The Rise of IoT: How to Secure Your Connected Devices

From smart thermostats to voice-activated assistants, the Internet of Things (IoT) has become a cornerstone of modern life. Here in the UK, more households and businesses than ever are embracing connected devices to boost convenience, energy efficiency, and even security. But as the number of IoT gadgets increases, so does the potential for cyber threats.

So how can you enjoy the benefits of IoT without compromising your digital safety? In this post, we’ll explore the rise of IoT in the UK and offer practical tips on how to secure your connected devices.

What is IoT – and Why Does It Matter?

IoT refers to the growing network of physical devices connected to the internet – from fridges and doorbells to industrial sensors and wearable tech. These gadgets collect and share data to help automate tasks, improve services, and enhance everyday life.

In the UK alone, the number of IoT devices is projected to exceed 150 million by 2026. Whether you’re using a smart speaker to control your lights or monitoring energy usage with a smart meter, IoT is likely already part of your daily routine.

But with greater connectivity comes greater risk.

The Security Challenge

IoT devices often lack the robust security features found in traditional computers or smartphones. Many come with default passwords, outdated firmware, or limited encryption – making them attractive targets for hackers.

A poorly secured smart device can be exploited to:

• Steal personal data (like login credentials or banking info)

• Eavesdrop on conversations

• Join botnets used for large-scale cyberattacks (like DDoS attacks)

• Compromise your home or business network

In fact, the UK’s National Cyber Security Centre (NCSC) has repeatedly warned about the risks of unsecured IoT devices. That’s why the UK government introduced the Product Security and Telecommunications Infrastructure Act in 2023, mandating better security standards for smart products sold in the UK.

How to Secure Your IoT Devices

While legislation is a step in the right direction, responsibility also lies with users. Here are some simple but effective ways to protect your smart devices:

1. Change Default Passwords

Most IoT devices come with generic default passwords. Always change these during setup. Choose strong, unique passwords for each device, or use a password manager to keep track.

2. Enable Two-Factor Authentication (2FA)

If your device or its companion app supports 2FA, enable it. This adds an extra layer of protection by requiring a code (usually sent to your phone) in addition to your password.

3. Keep Devices Updated

Manufacturers often release firmware updates to patch security vulnerabilities. Make sure auto-updates are enabled, or regularly check for updates yourself.

4. Secure Your Wi-Fi Network

A secure home network is your first line of defence. Change your router’s default settings, use a strong Wi-Fi password, and consider separating your IoT devices on a “guest” network to isolate them from sensitive data.

5. Limit Device Permissions

Some devices ask for more access than they need. Review permissions and disable anything unnecessary – especially access to your location, microphone, or camera.

6. Be Picky with Brands

Stick to reputable brands with a track record of providing ongoing security support. Check for UKCA marking or compliance with UK legislation on product security.

Final Thoughts

The IoT revolution shows no sign of slowing down – and rightly so. Smart devices can make life easier, more efficient, and even safer. But they also open new doors to cyber threats if not properly secured.

By taking a few proactive steps, UK users can enjoy the benefits of connected living while keeping their data and privacy intact.

Stay smart. Stay secure.
