Smart Home Security 101: Essential Steps to Protect Your Connected Devices

Your smart home setup offers a taste of the future. However, when camera glitches expose your space, smart speakers are compromised, robot vacuums act out, or security systems are breached via a smart plug, it’s understandable to feel cautious about connecting everything online.

There’s no need to avoid smart home devices altogether. Instead, it’s essential to understand potential risks and use security features effectively. Whether your setup includes a fully automated kitchen or just one voice assistant, here’s a guide to safeguarding your home network.

1. Prioritize Devices That Suit Your Needs

Before purchasing a smart speaker, thermostat, or camera, consider how much convenience you’re comfortable trading for privacy. For instance, security cameras add protection but may store footage on remote servers. Similarly, voice assistants are always listening for commands, which may or may not sit well with you. Decide where you draw the line between convenience and privacy.

2. Secure Your Wi-Fi Network

Most routers come with model-specific SSIDs and default passwords, which hackers can easily find online. Secure your Wi-Fi with a strong, unique password and, if possible, update the SSID. Many routers allow security management through apps, where you can also upgrade to the highest security protocol available, like WPA3.

3. Keep Firmware Updated

Firmware is the foundational software running your router and smart devices. Companies regularly release updates to improve security and add features. Some devices auto-update, but others may require manual installation. If auto-updates aren’t feasible, set reminders to periodically check for them to protect against known vulnerabilities.

4. Upgrade Outdated Routers

Old routers may lack the latest security protocols, making them vulnerable. If you haven’t updated your router in years, consider a Wi-Fi 6 model for enhanced security and performance.

5. Use Unique Passwords for Device Accounts

While reusing passwords is convenient, it’s risky. If a password is compromised, it can expose other accounts that share it. Use distinct, strong passwords for each account, or try a password manager to keep track.

6. Enable Multi-Factor Authentication (MFA)

For accounts that support it, MFA adds another layer of security. Even if a password is compromised, hackers will need additional authentication to gain access. Many smart home services support MFA via authenticator apps like Google Authenticator.

7. Create a Separate Network for Smart Devices

The FBI suggests placing IoT devices, like a smart fridge, on a different network than personal devices. Use a separate band on your router or the guest network option to separate these devices from sensitive data. This adds a barrier, so malware on IoT devices has less chance of affecting primary devices.

8. Monitor Network Activity

Consider using network monitoring tools, such as Wireless Network Watcher, to keep tabs on connected devices. Comprehensive security software can also provide extra protection, alerting you to unusual network activity and helping block potential threats.

By following these steps, you can enjoy the benefits of smart home technology while keeping your network secure.
