Access Denied and Sector Down: Introducing Resilience Games for Critical Infrastructure Preparedness

By Christopher Schwartz, Jessica D. Bayliss, David I. Schwartz, A. David Abitbol, and Brian Tomaszewski

Critical infrastructure (CI) organizations increasingly face disruptions that cascade across interdependent systems. Preparing for this fact requires thorough training, yet many existing training methods, especially tabletop exercises, are too resource-intensive, classified, or narrowly scoped to prepare diverse civilian and military stakeholders effectively. To address this gap, we introduce resilience games, a form of serious gaming with wargaming elements. First, we present the JV4.0 technical framework, the latest iteration of the U.S. Army Cyber Institute’s Jack Voltaic series, an open-source, modular architecture for creating, running, and adapting such games. Second, we demonstrate Access Denied and Sector Down as two implementations of the framework. Access Denied is an entry-level, non-technical card game focused on incident recognition and communication. Sector Down is a cross-sector game that trains CI decision-makers to sustain essential functions under cascading attrition. We describe gameplay mechanics, alignment with practitioner taxonomies (e.g., CISA lifelines, MITRE ATT&CK/ICS, D3FEND), and insights from formative playtesting across military, academic and public venues. We conclude by outlining next steps for empirical evaluation and policy integration. The aim is to provide a scalable, accessible tool to help Department of War installations and civilian communities prepare for disruptions ranging from cyberattacks to extreme weather events.
