When you design an IoT project, you should also think about security features in your IoT project. Security features can enforce security in an IoT project. The following are some security features that could be implemented in your IoT projects:

• Securing IoT devices
• Supporting a secure protocol such as TLS/SSL
• Secure gateway

IoT device should be designed in order to support secure protocol. Some MCU chips support secure protocols such as TLS/SSL. You can select one of those chips in your IoT device design.

Sometimes, IoT devices connect to a server through the internet. This operation usually needs a gateway. In this scenario, you should perform a secure gateway to ensure secure communication between the IoT devices and the server.
