How do I secure my smart home devices?
Secure your smart home by changing every default password, enabling WPA3 encryption on your router, updating device firmware regularly, and isolating smart gadgets on a separate guest Wi-Fi network. These four moves block the most common attack paths criminals use to hijack cameras, TVs, and other connected devices in your house.
- Change every default password on your router, cameras, and smart hubs to unique, strong passphrases today.
- Switch your router to WPA3 encryption, or WPA2 with AES if WPA3 is unavailable on older hardware.
- Create a separate guest Wi-Fi network and connect all smart TVs, cameras, and plugs to it.
- Enable automatic firmware updates on every device, and manually check models that lack auto-update support.
- Disable remote admin access, UPnP, and port forwarding on your router unless you actively use them.
- Turn on multi-factor authentication for every cloud account tied to cameras, doorbells, and smart hubs.
- Retire any device that no longer receives security updates, or isolate it on the guest network permanently.
Why your smart home is a target
The numbers are hard to ignore. More than 820,000 IoT attacks happen every single day, according to threat data compiled by StationX in October 2026. The average connected household faces nearly 30 of those attacks every 24 hours, spread across roughly 22 devices, based on telemetry from NETGEAR and Bitdefender.
Here is the part that should worry you most: 98% of all IoT device traffic crosses the network unencrypted, per Palo Alto Networks. That means the chatter between your gadgets and the internet is readable by anyone positioned to listen. Your smart home is not just convenient. It is exposed.
Secure your smart TV
Your TV is a computer that happens to show movies, and attackers treat it that way. In October 2026, researchers at SSD Secure Disclosure revealed pre-authentication vulnerabilities in LG’s webOS that could give an attacker on the same local network root access to certain smart TVs, no PIN or interaction required. The chain was tested on the 32LQ636BPSA and 27TQ600SW models running webOS 7.5.7-25 on firmware 04.54.40. LG has issued a fix.
But hacking is not the only way your TV watches you. Most smart TVs ship with automatic content recognition (ACR) enabled, a feature that fingerprints everything on your screen, from streaming shows to game consoles plugged into HDMI, and sends viewing profiles back to the manufacturer and its advertising partners. Consumer Reports and the FTC have both flagged this as a privacy risk most owners never opted into knowingly.
Check for a firmware update on your TV right now. Then dig into the settings and turn off anything you do not use: voice assistants you never talk to, advertising identifiers, and automatic content recognition. A TV that cannot phone home with your viewing habits is a TV with less to steal.
Secure your security cameras
Cameras are the device hackers want most, because the payoff is intimate. Change the default admin password on every camera the day you install it. If the camera has its own cloud account, protect that account with multi-factor authentication and a unique password.
Review who has shared access. Old roommates, ex-partners, a housesitter from two years ago. Remove anyone who no longer needs it. And check the camera’s retention settings so footage is not sitting in the cloud longer than necessary.
Secure your robot vacuum and small gadgets
Small gadgets get overlooked, which is exactly why they are dangerous. In February 2026, a security flaw was found that could have let attackers remotely activate the cameras and microphones on around 7,000 robot vacuum cleaners of the same model, as reported by AzerNews. These machines map your home’s layout as they clean. In the wrong hands, that map plus a live microphone is a burglary toolkit.
The fix is boring but effective: keep the vacuum’s app updated, use a strong unique password on the vendor account, and disable remote access features you never use. Apply the same thinking to smart plugs, bulbs, and speakers. If a gadget has not received a firmware update in years, the vendor has moved on. You should too, or at least quarantine it on the guest network.
Lock down your router, the biggest target of all
Your router is the front door, and attackers know it. Routers account for 75% of all IoT attacks, according to Dexpose threat data. Everything else on this list matters less if the router itself is compromised.
The FTC’s guidance is straightforward: secure the router first, change its default administrative credentials, and keep it updated. CISA calls WPA3 the strongest encryption currently available for home Wi-Fi, with WPA2 and AES as the fallback. Never run an open network, WEP, or the original WPA. Both the NSA and CISA recommend putting smart home devices on a separate guest or IoT network, so a compromised bulb cannot reach your laptop or spread further.
What to do if a smart device gets hacked
Signs include unfamiliar devices on your network, settings you did not change, or a gadget behaving strangely. Do not panic, but act quickly.
Disconnect the suspicious device from your network immediately. Change your Wi-Fi password and the router’s admin password. Update the firmware on every connected device, and check each vendor account for unfamiliar logins or shared users. If a camera was involved, assume any footage it captured may have been seen and review what it could observe.
Honestly, the uncomfortable truth is that most smart home hacks succeed because the owner never spent ten minutes on setup security. The manufacturers ship convenience first and hardening second. That ten minutes is the entire difference between a target and a dead end.
