The topology of network architecture

When planning your network monitoring, you must understand your network architecture and how you will need to connect it to MDIoT. It is also important to understand how each of your system elements falls into the Purdue model for industrial control system (ICS) OT network segmentation.

MDIoT network sensors continuously detect and monitor network traffic from IoT and OT devices. To get full coverage for your OT/IoT devices, the network sensor needs to be placed in such a way that it can read all the network traffic. Let us delve into this now.

The most common network topologies in OT/IoT networks

The following are some samples of MDIoT sensor placements for different network topologies:

Ring topology: In a ring topology network, nodes or switches create a circular data path. Each switch or node device is connected to two others in a circular format. Collectively, the switches or nodes in a ring topology are called ring networks...
