Architecting Safety Using Cybersecurity Requirements and Assessments

Deploying and maintaining safe processes requires planning and applying knowledge from past tests and experiences. Digitized safety equipment—field devices, controllers, servers—communicating via Ethernet or wireless has surged. Vendors are also rapidly deploying cloud-based services directly connected to critical process assets. Considering cybersecurity early in development enhances safety for people, the environment, and operations.

This presentation covers cybersecurity in safe operations planning. Attendees will explore the ISA 62443 risk management process and high-level risk assessment data gathering. It outlines requirements for architecting and remotely accessing safety enclaves, including potential cloud assets. Cybersecurity vulnerability assessments will be reviewed to aid planning. By the end, attendees will have a foundation for cybersecurity discussions, enhancing process safety in existing and future environments.
