System & Software Vulnerabilities
Some smart devices may not implement encryption fully, even if they advertise the use of encryption. Lapses in encryption leave you open to possible disruptions or possible intrusions (‘sniffing’).
Consider how well the smart system software stays up to date, is it automatic or do you have to download patches? An excellent security device or system will notify you of pending updates or one that automatically updates itself.
Smart home devices have software vulnerabilities just like smartphones, tablets, or PCs. You can do an online search on the device model and check for published vulnerabilities and how many have been fixed.
Timely updates will, however, keep smart devices functioning properly and reduce vulnerability.
Be sure to opt for a system that allows you to change the password on installation.
