    Getting Started in the Lab Environment

    Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!

  2. Challenge

    Basic OT Network Enumeration

    In this challenge, you'll use standard network scanning tools to identify devices on an operational technology (OT) network, including PLCs and HMIs that control physical manufacturing processes.

  3. Challenge

    Identifying ICS/OT Assets

    In this challenge, you'll identify specific types of industrial control systems by analyzing network protocols and device responses using specialized tools.

  4. Challenge

    Discovering Hidden Assets

    In this challenge, you'll use advanced techniques to discover OT devices that do not respond to standard network scans. You'll uncover hidden assets that are often overlooked during typical security assessments.
