Why Network Segmentation is Key

Network segmentation is the process of dividing your network into smaller subnetworks. This helps isolate IoT devices from other devices, reducing the risk of a breach spreading throughout your entire network. By segmenting your network, you can also apply different security policies to different groups of devices, ensuring that each group gets the appropriate level of protection.

Think of network segmentation like building walls between different rooms in your house. If one room gets compromised, the rest of the house remains safe. It's a simple yet effective way to enhance your network's security.

Common Issues and How to Fix Them

Even the best-laid plans can go awry sometimes. Here are some common issues you might encounter when setting up a remote SSH IoT firewall free system and how to fix them:
