Many industrial control systems (ICS) are reliant upon programmable logic controllers (PLCs) for their operations. As ICS and PLCs are increasingly targeted by cyber-attacks, research facilitating the resiliency of their physical processes is imperative. This paper proposes an approach which leverages PLC containerization, input/output (I/O) multiplexing, and orchestration to respond to cyber incidents and ensure continuity of critical processes. A proofof-concept capability was developed and evaluated on live ICS testbed environments. The experimental results indicate the approach is viable for control applications with soft real-time requirements.
