The implementation of an IoT SSH Web example solution involves several architectural considerations. The choice of hardware, the software used for the web interface, the network architecture, and the security protocols all play a critical role in determining the success of the project. The architecture usually incorporates the IoT devices themselves, a gateway or edge device, a backend server, and the web interface. The IoT devices communicate with the gateway, which in turn handles the connection to the internet. The backend server stores and processes the data received from the gateway, and serves the web interface to the end-user.
Security is paramount. Each component in the system represents a potential point of vulnerability. Ensuring the security of the IoT devices, the gateway, the SSH connections, the web interface, and the data transmission requires a multi-layered approach. This includes:
