As industries rapidly adopt digital transformation, Industrial Internet of Things (IIoT) systems have become central to manufacturing, energy, transportation, healthcare, and critical infrastructure. Smart factories, connected machines, sensors, programmable logic controllers (PLCs), and supervisory control and data acquisition (SCADA) systems now exchange vast amounts of data in real time. While this connectivity improves efficiency, automation, and predictive maintenance, it also introduces significant cybersecurity risks that can impact safety, operations, and even national security.
 
Industrial IoT environments differ fundamentally from traditional IT systems. They combine legacy operational technology (OT) with modern IT and cloud platforms, often operating 24/7 with strict availability and safety requirements. Many industrial devices were never designed with security in mind, making them vulnerable to attacks such as ransomware, sabotage, espionage, data manipulation, and denial-of-service. High-profile incidents involving power grids, manufacturing plants, oil pipelines, and water treatment facilities have demonstrated the real-world consequences of inadequate IIoT security.
 
The Industrial IoT Security course by Uplatz provides a comprehensive, practical understanding of how to secure industrial systems across the entire lifecycle — from device provisioning and network segmentation to monitoring, incident response, and compliance. This course bridges the gap between cybersecurity, industrial engineering, and operational technology, equipping learners with the skills required to protect modern industrial environments.
🔍 What Is Industrial IoT Security?
 
Industrial IoT Security focuses on protecting connected industrial systems, devices, networks, and data from cyber threats while ensuring safety, reliability, and operational continuity.
 
It covers security across:

  • Industrial sensors and actuators

  • PLCs, RTUs, and DCS systems

  • SCADA and HMI platforms

  • Industrial networks (Ethernet/IP, Modbus, PROFINET, OPC UA)

  • Edge gateways and IIoT platforms

  • Cloud-connected industrial applications

Unlike traditional IT security, IIoT security must account for:

  • Legacy systems with limited patching capability

  • Real-time operational constraints

  • Safety-critical environments

  • Long device lifecycles (10–30 years)

  • Physical and cyber threats combined

This course teaches how to design security strategies that respect these constraints while significantly reducing risk.
⚙️ How Industrial IoT Security Works
 
Securing IIoT systems requires a defense-in-depth approach spanning devices, networks, applications, and operations.
 
1. Device Security

  • Secure boot and firmware integrity

  • Device authentication and identity management

  • Hardware security modules (HSMs)

  • Secure configuration and lifecycle management

2. Network Security

  • Network segmentation (IT/OT separation)

  • Industrial firewalls and DMZs

  • Secure industrial protocols

  • Zero Trust principles for OT networks

3. Application & Platform Security

  • Securing SCADA and HMI systems

  • Access control and role-based permissions

  • Secure APIs and data flows

  • Edge and cloud security integration

4. Monitoring & Detection

  • Intrusion detection for OT networks

  • Anomaly detection in industrial traffic

  • SIEM and SOC integration

  • Asset discovery and visibility

5. Incident Response & Recovery

  • OT-specific incident response plans

  • Safe shutdown and fail-safe mechanisms

  • Backup and recovery strategies

  • Post-incident analysis and hardening

6. Governance & Compliance

  • Risk assessments

  • Policy enforcement

  • Regulatory alignment

The course demonstrates how these layers work together to protect industrial environments.
