For your business’s network to thrive, you have to really know its details and intricacies. One of the best ways to understand your network is to make a network diagram, which is a visual representation of your network’s devices and how they connect to one another. You can manually create your own network diagram, which can help visualize complex networks. However, it can be difficult and time-consuming to build a coherent, accurate network diagram on your own.

Network diagrams are not only handy to have, but provide a vital look at the network topology for your team, your company, and your peace of mind. Let’s look at what a network diagram is, and why it’s so important. A network diagram is, simply put, a schematic or map of your existing network that illustrates the nodes and their connections. Network diagrams are very useful at mapping out your elements and device interactions, as well as illustrating different network topology types.

The importance of network documentation becomes very clear when you have to sit down and troubleshoot a network from top to bottom. Or when there’s a changing of the guard at your company. New management wants to see what you’re doing with your network. Or new IT staff need to be brought up to speed quickly.

To tackle the risks introduced by open ports, network admins rely on port scanning tools to identify, inspect, analyze, and close open ports in their networks.
