Abstract: Embodiments relate to a method for enhancing and prioritizing operation technology (OT) control systems in a safety instrumented system (SIS) environment by incorporating safety levels. The method includes receiving network packets associated with OT systems by network interface. From network packets, OT systems associated with safety integrity level (SIL) values are identified. In response to identifying OT control systems associated with SIL values, determining priority levels from SIL values of OT systems. The method includes identifying, among OT control systems, network packets associated with a critical OT system associated with a SIL value having a higher priority level. The critical OT system may be prioritized that comprises encoding the network packets of the critical OT system, with corresponding SIL value. The prioritized critical OT system may be prioritized based on SIL value and classified into a network group associated with a network tag to deliver traffic with higher priority.
