The USB port of the Nest Thermostat is not tightly secured and appears to be vulnerable to hacking. The Nest thermostat tracks your location, availability, and unavailability at your residence, and it appears to be a piece of very risky and dangerous information that can be breached.

Another factor that is riskier from the access of the Nest Thermostat is hackers having access to your Wi-Fi connection. As all of the Nest smart products work through the Wi-Fi connection, they can be controlled by someone else if hacked along with the access of personal information.

Controlling Security Violations

The top and foremost precaution one can take to protect and safeguard Nest Thermostat is ensuring no one can touch the device or has physical access to it. If this can be achieved, there are way fewer chances of the device getting hacked.

ARP spoofing detection software can be used to identify and rule out the identity and the IP address of the hacker. If Anti-ARP detection software is also applied with the ARP detection software, there will be no chance for the hacker to get notified of any kind of alert regarding its identity tracking.

In most cases, security issues and violations are caused by unsecured passwords and not by the security breaches of Nest products. You can protect the password by enabling two-factor authentication to eliminate the chances of attack and enhance the device’s security.
