SSH encodes the packets, making it impossible for anyone to observe your activities. The default SSH client allows you to connect to Linux workstations through a secure channel, and it defaults to TCP port 22.

It offers a secure route over an unprotected network, connecting an SSH client program to an SSH server in a client-server architecture.
They are unsafe since they transmit the user’s password in plaintext. Old methods for accomplishing these actions, such as telnet do not have these capabilities. Secure Shell (SSH) protocol is used to manage or transmit data between computers through the internet. It encrypts all client-server traffic to prevent eavesdropping, connection hijacking, and other types of attacks. It allows you to access your machine remotely and execute operations securely.
