About This Course

Are you ready to move beyond basic IT security and tackle the unique, life-critical challenges of Industrial Control Systems (ICS) and Safety Instrumented Systems (SIS)?

The convergence of IT and Operational Technology (OT) has exposed critical infrastructure to unprecedented cyber threats. The role of the industrial engineer, security professional, and plant manager is fundamentally changing, demanding specialized knowledge in how to strategically secure systems where downtime is measured in safety incidents, not just dollars.

Whether you are aiming to prevent catastrophic failures, strengthen system defenses, or lead your organization's ICS Cybersecurity strategy, this program provides the practical, hands-on knowledge to design and launch advanced OT Security solutions from blueprint to production.

Skills You’ll Get

  • Foundational Concepts & Standards: Master the core principles of Safety Instrumented Systems (SIS) and ICS Cybersecurity, exploring the safety and security lifecycle and essential standards like IEC 62443 for operational integrity.
  • Secure Architecture & Defense: Design resilient Industrial Control Systems (ICS) architectures using Defense-in-Depth (DiD) and LOPA principles, focusing on secure components, protocols, and effective network segmentation (zones and conduits) for OT Security and SCADA protection.
  • Threat Hunting & Hacking Techniques: Understand the SIS attack surface and learn to identify vulnerabilities in systems like PLCs and HMIs. Gain hands-on experience simulating compromises using techniques like the Cyber Kill Chain to inform robust defense strategies.
  • Risk Management & Compliance: Conduct comprehensive Risk Assessment methodologies (including consequence-based risk assessment) to manage residual risk, understand regulatory compliance, and ensure continuous maintenance for Process Safety.
