Abstract	Smart infrastructure combines physical assets, sensing devices, communication networks, computational platforms and automated control. Electricity networks, water systems, transportation services, intelligent buildings and industrial facilities increasingly depend on cyber-physical connectivity to improve efficiency, visibility and responsiveness. This connectivity also creates new pathways through which cyberattacks, sensor failures, communication disruptions and physical disturbances can propagate across interconnected services. Conventional cybersecurity controls can reduce the likelihood of intrusion, but they cannot guarantee that every attack will be prevented. Infrastructure resilience must therefore include the capacity to anticipate adverse conditions, withstand partial compromise, maintain essential functions, recover service and adapt from operational experience. This study develops a conceptual architecture for cyber-physical resilience integrating security controls, heterogeneous sensing, physics-informed anomaly detection, resilient state estimation and bounded autonomous control. The framework separates preventive security from operational resilience while connecting both through a continuous decision cycle. A structured review of research concerning cyber-physical systems, false-data injection, resilient control, infrastructure interdependency and cyber-resiliency engineering supports the proposed design. An author-generated simulation compares a conventional recovery architecture with an integrated resilient-control architecture across 100 hypothetical disruption scenarios per condition. Median recovery time decreases from 84.8 hours to 35.5 hours, while mean recovery time decreases from 87.1 hours to 37.2 hours. The 90th-percentile recovery time falls from 118.0 hours to 56.4 hours. Additional simulated outcomes include improved essential-service continuity, faster anomaly isolation and fewer unsafe autonomous actions. These numerical values are illustrative and do not represent measurements from an operational infrastructure provider. The findings indicate that cyber-physical resilience cannot be achieved through network security, sensing or automation independently. It requires trustworthy integration of all three capabilities. Autonomous control should operate within verified safety envelopes, degrade gracefully when information becomes unreliable and provide clear pathways for human intervention. Effective implementation also requires secure system architecture, diverse sensors, tested fallback modes, coordinated recovery plans and governance that identifies responsibility for automated decisions.
