Publication number: 20250141730Abstract: 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.Type: ApplicationFiled: January 2, 2025Publication date: May 1, 2025Inventors: Swapna Anandan, Elango Ganesan, Flemming S Andreasen

Publication number: 20240364687Abstract: This disclosure describes techniques for validating a network device based on an operational context of the network device. The techniques may include receiving, via an intercepting node, a DNS query from a querying device. The techniques may include extracting the metadata from the DNS query. Based at least in part on verifying a signature of the metadata, the techniques may include extracting a location code from the metadata. Based at least in part on comparing the location code to an expected location of the intercepting node, the techniques may include sending a response to the querying device indicating a contextual validation of the querying device.Type: ApplicationFiled: April 25, 2023Publication date: October 31, 2024Inventors: Robert Edgar Barton, David John Zacks, Thomas Szigeti, Flemming S.
