Security and privacy

As you connect more devices to your home network, security and privacy become increasingly important. A smart home generates a significant amount of data about your daily routines, and it is essential to ensure that this information is protected from unauthorised access.

Key security risks

  • Unauthorised access: If your devices or accounts are not properly secured, hackers could potentially control your heating, lighting, or even access cameras.
  • Data leaks: Smart home manufacturers collect data about your usage. If their servers are breached, your personal information could be exposed.
  • Vulnerable devices: Some low-cost smart devices have poor security features and may not receive regular firmware updates, making them easy targets for attacks.

How to protect your smart home

1. Secure your Wi-Fi router

Your router is the gateway to your smart home.

  • Change the default password: Never use the password that came with the router.
  • Use WPA3 encryption: If your router supports it, use the latest security standard.
  • Create a guest network: Many experts recommend putting your smart devices on a separate “guest” Wi-Fi network so they cannot access your main computers and phones.

2. Use strong, unique passwords

Use a different password for every smart home account (Nest, Hive, Philips Hue, etc.). A password manager can help you keep track of these.

3. Enable Two-Factor Authentication (2FA)

Wherever possible, enable 2FA on your smart home accounts. This adds an extra layer of security by requiring a code from your phone in addition to your password.

4. Keep firmware updated

Manufacturers regularly release updates to fix security vulnerabilities. Most smart devices can be set to update automatically; ensure this feature is enabled.

5. Research manufacturers

Before buying a new smart device, research the manufacturer’s reputation for security and how long they promise to support the device with updates.

Privacy Tip: Review the privacy settings for your voice assistants and smart cameras. You can often choose to delete your voice recording history or limit the data that is shared with the manufacturer.

Security Checklist

  1. Audit your devices: Do you know every device that is connected to your network?
  2. Update your router: Is your router running the latest firmware?
  3. Check for 2FA: Have you enabled two-factor authentication on your primary smart home accounts?
  4. Remove unused devices: If you no longer use a smart device, disconnect it and remove it from your account.
