1. What is SSH and Why is it Important for IoT?

Secure Shell, commonly known as SSH, is a network protocol that provides administrators with a secure way to access a remote computer. It is widely used for managing systems and applications remotely, due to its strong encryption and authentication mechanisms. In the context of IoT, SSH becomes crucial due to the need for secure communication between devices that are often dispersed across various locations.

SSH operates on a client-server model where the client initiates a connection to the server. Once the connection is established, data is transmitted in an encrypted format, ensuring that it cannot be intercepted or altered by malicious actors. This is particularly important in IoT environments where devices often transmit sensitive data that could be exploited if intercepted.
