Protecting your privacy with smart home devices

In the bustling world of modern technology, smart home devices have quickly evolved from novelty items into everyday essentials. From voice assistants like Alexa and Google Home to intelligent thermostats and security cameras, these devices have undoubtedly made our lives easier and more convenient. But as your home becomes smarter, ensuring the privacy and security of your personal information becomes increasingly vital.

So let's understand the security risks associated with IoT (Internet of Things) devices, and explore practical, easy-to-follow steps you can take to keep your information safe.

What are smart home devices?

Smart home devices are a broad category of network-connected gadgets designed to make everyday life simpler and more comfortable. By linking to your home network and allowing you to control them through a smartphone app or voice commands, these devices can manage tasks like turning lights on and off or even locking and unlocking doors, all from virtually anywhere.

In fact, it's easy to see why these devices have taken off. They offer incredible convenience by automating everyday tasks, saving energy and often money, while enhancing security and peace of mind. Being able to monitor and control your home remotely means you can stay connected no matter where you are and this level of control leads to personalised living experiences that can even improve your well-being.

The adoption of smart home devices

Smart homes are quickly becoming the norm across Europe. In 2023 alone, about 65.5 million European households have already welcomed smart devices into their daily lives and this trend isn't slowing down anytime soon. Experts predict we'll see about 101.2 million smart homes by 2028, growing at around 9% each year.

Revenues from smart home tech are also on the rise, hitting €36.2 billion (approximately US$39.1 billion) in 2023, and they're expected to soar to €65 billion (around US$70.3 billion) by 2028. Plus, with internet access at home reaching 93% across the EU in 2023, it's easier than ever for families to jump onboard.

Understanding the risks of smart home devices

While their convenience is undoubtedly appealing, it's also important to keep in mind the potential security and privacy risks that come with having so many interconnected devices in your home. In fact, smart devices can be vulnerable to cyberattacks. They collect and transmit data, often without the user's full understanding and hackers can exploit weak security features to access not only your device but your entire home network.

But before we get to the solutions, it's essential to understand the security challenges associated with IoT devices.

Weak default passwords

Many smart devices are shipped with default usernames and passwords which, if left unchanged, can easily be exploited by hackers. In fact, IoT devices use simple default credentials like "admin" and "password," making them highly vulnerable to unauthorised access. Back in 2016, in the infamous Mirai botnet attack hackers leveraged thousands of poorly secured IoT devices, from cameras to baby monitors, to launch massive attacks that disrupted major websites like Netflix, AirBnB, Amazon, PayPal and others.

Data breaches and leakage

Some IoT devices store personal data, from your daily schedule to sensitive financial details, to improve functionality. In addition, devices like voice assistants and cameras often collect vast amounts of data, sometimes without explicit user consent, leading to potential privacy intrusions. Instances of Alexa accidentally recording conversations and sending them to unintended recipients raised questions about smart speakers' privacy, which highlighted the importance of regularly reviewing and managing privacy settings on such devices.

Lack of encryption

A number of these devices communicate without robust encryption protocols and without encryption, your data can be intercepted, allowing intruders access to sensitive information about your lifestyle, home security patterns and more.

Outdated software and firmware

IoT manufacturers occasionally neglect software updates, leaving devices vulnerable to newly discovered cyber threats. A 2022 report by Palo Alto Networks revealed that nearly 98% of all IoT traffic was unencrypted and insecure due to outdated firmware. Also, many overlook the importance of securing their Wi-Fi networks, but remember, an unprotected network is like an open invitation for hackers to access your devices.

Tips to safeguard your personal information

Now that we've unpacked some common security risks, let's discuss practical measures to enhance the security of your smart home.

1. Start with Your Wi-Fi network

Securing your home network is the first line of defense. To do so, replace any default admin usernames and passwords with something unique and consider enabling WPA3 encryption, which is the most secure Wi-Fi protocol available. Another tip is to keep your smart devices on a separate network from your primary one by setting up a guest network. If you're having difficulties with coming up with a strong password, read how a password manager can help you with that.

2. Enable multi-factor authentication (MFA)

Multi-factor authentication significantly reduces the risk of unauthorised access by requiring a second verification step, such as a code sent to your smartphone or email. Companies like Amazon and Google now offer MFA on their smart home platforms.

3. Regularly update software and firmware

Regular updates are critical. IoT manufacturers frequently release patches to address security vulnerabilities so you can automate these if possible or set reminders to manually check on a monthly basis.

4. Choose reliable brands and devices

Always opt for smart home devices from trusted manufacturers who prioritise security and privacy. Think of brands such as Apple, Google and Amazon and the likes. Once you've selected a good brand, don't forget to keep your devices up to date. Manufacturers regularly release patches and updates to fix vulnerabilities so make sure you're on top of these.

5. Review device permissions and privacy settings

Regularly review these on your devices and limit access only to the necessary information required for their functionality. For instance, your smart fridge probably doesn't need access to your contact list. Also, most smart devices allow you to customise data-sharing options.

6. Disable features you don't use

If certain smart device features aren't essential for your daily use, disable them. For instance, you can turn off voice recognition when you're not using it, minimising any unnecessary data collection.

7. Invest in a secure IoT hub

An IoT hub can act as a central control point, providing additional security features, plus you'll have unified security settings, encryption and device management, making it easier for you to keep things on top.

Lastly, it goes without saying that you should stay informed about the latest IoT security threats and best practices. Follow tech news, subscribe to security blogs or join online forums dedicated to smart home technology.

The future of smart home security

As more people tune into the importance of IoT security, companies and regulatory bodies worldwide are stepping up their game to ensure smart homes remain safe, hassle-free and enjoyable. We're already seeing exciting innovations like AI-powered threat detection systems that quickly spot unusual activity and blockchain-based platforms designed to securely connect devices in your home. Plus, advanced biometric security, such as fingerprint scans or voice recognition might soon become commonplace, making passwords tougher to crack.

Meanwhile, as these technologies continue to evolve, we can expect smarter firmware updates, robust cloud security and easier-to-use interfaces. All these improvements mean you'll be able to relax knowing your smart home isn't just convenient, but it's genuinely secure too.
