ICS Security Fundamentals HMI, SCADA & DCS for GICSP Prep

What you'll learn

Understand HMI design principles, alarm management best practices, and how operators interact with industrial processes through human-machine interfaces.
Explain SCADA architecture including master stations, remote terminal units, polling mechanisms, and telemetry communication across distributed assets.
Differentiate DCS from SCADA systems and understand when distributed control is preferred for continuous process operations in industrial environments.
Identify the role of engineering workstations, programming tools, and configuration management in maintaining and securing industrial control systems.
Describe historian platforms like OSIsoft PI, their importance for data archiving, regulatory compliance, and maintaining long-term data integrity.
Recognise Level 2 and Level 3 security challenges including Windows OS vulnerabilities, remote access risks, and OT-specific patch management strategies.

Requirements

Basic understanding of IT concepts such as networking, operating systems, and general cybersecurity principles. No prior OT or industrial experience required.
Familiarity with the Purdue Model or ICS architecture is helpful but not essential — we cover the fundamentals needed to understand Level 2 and Level 3 systems.
Suitable for IT professionals, aspiring OT security specialists, and engineers seeking foundational knowledge of industrial control system technologies.

Description

Colonial Pipeline. Triton malware. Ukraine grid attacks. Industrial control systems are now prime targets — and organisations are scrambling to find professionals who actually understand OT security.
Here's the problem: most IT security professionals have never touched a DCS, configured an HMI, or understood why SCADA polling creates attack surface. That knowledge gap is exactly what's keeping you out of higher-paying OT security roles.
This course closes that gap fast.
In under three hours, you'll build the foundational ICS knowledge that separates OT security specialists from general IT practitioners. You'll learn why HMI design flaws lead to operator errors and safety incidents, how SCADA master stations, RTUs and polling mechanisms work and where attackers target them, what makes DCS architecture different and why it dominates continuous process industries, how historians like OSIsoft PI store critical operational data and why they're high-value targets, where MES systems sit at the IT/OT boundary and why that creates risk, and the specific security challenges of Level 2/3 environments including Windows vulnerabilities, remote access exposure and patching limitations.
This isn't vendor sales material. It's vendor-neutral knowledge aligned with IEC 62443 and the Purdue Model — exactly what GICSP exam objectives cover and what hiring managers expect you to know.
Built by an instructor with 15 years delivering major infrastructure projects and hands-on expertise in IEC 62443 and IEC 61511 functional safety standards.
By the end, you'll confidently discuss control system architecture in interviews, understand the attack surface that keeps OT security teams up at night, and have a solid foundation for GICSP certification or deeper ICS specialisation.
OT security roles pay 20-30% more than equivalent IT positions. The barrier to entry is knowledge. Remove it today.
Enrol now.

Who this course is for

IT professionals transitioning into operational technology roles who need to understand industrial control systems, SCADA, DCS, and OT-specific security challenges.
Cybersecurity analysts and engineers preparing for GICSP, GRID, or other ICS security certifications who want solid foundational knowledge of Level 2/3 systems.
Control systems engineers and automation professionals looking to strengthen their understanding of HMI design, historians, MES, and OT security best practices.
Recent graduates in engineering, IT, or cybersecurity seeking career entry into critical infrastructure sectors such as energy, utilities, or manufacturing.
Project managers and technical consultants working on industrial projects who need to understand control system architecture and communicate with OT specialists.
