Protect Yourself from IoT Hacks
From smart refrigerators and thermostats to fitness trackers and voice assistants, the Internet of Things (IoT) has revolutionized modern living. But as more of our daily devices become connected to the internet, they also become potential entry points for hackers. Whether you're a homeowner or a business, understanding how to secure your IoT devices is critical to protecting your data, privacy, and infrastructure.
Here we explore practical steps you can take to protect yourself from IoT hacks and ensure your connected environment remains safe and secure.
Change Default Usernames and Passwords Immediately
Many IoT devices come with default login credentials that are widely known or easily guessable. Hackers often scan networks looking for devices that still use these defaults, making them an easy target.
Change the default username and password to something strong and unique as soon as you set up your device. Use a combination of upper and lowercase letters, numbers, and special characters. Avoid using common passwords like "admin" or "123456."
Keep Device Firmware Up to Date
Just like your smartphone or laptop, IoT devices run on software that occasionally needs updates to patch vulnerabilities and improve performance. However, not all devices update automatically.
Enable automatic updates where available, or set a reminder to manually check the manufacturer’s website for firmware updates. Neglecting updates can leave known security holes open to exploitation.
Segment Your Network
Connecting all your devices to a single network makes it easier for hackers to pivot from one compromised device to another.
Use a separate network or VLAN (Virtual Local Area Network) for your IoT devices. Many modern routers support guest networks—ideal for smart devices—which can keep them isolated from your main computers and sensitive data.
Disable Unused Features
IoT devices often come loaded with features like remote access, Bluetooth, and UPnP (Universal Plug and Play) that you may never use.
Review your device settings and disable any unnecessary features. The fewer services your device is running, the smaller the attack surface.
Secure Your Wi-Fi Network
A weak Wi-Fi network is like an unlocked front door to all your connected devices.
Use WPA3 encryption if your router supports it (WPA2 at a minimum). Change your default SSID (network name) and router admin password. Avoid common names like "HomeWiFi" that can give away your network's identity.
Use Firewalls and Network Security Tools
A firewall acts as a gatekeeper, monitoring and controlling incoming and outgoing traffic.
Make sure your router includes a built-in firewall and that it's turned on. Consider adding a dedicated network firewall or a security-focused router that provides deeper insights and threat detection for IoT activity.
Monitor Your Connected Devices
Do you know how many smart devices are currently connected to your network? Most people don’t, and hackers count on that.
Use your router’s admin panel or a network monitoring app (like Fing or GlassWire) to regularly review and verify connected devices. If you see an unfamiliar device, investigate immediately.
Enable Multi-Factor Authentication (MFA)
If an IoT device or associated app supports MFA, enabling it adds an extra layer of protection.
Set up MFA using your smartphone, an authentication app, or a security key. Even if someone obtains your password, MFA can prevent them from logging in.
Buy from Trusted Manufacturers
Not all IoT devices are created equal. Some low-cost options skimp on security, have poor update support, or lack transparency about data usage.
Stick with reputable brands that publish their security policies, offer regular firmware updates, and have good customer support. Check product reviews and security reports before purchasing.
Educate Yourself and Your Household or Team
Technology is only as secure as the people using it. Human error, such as clicking a phishing link or neglecting updates, often leads to breaches.
Stay informed about emerging IoT threats. For businesses, conduct regular cybersecurity training for employees to reinforce best practices around device usage and password hygiene.
Invest in IoT Security Solutions
There are now platforms specifically designed to secure IoT environments. These tools offer real-time monitoring, device behavior analytics, and automated threat response.
Explore solutions like Bitdefender Box, Cujo AI, or enterprise-grade options that help detect and mitigate unusual activity from IoT devices.
Why IoT Security Matters More Than Ever
According to a 2024 report by Palo Alto Networks, IoT devices now account for over 30% of all devices on enterprise networks—and more than 50% of those devices are vulnerable to medium or high-severity attacks. The growth of connected tech in homes and businesses means the attack surface is only getting larger.
Unlike traditional PCs, many IoT devices have limited built-in security and minimal user interfaces, making them harder to monitor and secure.
By implementing these best practices, you can protect yourself, your family, or your business from potentially devastating IoT-based cyberattacks.
