→ A cross-device system is quite vulnerable. First of all, we need to introduce you to the three main factors affecting IoT security:
IoT regulations. No single IoT security standard covers all sections of the IoT market (devices, networks, applications).
Built-in functions. Many devices have weak or no security features. In the commercial realm, manufacturers of IoT devices often prioritize performance and price over device security. At the same time, IoT users often ignore IoT security in favor of cost.
Data confidentiality. IoT devices track our personal lives, including location and health. Many manufacturers don’t have transparent policies explaining how they use personal data.
