A strong IoT security model lets both individuals and organizations protect their network/information in all aspects. It assures them to meet their application requirements through unbreakable security mechanisms. Mainly, it works under the principle of cryptography technology. In this, it provides sophisticated approaches to fight against network attacks, threats, and vulnerabilities. For instance: if it detects the compromised vulnerable systems then immediately it isolates those systems from the network as a security measure.

These kinds of devices are collectively referred as the heterogeneous devices. So, the security technologies are needed to cope with all devices in regardless of their type and features.  For instance: the classic security approaches are not well-suited for current low resourced constrained devices. 

As mentioned earlier, the IoT security model is necessary to focus on each layer of data transmission to craft IoT Security Thesis.
