The Internet of Things (IoT) is all around us, changing how we live and work every day. It refers to a network of devices—like smart speakers, watches, and home appliances—that connect to the internet to share information and work together. These devices make life easier and more fun. But just like any technology connected to the internet, they also come with some security risks.
What Are IoT Security Concerns?
Weak Passwords
Many IoT devices come with default usernames and passwords, like “admin” or “12345.” If you don’t change them, hackers can easily guess these passwords and take control of your devices.
Personal Data Risks
IoT devices collect a lot of personal information, like your location, voice recordings, or health data. If hackers access this information, they could misuse it.
Outdated Software
Just like phones, IoT devices also need updates to fix bugs and improve security. If a device isn’t updated regularly, it might have security flaws that hackers can exploit.
Network Attacks
Since IoT devices are connected to your Wi-Fi network, a hacker who accesses one device could get into other devices on the same network, like your computer or smartphone.
How Can You Stay Safe?
Step 1: Use Strong Passwords
When setting up a new device, always change the default password to something unique. Avoid using the same password for multiple devices—if one gets hacked, the rest remain safe. Create strong passwords by using a mix of letters, numbers, and symbols to make them difficult to guess.
Step 2: Check Your Device’s App
Each IoT device has its own app for managing settings and security features. Depending on your device, check apps like SmartThings (Samsung), Imou Life (security cameras), Google Home, Alexa, or your device manufacturer’s app. Look for options like Two-Factor Authentication (2FA), remote access control, activity logs, and privacy settings to keep your device secure.
Step 3: Enable Security Features
Enable Two-Factor Authentication (2FA) if your device supports it. This adds an extra layer of protection by requiring a code sent to your phone in addition to your password. Also, set up a guest network for your IoT devices so they don’t share the same network as your personal computer or phone.
Step 4: Update Regularly
Keeping your devices updated is one of the easiest ways to stay secure. Updates often fix security flaws that hackers can exploit. If possible, enable automatic updates so you don’t have to check manually.
Step 5: Be Careful with What You Share
IoT devices collect data, but not all of it is necessary. Review your device’s privacy settings and limit data sharing. For example, a smart light doesn’t need access to your location—adjust its settings to protect your personal information.
Step 6: Turn Off Devices When Not in Use
If you’re not using a device for a while, consider turning it off or disconnecting it from the internet. Also, disable features you don’t need, such as remote access or voice activation, to reduce security risks.
Step 7: Secure Your Wi-Fi Network
Since all your IoT devices connect to your home network, securing your Wi-Fi is essential. Change your router’s default username and password, enable WPA3 or WPA2 encryption, and consider hiding your network name (SSID) so it's less visible to outsiders.
Step 8: Be Cautious with Third-Party Apps and Integrations
Only install apps from trusted sources like the Google Play Store or Apple App Store. When connecting third-party apps or services to your IoT devices, check what permissions they request and make sure they only access what they truly need.
Step 9: Monitor Device Activity
Some IoT devices keep activity logs, which can help you spot unusual access. Check logs regularly and enable notifications for login attempts or changes to your device’s settings to stay informed about potential security threats.
Step 10: Educate Yourself and Your Family
Cybersecurity is always evolving, so stay informed about new threats and best practices. Make sure everyone in your household understands the basics of online security, like not sharing passwords and recognizing suspicious activity.
