This works well, as the router not only splits the network but allows you to share the single IP address assigned to you by your ISP. In the example above, we set up two local networks isolated from one another by virtue of a split that happens at the router. If you have a wired connection, like that of your kid’s computer in their bedroom, you may not have this option. Unfortunately, guest access is usually restricted to wireless connections. Guest access protects the trusted side from the less-trusted, as no connections can be made between the two and both are protected from the internet. This creates two local networks isolated from each another. Some modern routers offer guest access to the internet. Malicious attempts to get into your computer from out in the wilds of the internet are blocked.
1 In other words, only information your computer asks for comes across the connection. The router protects the trusted side from the untrusted side by preventing incoming connections: only connections that originate from the trusted side can be made across the router. A more simplistic way to think of it is simply this: one side of a router is trusted - the LAN (Local Area Network) into which you plug in your computers - and the other side, the WAN (Wide Area Network), or internet side, is not. Routers protect you from the threats that are “out there” on the internet. One approach is to carve your local network into two: a trusted and an untrusted network. On top of that, we also need to talk about how the “internet of things” and software firewalls affect what we do. This might be easy if your router supports it, or slightly more difficult if not. To protect one bucket from the others, we need to split the network. We’re coming to realize these devices are built with security as an afterthought, if at all. In recent years, more and more devices are getting connected to our internet to create the so-called “internet of things”. These are the computers and devices used by people who are less computer savvy, don’t understand safety, and/or are likely to do things that they shouldn’t, possibly resulting in malware infections.
These are the computers and devices you control and can safely assume are being used by individuals who understand the basics of keeping a computer safe on the internet. We need to group the technology in your home into distinct buckets:
When all else fails - and even when it doesn’t - the software firewall on your computer protects you from all the other devices connected to your network. Failing that, you might enlist help from your ISP to set up a separate network, or you can cobble together a protected scenario using two routers in sequence. Guest access, if supported by your router, is a great way to protect yourself from Wi-Fi-connected computers you don’t completely trust.
