What is an IoT?

The Internet of Things (IoT) is a network of physical devices, appliances, vehicles, and other items embedded with electronics, software, and sensors. These devices are able to connect and exchange data with each other over the internet. This allows them to collect and share data, creating opportunities for more efficient and automated systems.

Here are some examples of IoT devices:

  • Smart home devices, like refrigerators
  • Wearables, like smartwatches and fitness trackers
    •  

      • Strong passwords and authentication: This is the most crucial step. Change the default credentials that come with the device to a strong, unique password. Avoid using the same password for multiple devices. If possible, enable multi-factor authentication (MFA) for added security.

      • Software updates: Just like any other software, IoT devices are susceptible to vulnerabilities. Keeping your device's firmware up-to-date with the latest security patches is essential. Enable automatic updates if available, or check for updates regularly from the manufacturer's website.

      • Disable unused features: Many IoT devices have features you might not be using. Disable any features that could be potential security risks.

      • Guest network: Consider placing your IoT devices on a separate network from your main devices (computers, phones etc). This way, even if an attacker compromises an IoT device, they won't be able to access your other devices. Many routers allow you to set up guest networks for this purpose.

      • Secure router: Your Wi-Fi router is the gateway to your network. Ensure it has a strong password and WPA2 encryption enabled.

      • Device research: Before purchasing an IoT device, research its security features. Look for devices from reputable manufacturers with a good track record of security updates.

      By following these steps, you can significantly improve the security of your IoT devices and protect yourself from potential cyberattacks.
