OT/ICS Security Fundamentals
A 5-day intensive course that takes you from ICS architecture basics to hands-on security assessments. Learn to secure industrial control systems with practical, vendor-agnostic techniques used by OT security professionals.
🖥 IT Security Professionals
Moving into OT? This course bridges the IT/OT knowledge gap with practical ICS-specific training you won't find in generic security certs.
🏭 Plant & Facility Managers
Understand the cyber risks to your operational technology and learn to build a security program that protects production without disrupting it.
🔒 OT Security Engineers
Deepen your knowledge with hands-on labs, ISA 62443 compliance frameworks, and modern threat intelligence specific to industrial environments.
📋 Compliance & Risk Teams
Go beyond checkbox compliance. Learn to implement ISA/IEC 62443 in a way that actually reduces risk, not just satisfies auditors.
5 Modules. 40 Hours. Zero Fluff.
ICS Overview & Architecture
Learning Objectives
- Understand SCADA, DCS, and PLC architectures and how they differ from traditional IT systems
- Map industrial environments using the Purdue Enterprise Reference Model
- Identify common ICS protocols (Modbus, DNP3, OPC UA, EtherNet/IP) and their security implications
- Analyze real-world ICS architectures and identify security-critical components
OT Network Architecture & Segmentation
Learning Objectives
- Design secure network architectures that separate IT and OT domains while maintaining operational requirements
- Implement DMZ configurations for safe data exchange between enterprise and industrial networks
- Configure secure remote access for OT environments without exposing critical control systems
- Apply network monitoring strategies tailored to industrial protocols and traffic patterns
OT Threat Landscape & Intelligence
Learning Objectives
- Analyze major ICS cyber incidents (Stuxnet, TRITON/TRISIS, Colonial Pipeline, Oldsmar) and extract defensive lessons
- Identify common attack vectors targeting industrial environments: supply chain, remote access, insider threats
- Apply OT-specific threat intelligence frameworks and risk assessment methodologies (MITRE ATT&CK for ICS)
- Develop threat models for industrial environments that account for safety-critical systems
ISA/IEC 62443 Essentials
Learning Objectives
- Navigate the ISA/IEC 62443 framework structure: general concepts, policies, system requirements, and component requirements
- Define security levels and zones appropriate for your industrial environment
- Build a compliance roadmap that translates 62443 requirements into actionable implementation steps
- Conduct a gap analysis between current security posture and ISA 62443 target security levels
Hands-On Security Assessment
Learning Objectives
- Perform passive and active OT network reconnaissance without disrupting industrial processes
- Execute vulnerability assessments on ICS components using OT-safe scanning techniques
- Develop an incident response plan specific to OT environments with safety-first protocols
- Create a security program development roadmap with prioritized remediation actions
