Homeowner Takes Control: Smart Devices Cut Off from Internet

URGENT UPDATE: A homeowner has successfully secured their smart home by cutting off all Internet access to connected devices, a critical move against potential cyber threats. The action follows rising concerns over unpatched vulnerabilities in Internet of Things (IoT) technology, which can leave homes exposed to attacks.

With the increasing number of poorly secured smart devices, the risk of becoming part of a botnet, like the notorious Mirai, is more pressing than ever. Automated scanning and AI advancements have heightened the dangers lurking in connected devices as of October 2023. This homeowner’s innovative approach could serve as a blueprint for others seeking to protect their own smart homes.

After realizing the potential security holes in their smart home setup, the homeowner took action by blocking all IoT devices from accessing the Wide Area Network (WAN). This involved a significant overhaul of their home network, including adjustments to firewall settings and integrating devices into a local management system, Home Assistant.

The shift required setting up a dedicated Virtual Local Area Network (VLAN) specifically for IoT devices, ensuring that these devices could not communicate freely with the Internet. By utilizing local control protocols, such as Zigbee, the homeowner eliminated many security concerns associated with cloud dependence.

Notably, the integration of Tailscale has enabled the homeowner to regain remote access to their smart home while maintaining security. By connecting Home Assistant with Tailscale, the homeowner can control their devices from anywhere, without exposing them to external threats. The home network is now fortified with strict firewall rules governing device communications, reducing vulnerability significantly.

“I don’t trust most devices on my home network,” said the homeowner.

“Implementing my own access tools gives me peace of mind while allowing me to manage my smart home remotely.”

The process involved setting up multiple layers of protection, including a local Language Model (LLM) for voice control and automation systems that activate when the homeowner leaves the house. This ensures that while the homeowner enjoys the convenience of controlling their smart home on the go, security remains a top priority.

This development comes at a crucial time as more households adopt smart technology, making them potential targets for cybercriminals. The homeowner’s experience highlights the importance of taking proactive measures to secure smart devices—a lesson that could resonate widely in today’s digital landscape.

For those considering a similar security overhaul, the homeowner suggests beginning with a comprehensive understanding of their smart devices and implementing a local control system. With growing concerns over IoT security, this approach could very well become the standard for smart home users everywhere.

As smart homes continue to proliferate, the homeowner’s strategy serves as a beacon of hope for those looking to balance convenience with security. The implications of this shift are significant, not just for individual users but for the entire smart home ecosystem.

Stay tuned for further updates as more homeowners adopt similar strategies to safeguard their digital spaces.
