SANS ICS410: Hands-On PLC Labs Close the ICS/SCADA Security Skills Gap

Detail

The move from slideware to physical I/O is more than a curriculum refresh. It signals that ICS cybersecurity training is finally aligning with the reality of cyber-to-physical risk, where a compromised PLC is not a data breach but a physical process failure.

Legacy ICS security training has often leaned on theory, diagrams, and simulated environments. ICS410 flips that model. Each student receives a PLC device containing real physical inputs and outputs, which is programmed in class and mapped to an operator interface, or HMI, also built during the session.

This direct manipulation of hardware closes the conceptual gap between network security and plant-floor operations. Students see precisely how a logic change in a controller translates into a physical action, and how an attacker could exploit that same pathway.

Mapping the PLC to a custom HMI reinforces Purdue Model levels 2 and 3, where most control network visibility and risk converge. Students observe data flow from field devices to operator screens, then apply defensive and offensive techniques against real interfaces.

The result is a practitioner who understands both the ladder logic and the attack surface, a profile that employers in energy, manufacturing, and utilities increasingly demand.

The six-day course is built for individuals with an IT or cybersecurity background who need to translate those skills into operational technology environments. Fifteen hands-on labs anchor the learning path.
