Instructor - OT Security

Key Responsibilities

• Plan, design and deliver training sessions on OT/ICS Security
• Teach OT fundamentals, including industrial processes, PLCs, RTUs, HMIs, DCS and the Purdue Model
• Explain OT environments and industrial business processes across manufacturing, energy, utilities, transportation and other critical infrastructure sectors
• Train learners on ICS/SCADA security, including common threats, vulnerabilities and attack scenarios specific to industrial environments
• Explain and apply the IEC 62443 series, including zones and conduits, security levels and secure lifecycle requirements
• Teach NIST OT security frameworks and guidance (NIST SP 800-82, NIST CSF) and how to map them to real-world environments
• Train learners on OT network security: segmentation, industrial protocols (Modbus, DNP3, OPC UA, etc.), monitoring and secure remote access
• Highlight the differences between IT and OT security, including safety, availability and legacy system constraints
• Train learners on OT risk assessment, safety-critical operations, the impact of cyber incidents on physical processes, operational continuity and risk mitigation
• Develop and deliver hands-on labs using OT/ICS simulators, virtual environments, industrial network traffic and controlled security scenarios, along with case studies and assessments
• Track batch attendance, performance and feedback, and share regular reports
• Resolve learner doubts and provide mentoring and guidance
• Coordinate with internal teams to complete schedules and deliverables on time

Required Skills

• OT/ICS Security Fundamentals and OT Fundamentals
• ICS/SCADA architecture, components and security risks
• IEC 62443 standards and their application
• NIST OT security frameworks (NIST SP 800-82, NIST CSF)
• OT Network Security: segmentation, firewalls, industrial protocols and monitoring
• Understanding of IT vs OT security differences and risk management in industrial environments
• Strong communication, presentation and facilitation skills
• Practical familiarity with OT security tools, industrial simulators, lab environments and industrial network traffic analysis
• Understanding of industrial safety principles, safety-critical systems and operational continuity

Experience / Selection Criteria

• Prior experience delivering technical training, workshops or structured knowledge-transfer sessions is preferred
• Ability to conduct a technical demonstration covering OT/ICS architecture, IEC 62443 zones and conduits, OT network security and an industrial incident scenario.
