Using Sterbenz's ResiliNets (resilient networks) model for describing the tasks of managing a system that might be attacked, the authors discuss five strategies for operating in a degraded security environment: ignorance is bliss (no recovery); response and recovery (no remediation, diagnosis, or refinement); isolate and treat (remediation, followed by recovery); in situ analysis (covert monitoring); and battleshort: hunker down and live with it.
