Most people assume their home network is reasonably secure because they have a WiFi password. That assumption is mostly wrong — and it matters more now than it ever has, because the average Southern Highlands home now has 15–25 devices connected to the network at any given time. Each one is a potential entry point.
This isn't a reason to panic. It is a reason to do a few things properly.
Change the default router login credentials
Every router ships with default admin credentials — usually something like admin/admin or printed on a sticker. These are publicly known. If your router is still using them, anyone on your network can access the admin interface. Change the admin password to something long and unique as soon as you set up a new router.
Separate your IoT devices from your important devices
This is the single most effective security measure most people have never done. Your smart TV, robot vacuum, baby monitor, smart switches, and security cameras don't need to be on the same network as your laptop and phone. In fact, they shouldn't be.
IoT devices often have poor security — infrequent updates, weak encryption, and sometimes known vulnerabilities. If they're on the same network as your computer, a compromised device can potentially access everything else. On a properly configured network, IoT devices are on a separate VLAN — they can access the internet, but they can't see your other devices.
💡 A properly segmented network has at minimum: a main network for your phones and computers, a separate IoT network for smart devices, and a guest network for visitors. These are standard on every network we build.
Set up a proper guest network
If visitors or Airbnb guests use your WiFi, they should be on a guest network that's isolated from your main network. Guest network isolation is a basic feature on any decent router — but it's only useful if it's properly configured. A misconfigured guest network can still allow access to your main devices.
Keep firmware up to date
Router firmware updates fix security vulnerabilities. Consumer routers often go years without firmware updates because the owners don't know to check. Enterprise-grade routers like UniFi have automatic update options and active security patch cycles. This is one of the less glamorous but genuinely important maintenance tasks.
What about cameras and smart locks?
These devices deserve particular attention because they're directly connected to your physical security. Cheap cameras with generic firmware are a known security risk — there have been numerous cases of poorly secured cameras being accessed remotely. We only install UniFi Protect cameras, which store footage locally on your own hardware with no cloud dependency, and which receive regular security updates.
Smart locks should be on an access-controlled network segment, with audit logs of who entered and when. This is standard in every UniFi Access setup we install.
Remote monitoring
A well-maintained network should have someone watching it. We remotely monitor every network we install via UISP — we can see device connectivity, performance, and unusual activity. If something looks wrong, we know about it, often before the client notices anything.
The realistic picture: A properly secured home network doesn't require being a security expert. It requires the right hardware, proper initial configuration, and someone keeping an eye on it. All three of these are things we handle.
