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
