- Reboot your devices regularly. If the IoT device starts to become slow or inoperable, it may mean that viruses are present. Some malware is stored in memory and can be easily removed by a device reboot, that is, by turning the device off and on. If the device continues to be slow or inoperable after a reboot, try a factory reset. Be aware that implementing a factory reset may wipe your user data and personalised settings.
- Apply regular updates. Some devices apply updates automatically. For those that don’t, regularly check with the manufacturer and apply updates when they become available. When updates are no longer available for your device, consider upgrading to a newer device where updates are available. Devices that don’t have access to security updates will not be protected if new vulnerabilities are discovered, and these devices may become a risk to your network, your privacy and your data.
- Turn off your device when it is not in use. Leaving unused and unmonitored devices powered on and connected to your Wi-Fi network for extended periods can increase the likelihood of your devices being attacked. One option to achieve this automatically is to use a power outlet timer to only provide power to the device during the specified hours.
- Watch for a significant increase in your monthly internet usage or bill. Significant increases in internet usage or billing charges can indicate that your device has been compromised. Implementing a factory reset and changing the password on your IoT device may assist (but remember that a factory reset may wipe your user data and personalised settings).
