ICS/SCADA Security

Protect critical infrastructure. Secure Operational Technology (OT), SCADA systems, and PLCs against nation-state level threats.

Securing power plants and factories requires different rules than IT. This course bridges the gap between IT security and Operational Technology (OT). You will learn the architecture of SCADA systems, Programmable Logic Controllers (PLCs), and HMIs. Master industrial protocols like Modbus and DNP3, and understand why you cannot just 'scan' these sensitive networks. We cover network segmentation (Purdue Model) and detecting attacks on physical processes.

ICS/SCADA Security FAQs

Critical?

Yes, protects water, power, and manufacturing.

Can I scan it?

Active scanning can crash PLCs; we use passive methods.

Hardware?

We use software simulators for PLCs and HMIs.

Compliance?

Covers standards like NERC CIP and IEC 62443.
