Remote sites with RTUs and field PLCs present specific security problems. These devices run outdated firmware, sit on unreliable networks, and need to keep operating even when connectivity drops. Standard IT security practices do not translate well here.

The Real Challenge

You cannot just patch everything or implement multi-factor authentication when devices authenticate over serial connections. This program addresses practical constraints: limited processing power, no local storage for logs, and operators who need immediate access during emergencies.

We cover firmware integrity verification, secure remote access methods that work over cellular and satellite links, and physical security measures for unmanned locations. You will learn to assess risks based on actual operational impact rather than compliance checklists.

Field-Tested Approaches

The curriculum includes methods used in oil and gas, water treatment, and power distribution—industries where downtime costs thousands per minute and security must coexist with reliability requirements. Expect detailed discussions about legacy equipment and realistic migration strategies.
