OT/ICS Security curriculum: 5 modules over 5 days
Module 1 : OT/ICS Security 2026 Fundamentals: Industrial Architectures and Protocols (Modbus, DNP3, Wireshark Tools)
Discover the specifics of OT/ICS environments through detailed analyses of PLC, RTU, and SCADA architectures, using Wireshark to dissect Modbus and DNP3 traffic. Participate in practical network mapping exercises, identify common vulnerabilities such as unencrypted communications, and produce an initial segmentation diagram. This immersive approach strengthens your professional skills for immediate enterprise securing.
Module 2 : Threats and Vulnerabilities in OT/ICS Security 2026: Risk Analysis (Stuxnet, TRITON Cases, Virtual Labs)
Dive into ICS-specific cyber threats like Stuxnet or TRITON through simulations in secure virtual labs. Analyze attack vectors via USB, social engineering, or legacy protocol exploitation, test OT-adapted Nmap scans, and assess impacts on industrial production. Each participant develops a prioritized risk report, applying recognized methods for proactive detection in a professional certifying context.
Module 3 : Hardening and Segmentation in OT/ICS Security 2026: Firewalls, VLANs, and Purdue Model (ICS-CERT Tools)
Learn to implement the Purdue Model to segment IT/OT zones, configure next-gen firewalls like Palo Alto to filter ICS protocols, and deploy secure VLANs on industrial switches. Through practical workshops on PLC emulators, test blocking rules against lateral movement attacks, generate deployable configurations, and optimize the resilience of critical systems for robust enterprise protection.
Module 4 : Monitoring and Detection in OT/ICS Security 2026: Dedicated SIEM, IDS/IPS (Splunk, Nozomi)
Install and configure SIEM tools like Splunk or Nozomi to monitor OT traffic in real-time, detect anomalies via custom rules on DNP3 and EtherNet/IP. Perform event correlation exercises, simulate intrusions to validate alerts, and produce operational dashboards. This practical session elevates your skills in proactive monitoring, essential for professional industrial security teams.
Module 5 : Incident Response and Compliance in OT/ICS Security 2026: Playbooks, Exercises (NIST 800-82, Certification)
