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
