A home is often considered a safe place. However, with the rise of smart home devices, the Internet of Things (IoT) has introduced new risks. From connected doorbells and smart sensors in modern kitchen appliances to voice assistants and security cameras, these devices have revolutionised the way we work and live, but if left unsecured, they can also provide new entry points for cybercriminals.
IoT captures vast amounts of data, including our location, how we shop, the content we see, and our network environments. All the data is stored, parsed, and transmitted over an ever-expanding global network, which is further passed to artificial intelligence, data analytics, and supply chain operations that impact everything from global commerce to our daily lives.
Cybercriminals use smart home devices to enter a network and infiltrate other devices. They can also be exploited to threaten the physical safety of people. Hence, securing a smart home from IoT cyber threats has become more important than ever.
It is critical to develop and follow best security practices to protect your devices, users, and network from cyber threats. In this article, check below the common Internet of Things (IoT) mistakes you should avoid, security tips to secure your home and tools to secure IoT devices.
Common Internet of Things (IoT) Mistakes To Avoid
1. Using the same password for everything
2. Skipping updates because “it’s working fine”
3. Giving apps or devices too many permissions
4. Not checking where your data is going
5. Leaving devices connected even when not in use
IoT Security Measures Tips
Use Strong, Unique Passwords
Leaving default usernames and passwords unchanged is one of the easiest ways for attackers to gain access. One of the most effective ways to secure a smart home is by strengthening passwords. Always create strong and unique passwords for each device, especially critical services like security cameras and smart locks.
Firmware/Software Update
Another key step is keeping devices updated. Manufacturers frequently release firmware updates to patch security vulnerabilities, but users often ignore or delay these updates. Automatic updates should be enabled when available to ensure devices are protected against the latest threats. If automatic updates are not an option, users should regularly check for updates manually.
Two-factor authentication (2FA)
For devices and apps that support it, enabling two-factor authentication (2FA) adds an additional layer of security. It ensures that even if someone gets access to your password, they can’t log in without a second factor. You might verify your identity by using codes or biometric methods, such as facial recognition or a fingerprint, that are already set up on your phone or tablet.
Secure Your Router
Home Wi-Fi networks also play a crucial role in IoT security. An unsecured or poorly configured network can expose all connected devices. Ensure your router uses strong encryption protocols such as WPA3 encryption to keep your wireless connections secure. Also, change the default router name and password.
Segment Networks
One often-overlooked security measure is network segmentation. Set up a separate guest network for IoT devices, limiting their access to your main devices and data. This ensures that even if one device is compromised, critical personal data remains protected.
Monitor Your Privacy Settings
Look at the privacy settings on your smart devices in your home. The manufacturer is opting you in to strong privacy settings by default. But if you can control these settings, such as whether you can prevent your information from being sent to the manufacturer or how long your video or audio will be saved, adjust them to your comfort level.
Disable Unused Features
Review your device’s settings and turn off any features that aren’t essential to your daily usage. Many IoT devices come with features like Bluetooth, remote access, voice activation or UPnP (Universal Plug and Play) that you may not need. If you don’t use these features, disable them to reduce your attack surface.
Purchase From Reputable Brands
Investing in devices from reputable brands that prioritise security is another important thing to keep in mind. While cheaper alternatives may be appealing, they often lack regular updates and proper security safeguards. Checking for certifications and reading security reviews before purchasing can help consumers make safer choices.
Tools to Secure IoT Devices
You can also purchase some smart tools that can do the heavy lifting for you:
ForeScout Platform: It helps monitor all devices on your network. The device lets you know what’s connected and notify about any odd behaviour.
Microsoft Defender for IoT: This device scans for vulnerabilities and gives you alerts if something seems off.
Asimily: Good for health-related IoT, like smart thermometers or medical devices. It looks for risks specific to those.
AWS IoT Device Defender: If you’re using Amazon’s cloud services, this device keeps an eye on configurations and unusual activity.
