Which of the following protocols is commonly used for secure remote access to a network, providing encryption and authentication?

The protocol commonly used for secure remote access to a network, providing encryption and authentication, is Secure Shell (SSH).

Here are the steps to explain why:

1. Secure Shell (SSH): This is a cryptographic network protocol for operating network services securely over an unsecured network. It provides strong password authentication and public key authentication. It also provides encrypted data communications between two computers connecting over an open network such as the internet.

2. Encryption: SSH uses public-key cryptography to authenticate the remote computer and allow the remote computer to authenticate the user, if necessary. It is designed to provide secure encryption, robust authentication, and data integrity.

3. Authentication: SSH provides two different types of authentication - password and public key. Password authentication is the same as logging in to your computer. Public
