Set up a virtual LAN (VLAN), they said. It would be fun, they said. Actually, configuring VLANs is incredibly fun and worthwhile as it can segment your network and secure various devices. Think about all those random guest phones that gain access to your wireless network. There’s no telling what those visiting your home may do on their devices. All it takes is one innocent visit to a dodgy streaming website with malware ready to ship out to the next unsuspecting victim. Once that code is on your network, it can spread to other devices, which is what VLANs can help protect against.
