How to keep your smart tech safe

With help from a new security law and guidelines

Smart tech make our lives easier and more connected. But it’s important that these devices are safe and secure. That’s why, since 29 April 2024, smart device manufacturers must comply with a new UK law.

The law, known as the Product Security and Telecommunications Infrastructure (PSTI) Act is designed to keep your smart tech safer and give you clearer information about its security. Here’s all you need to know.

What changed?

The PSTI Act introduced three key security requirements for smart device manufacturers:

One

No more weak default passwords

Remember when every device came with “admin123” or just “password”? Those days are gone. Now, devices must have unique passwords or require you to create one during setup. This simple change makes it much harder for hackers to break in using common passwords.
Two

A way to report security issues

If a security flaw is found, manufacturers must provide an easy way for users or experts to report it so it can be fixed quickly. This means companies can react faster to potential threats, helping to keep your devices safe.
Three

Clear info on security updates

Manufacturers now have to tell you how long they’ll provide security updates for your device. So, no more guessing when your tech might become vulnerable. Knowing this helps you plan ahead and replace devices before they become liable to potential security risks.

What devices are covered?

If it connects to the internet, your device is most likely covered. These include:

Smart speakers, smart TVs and streaming devices

Icon of video camera

Smart doorbells, baby monitors and security cameras

Icon of gaming console controller

Tablets and gaming consoles

Icon of mobile phone

Smartphones, smartwatches and wearable fitness trackers

Smart gadgets like lightbulbs, plugs and thermostats

Smart domestic appliances like ovens, fridges and washing machines

What does this mean for you?

These new laws offer better protection, fewer security risks, and more transparency about your smart devices. Hackers will have a harder time getting into your smart home, and you’ll know exactly how long your devices will be kept secure with updates. These changes put control back in your hands, helping you make smarter decisions about your tech.

Extra steps to stay secure

Laws help, but there are also lots of things you can do yourself to keep your smart tech safe:

Be cautious with device permissions 

Some devices ask for more access than they need. Limit unnecessary permissions for better security.

Disconnect devices when not in use  

If you’re not using a smart device regularly, consider turning it off or disconnecting it from the internet to reduce risks.

Use a separate Wi-Fi network

Many routers allow you to create a guest network. Keeping smart devices on a separate network can help protect your personal data if one device is compromised.

How to stay informed

Cyber threats change all the time, so staying up to date with security best practices is key. Make sure to regularly check for software updates, review your device settings, and stay informed about potential security risks. Want to learn more?
