The Expanding Attack Surface of IoT Devices
As our lives become increasingly connected to the internet, the attack surface available to threat actors continues to expand. Today, it’s common to have household devices like thermostats communicating online just like our smartphones. These Internet of Things (IoT) devices are designed to make our lives more convenient and enjoyable, but they can also pose significant risks to our online security. Each home network needs essential steps for IoT security
Why IoT Devices Are Vulnerable to Attacks
Imagine your home as a locked door with an open window. While the door might be secure, a bad actor can still crawl through the window and gain access. In this analogy, your home router is the lock, and the open window could be any of your connected devices: thermostats, security cameras, baby monitors, lighting controls, and many others. It only takes one vulnerable device to compromise your entire network.
Essential Steps to Protect from IoT Threats:
- Update Your IoT Devices Regularly
Don’t ignore pending updates. These updates often contain crucial security patches that close vulnerabilities and keep bad actors out. - Segregate Your Home Network
Securely build your network and ensure that your IoT devices are on a different segment than your other devices. This will help contain a breach if an IoT device gets compromised, preventing it from spreading to the rest of your home network. - Use a VPN for Enhanced Security
A Virtual Private Network (VPN) encrypts communications between your smart devices and the internet. While it doesn’t close the open window entirely, it prevents attackers from intercepting your data. - Stay Vigilant for Warning Signs of Breaches
Many attacks have warning signs. For instance, if your baby monitor’s activity light is on when you aren’t connected, or your security camera frequently needs rebooting, these could be indicators of a security breach. Address such issues immediately.
Conclusion: Stay Safe in the Connected World
By following these essential steps for IoT security, you can reduce your risk and enjoy the benefits of IoT devices without compromising your security. Stay informed, stay updated, and stay vigilant to protect your connected home.
