I recently gain interest in both IoT and cybersecurity. I was amazed that the designers of these devices, which can vary in function and prices, almost always poorly implement security. here is an article related to these subject :
An alarm with no mecanism against bruteforce : https://www.pentestpartners.com/security-blog/hack-demo-video/disabling-wireless-alarms-issue-3-pin-brute-force/
There is several exemples of bad practices regarding the security of this kind of devices. So my question is the following :
Why is the security so often neglected in this field ? Is because of a lack a skill in the domain ? Is it because of laziness ?
