Explanation
The standard port that is typically used to share data securely with partners via the Internet is Transmission Control Protocol (TCP) port 22. TCP port 22 is the default port for Secure Shell (SSH), a protocol that provides encrypted and authenticated communication between systems over an unsecured network. SSH can be used to securely transfer files, execute commands, or tunnel other protocols. SSH uses public key cryptography to authenticate the systems and users, and symmetric cryptography to encrypt the data. SSH can also compress the data to reduce the bandwidth usage and improve the performance. SSH is widely used for remote administration, file transfer, and network management.
