MGDefender: Scan-Cycle-Aware PLC Protection Through Embedded Virtualization and Lightweight I/O Anomaly Detection
- Published
- Record updated
Summary
MGDefender is a host-side protection framework for PLCs that separates control and anomaly inference into real-time (RTVM) and general-purpose (GPVM) virtual machines, passing fixed-size I/O snapshots through a restricted shared-memory ring buffer. Its MGD-DSPC detector combines multivariate Gaussian denoising with lightweight dynamic statistical process control to flag process-state deviations. On Raspberry Pi 4B/OpenPLC, the author-archived measurements show microsecond-level cross-domain transfer and millisecond-level online inference, with limited measured CPU and memory overhead.
