Choosing Smart Home Gadgets: A Security-Focused Guide

(This article was originally published on March 27, 2019 and has been updated.)

Smart home devices offer undeniable convenience, but their internet connectivity introduces security vulnerabilities. While the benefits of the Internet of Things are significant, these devices are essentially computers, inheriting similar security risks. Past incidents, such as the discovery of unencrypted WiFi passwords stored in LIFX smart bulbs, highlight these concerns.

A compromised device on your network can act as a gateway, potentially affecting other linked gadgets controlled by the same app. This could lead to significant security breaches, even allowing unauthorized access to your home. Poorly secured IoT devices can also be weaponized, as demonstrated by botnets leveraging insecure internet cameras.

While extreme scenarios remain largely theoretical, proactive measures are crucial. Understanding the risks and choosing wisely can minimize vulnerabilities.

Prioritize Your Needs and Understand the Risks

Many smart devices lack truly innovative functionality. Consider whether a smart device offers genuine value beyond what your existing devices already provide. Before purchasing, assess your needs and the potential consequences of compromise. Will the device store personal data? Will it be used for online purchases? And most importantly, how much trust do you place in the manufacturer?

Scrutinize Security Features

Before purchasing any internet-connected device, thoroughly investigate its security features, setup process, and settings. Look for secure connections (HTTPS) and Transport Layer Security (TLS) to protect data in transit. Examine app permissions and download apps only from reputable app stores like Apple's App Store or Google Play. Verify the ability to set strong, unique passwords and avoid devices with hard-coded passwords. Disable remote access features if possible. Prioritize devices with end-to-end encryption for secure data transmission.

Choose Reputable Brands

While brand recognition doesn't guarantee security, established brands are more likely to address vulnerabilities through firmware updates and public acknowledgements. Regular app updates are crucial for patching security flaws. Pay attention to end-of-life announcements for devices, as support cessation increases security risks.

Conclusion

Smart homes offer significant advantages, but security must remain a top priority. By carefully considering your needs, thoroughly researching security features, and choosing reputable brands, you can significantly reduce the risks associated with smart home technology. Remember that even the most secure devices eventually become obsolete, necessitating responsible disposal or replacement.
