Secure your Internet of Things (IoT) devices
Strong Passwords and Authentication:
- Change default credentials: This is the first and most crucial step. Many IoT devices come with weak preset passwords that are easy to find online. Replace them with strong, unique passwords for each device. Don't reuse passwords across devices.
- Enable Multi-Factor Authentication (MFA): Whenever possible, use MFA to add an extra layer of security beyond just a password. This could involve a code from your phone or a fingerprint scan.
- Updates and Security Patches
• Proactive Patch Management: Just like any other software, IoT devices need regular updates to fix security vulnerabilities. Stay informed about updates from your device manufacturers and install them promptly.
- Network Segmentation
• Isolate IoT devices: Consider creating a separate network for your IoT devices to minimize the risk of them compromising your main network if they get hacked.
- Device Monitoring
• Stay vigilant: Keep track on your IoT devices for any suspicious activity. This could involve monitoring network traffic or unusual behaviour from the devices themselves.
• Inventory Your Devices: Keep track of all the IoT devices on your network. This will help you identify suspicious activity or unauthorized devices.
• Monitor Network Activity: Monitor your network for unusual activity from your IoT devices. Firewalls and intrusion detection systems (IDS) can help with this.
- Additional Security Measures
• Disable Unused Features: Turn off any features on your IoT devices that you don't use. This reduces the device's attack surface.
• Research Before You Buy: When considering new IoT devices, research their security features and reputation. Look for devices with a history of strong security practices and ongoing support from the manufacturer.
By following these practices, you can significantly improve the security posture of your IoT devices and make your home network less vulnerable to cyberattacks.
