From smart thermostats and doorbells to voice assistants and fitness trackers, smart devices are everywhere. While these gadgets bring convenience and connectivity into our homes and lives, they also create new vulnerabilities. Each connected device is a potential entry point for hackers. Fortunately, with a few proactive steps, you can significantly improve your security and protect your personal information. Here’s your complete guide to securing your smart devices from cyberattacks.
Why Smart Devices Are Attractive Targets
- Weaker Security: Many smart devices have less sophisticated security than computers or smartphones.
- Default Settings: Devices often ship with default usernames and passwords, making them easy targets if not changed.
- Always On, Always Connected: Their constant connection to the internet makes them accessible to attackers 24/7.
- Data Collection: Smart devices often collect and store personal data that hackers can exploit.
Bottom line:
Without proper safeguards, your smart home could turn into a hacker’s playground.
Essential Steps to Secure Your Smart Devices
1. Change Default Usernames and Passwords Immediately
Why:
Default login credentials are often published online and easily exploitable by hackers.
How to do it:
- Create strong, unique passwords for each device.
- Use a mix of upper- and lowercase letters, numbers, and symbols.
- Avoid obvious choices like “123456” or your pet’s name.
Pro tip:
Consider using a reputable password manager to generate and store complex passwords.
2. Keep Your Devices Updated
Why:
Manufacturers regularly release updates to patch security vulnerabilities.
How to do it:
- Enable automatic updates when possible.
- Regularly check for firmware updates manually if auto-update isn’t available.
- Replace outdated devices that no longer receive updates.
Pro tip:
Schedule a monthly reminder to check your device settings for updates.
3. Secure Your Wi-Fi Network
Why:
Your Wi-Fi network is the backbone that connects all your smart devices. If it’s insecure, everything attached to it is vulnerable.
How to secure it:
- Set a strong, unique password for your Wi-Fi network.
- Use WPA3 encryption (or WPA2 if WPA3 isn’t available).
- Hide your network’s SSID (network name) if you don’t need it to be visible to the public.
- Create a separate network for smart devices (most modern routers allow this).
Pro tip:
Many routers now offer a “guest network” option—perfect for isolating smart devices from your main network.
4. Disable Unnecessary Features
Why:
Features like remote access, UPnP (Universal Plug and Play), or voice controls can create additional vulnerabilities.
How to do it:
- Review device settings and disable features you don’t need.
- Turn off cameras or microphones when not in use, if possible.
- Deactivate remote access unless you truly need it.
5. Use Two-Factor Authentication (2FA)
Why:
2FA adds an extra layer of security by requiring a second form of verification beyond just a password.
How to enable it:
- Check device settings or linked apps for 2FA options.
- Use an authenticator app rather than SMS for better security.
Pro tip:
Whenever a device or service offers 2FA, take advantage of it.
6. Monitor Device Permissions and Data Sharing
Why:
Many smart devices collect more data than necessary, and unnecessary permissions could open up vulnerabilities.
How to do it:
- Review privacy settings.
- Limit the amount of personal information you provide.
- Opt out of data sharing wherever possible.
Pro tip:
Be cautious about linking your devices to third-party apps unless absolutely necessary.
7. Invest in a Secure Router and Firewall
Why:
An older or basic router might not offer the security features needed to protect modern smart homes.
What to look for:
- Built-in firewalls
- Automatic firmware updates
- Support for guest networks
- Intrusion detection systems
Pro tip:
Some newer routers are designed specifically for smart homes and prioritize security features.
8. Turn Off Devices When Not in Use
Why:
Fewer active connections mean fewer opportunities for cyberattacks.
How to do it:
- Turn off smart plugs, lights, and cameras when you’re away or don’t need them.
- Unplug devices during vacations or extended absences.
9. Regularly Audit Your Devices
Why:
The more devices you connect, the more entry points you create.
How to audit:
- Keep a list of all connected devices.
- Periodically review what’s connected to your Wi-Fi network.
- Remove and factory-reset any devices you no longer use.
Pro tip:
Your router’s admin page or app often shows all connected devices—review it regularly.
10. Stay Educated and Aware
Why:
Hackers constantly develop new tactics. Staying informed helps you stay protected.
How to do it:
- Follow cybersecurity news from reputable sources.
- Subscribe to updates from device manufacturers about potential vulnerabilities.
- Keep learning about new smart device best practices.
Bonus: Products That Help Secure Your Smart Home
- Bitdefender Box: A cybersecurity hub for your connected devices.
- Eero Secure or Nest WiFi: Routers with built-in security services.
- Firewall hardware like Firewalla: Monitors traffic for suspicious activity.
- VPN services: Encrypts your internet traffic for additional privacy.
As smart devices become a bigger part of our daily lives, securing them isn’t optional—it’s essential. By taking proactive steps like changing default settings, updating software, securing your Wi-Fi, and being mindful of data sharing, you can enjoy the convenience of a connected life without exposing yourself to unnecessary risks. Cybersecurity starts at home, and even small actions can make a big difference. Stay smart, stay safe, and keep your digital life under your control.
