How to secure a smart home automation system?

Smart home automation systems are becoming more and more popular in the UK. They allow you to control lighting, heating, security and entertainment – all from a central hub or smartphone app.

While the convenience is clear, you need to consider the security. There have been reports of hackers getting into smart home devices and smart home automation systems, even using them to spy on homeowners. So securing your smart home is more important than ever.

Here’s how to do it and enjoy the benefits without compromising your privacy.

Keep All Devices Up to Date

One of the easiest ways to secure your smart home automation system is to keep your devices up to date.

Why updates matter

Manufacturers release software and firmware updates to patch security vulnerabilities. If your devices are not up to date they may be at risk.

How to stay current

• Turn on automatic updates where available.
• Manually check for updates every few weeks.
• Set reminders to check device manufacturer websites for latest security patches.

Use Strong, Unique Passwords

Weak or reused passwords are a common entry point for hackers trying to get into your smart home automation system.

Tips for stronger passwords

• Avoid default passwords or easy guesses like “123456” or “admin”.
• Use a mix of upper and lower-case letters, numbers and symbols.
• Create a different password for each device.
• Consider using a password manager to store your passwords securely.

Enable Two-Factor Authentication

Two-factor authentication (2FA) adds an extra layer of protection to your smart home system.

What is 2FA?

2FA requires a second form of verification—like a code sent to your phone—in addition to your password.

Why it’s important

Even if someone guesses your password they still can’t get in without the second verification step.

Secure Your Home Wi-Fi Network

Your Wi-Fi is the backbone of your smart home. If it’s insecure so is everything connected to it.

How to secure your network

• Use a strong, unique password for your Wi-Fi.
• Don’t use personal information like your name or address in your network name.
• Keep your router’s firmware up to date.
• Set up a guest network for visitors, separate from your smart devices.
• Consider using a firewall and a VPN for extra protection.

Be Careful with Device Permissions

Every smart device asks for permissions. But not all of them are necessary.

How to manage permissions* Only grant access to what’s necessary.

• Turn off what’s not needed.
• Review regularly, especially after updates.

Don’t Trust Third-Party Apps

Smart home systems often integrate with third-party apps and services—but not all are trustworthy.

Before you connect:

• Research the app or service provider.
• Check reviews, privacy policies and security credentials.
• Only use apps from reputable companies.

 Be Smart, Be Secure

Smart home automation makes life easier and more efficient. But without security it can make your home vulnerable.

By following the above—keeping devices up to date, using strong passwords, 2FA, securing your network, managing permissions and avoiding untrusted apps—you can protect your system from threats.
