Implementing Cellular IoT Solutions for Digital Transformation
By :

The need for an end-to-end security solution that is adaptable to the various IoT connectivity models and varied IoT device types is an essential requirement in any enterprise IoT solution. Security needs to be deployed at various points in the ecosystem, and these security solutions need to be coupled to provide multiple layers of security. The best approach is a multi-layered security framework that covers all points in the IoT ecosystem, as shown in Figure 7.2.

In reviewing this multi-layer security approach, let us start with the device endpoint layer.
The physical security of the IoT device is a critical component of any IoT solution. Ensuring that devices are not compromised can help ensure that the data from them is not corrupted. There are various device-side security solutions available today. Some examples of these are as follows:
