OT Network Security Monitoring (2026)

OT Network Security Monitoring: Learn Threat Hunting, SIEM, SPAN, TAP, and Industrial Network Monitoring for ICS

What you'll learn
Understand the fundamentals of Operational Technology (OT) and Industrial Control System (ICS) network architecture, including Purdue Model concepts
Learn how to monitor OT network traffic using industry-standard tools such as Armis, claroty and IDS/IPS solutions for detecting suspicious activities
Learn best practices for securing OT environments, improving network visibility, and implementing effective monitoring strategies for industrial cybersecurity.
Understand the differences between IT and OT security monitoring, including safety, availability, and operational considerations in critical infrastructure

Requirements
Basic understanding of computer networking concepts such as IP addressing, TCP/IP, ports, and network communication.
Description
Operational Technology (OT) environments are becoming a major target for cyberattacks, making OT network visibility and security monitoring more important than ever. This course is designed to provide a practical and industry-focused understanding of OT Network Security Monitoring for ICS/SCADA environments.

In this course, you will learn how industrial networks operate, how OT differs from traditional IT environments, and how security teams monitor and detect suspicious activities within critical infrastructure networks. The course covers core concepts such as the Purdue Model, SPAN ports, Network TAPs, RSPAN, ERSPAN, inline monitoring, SIEM log collection, threat intelligence, vulnerability management, and OT threat hunting.

By the end of this course, you will be able to

Understand OT/ICS network architecture and communication

Monitor industrial network traffic effectively

Use SPAN, TAP, and remote monitoring techniques

Integrate OT logs into SIEM platforms

Perform OT threat hunting and anomaly detection

Understand vulnerability management and threat intelligence in OT environments

Improve visibility and security monitoring across industrial networks

This course is suitable for

OT/ICS Security Engineers

SOC Analysts and Threat Hunters

Network Security Professionals

Industrial Automation Engineers

Cybersecurity Students and Beginners interested in OT Security

Whether you are starting your journey in industrial cybersecurity or looking to improve your OT monitoring skills, this course will provide practical knowledge and real-world concepts used in modern OT security operations.

Who this course is for
Basic understanding of computer networking concepts such as IP addressing, TCP/IP, ports, and network communication.
No prior OT/ICS security experience is required — the course starts from the fundamentals and gradually moves to advanced monitoring concepts.
Willingness to learn hands-on OT network monitoring, packet analysis, and threat detection techniques.
Familiarity with general cybersecurity concepts is helpful but not mandatory.
