What you'll learn

  • Apply the OSI 7-layer model to secure industrial control systems and SCADA networks from physical layer through application
  • Implement network segmentation strategies aligned with IEC 62443 zones and conduits for OT environment protection
  • Configure firewalls, NAT, and IPsec to secure OT/IT network boundaries and encrypted industrial communications
  • Detect and prevent common network attacks including ARP spoofing, SYN floods, and DNS cache poisoning in ICS environments
  • Deploy network monitoring, IDS, SIEM, and logging tools specifically configured for industrial control system security
  • Apply cryptographic techniques including symmetric/asymmetric encryption, hashing, and key management to protect OT systems
  • Implement Quality of Service (QoS) traffic prioritization to protect critical industrial communications
  • Secure industrial protocols, DNS, NTP, and precision time distribution (PTP/IEEE 1588) in control system networks
