What safety measure should be considered when using smart home devices?

Keeping all firmware regularly updated is crucial for the safety and security of smart home devices. Firmware updates often include patches for security vulnerabilities that could be exploited by malicious actors. Without these updates, devices may be susceptible to attacks, leaving the entire network at risk.

Additionally, manufacturers often release updates to enhance functionality and improve user experience, making regular updates doubly beneficial. Thus, ensuring that all smart home devices have the latest firmware significantly mitigates potential security threats and helps maintain a secure smart home environment.

The other choices present practices that compromise security, such as using public Wi-Fi, employing outdated password practices, and granting unrestricted access, which can all increase vulnerability to breaches and unauthorized access.
