    Study Notes

    IIoT Architecture

    • Based on the Purdue model
    • Challenges and solutions for IIoT implementation
    • Challenges include interconnectedness of smart devices, larger attack surface, vulnerabilities of SCADA systems, and lack of IT network firewall
    • Solutions include tailored protocols, data segregation, firewalls, multi-factor authentication, and security by design

    IIoT Communication Protocols

    • Controller Area Network (CAN) protocol
    • Message Query Telemetry Transport (MQTT) protocol
    • Constrained Application Protocol (CoAP) protocol
    • Data Distribution Service (DDS) protocol
    • Advanced Message Query Protocol (AMQP) protocol
    • Threats and vulnerabilities include lack of authentication, encryption, and authorization, as well as DoS attacks, MITM attacks, and eavesdropping

    IIoT Control Systems

    • Vital for managing and operating critical infrastructures in industrial environments
    • Examples include smart factories, mining, and supply chains

    Security Threats and Vulnerabilities

    • Types of attacks include:
      • Distributed Denial of Service (DDoS) Attacks
      • Phishing Attacks
      • Side Channel Attacks
      • Man-in-the-middle attacks
      • Ransomware attacks
      • Cyber espionage
      • Web application attacks
      • Supply chain attacks
      • Miscellaneous attacks

    Countermeasures for IIoT
