The convenience of controlling things like lights, thermostats, cameras, and appliances from our phones comes with some risks when it comes to security and privacy. As more Internet of Things (IoT) devices make their way into our homes, it’s important to take steps to keep them and your home network safe from hackers. This article provides tips on securing your connected smart home.

Update Default Passwords
One of the most basic things you can do when setting up a new smart device is change the default password. Manufacturers often set simple default passwords like “123456” or “password” to make initial setup easier. However, that also makes it easier for hackers to guess passwords and access your devices.
- Set a strong unique password for every device. Use a mix of upper and lowercase letters, numbers, and symbols.
- Change passwords regularly every few months.
- Never use personal information like your birthday in a password.
Enable Two-Factor Authentication
Two-factor authentication adds an extra layer of security by requiring two forms of identity verification when logging into an account. Enabling two-factor authentication means that even if a hacker guesses your password, they still cannot access your account or devices without the second factor like a code sent to your phone.
- Check device apps and account settings for two-factor authentication options.
- Set up two-factor authentication through SMS text messages or an authenticator app.
Maintain Firmware and Software Updates
Device manufacturers will periodically release firmware and software updates to fix bugs and security vulnerabilities. Keeping your smart home devices updated is key to preventing issues.
- Enable automatic updates in device settings if available.
- Manually check for new updates every few weeks if automatic updates are not enabled.
Connect Devices to a Separate Network
One risk with IoT devices is that they could provide an entry point for hackers to access your main home network and other connected devices like laptops and phones. Using a separate network just for your smart home devices can limit exposure.
- Set up a separate Wi-Fi network solely for your smart home devices.
- Make sure your main home network with personal devices remains private and secure.
Review Privacy Settings
Many smart home devices connect to a cloud platform or mobile app that collects data and requires an account. Be sure to thoroughly review the privacy policy and limit data collection whenever possible.
- Disable any settings that allow your data to be shared with third parties.
- Only share location data with device apps if absolutely necessary for functionality.
Use Encryption When Available
Encryption protects the data flowing between your smart home devices, routers, hubs, and the cloud. Securing this communication prevents hackers from intercepting any data in transit.
- Check if your Wi-Fi router supports the latest WPA3 encryption standard.
- Enable encryption options in your device settings whenever available.
Monitor Connected Devices
Keeping track of all the devices connected to your home network allows you to identify any unknown or suspicious devices that could indicate a security breach.
- Audit connected devices frequently and compare to your known list of smart home devices.
- Some routers have apps or settings that provide device monitoring and notifications.
