As the Internet of Things continues to grow in scale in industrial environments, it’s critical for industry professionals to understand their role in reducing their organization’s risk.

While IoT security is a problem, understanding the scope of the situation is hard to fathom because it can be challenging to find reliable information on the subject. Another hurdle is the sheer variability and scope of the industrial IoT protocol stack, which is becoming increasingly under attack by threat actors who are ramping up their attacks on industrial organizations.

You can help minimize the threat your organization is facing by using a time-tested approach to securing your IoT protocol stack. From providing a foundational perspective on IIoT network protocols and software, we take a look at the security ramifications across the IIoT spectrum and the common protocols extending across an industrial IoT network.

This report covers:

• Why the physical- and link-layer protocols in the IoT protocol stack are often overlooked from a security perspective
• Tactics for protecting the network layer
• Transport layer encryption
• The threat posed by insecured human machine interfaces in industrial environments
