What does SSH stand for?

SSH stands for Secure Shell. It is a cryptographic network protocol that allows secure communication between a client and a server over an unsecured network. SSH is commonly used for remote login to systems and executing commands, enabling users to access another computer securely, as it encrypts the data being transmitted to prevent eavesdropping and tampering.

The significance of SSH lies in its ability to provide a secure channel over an unsecured network, making it a foundational technology in network administration and secure data transmission. By using strong encryption methods, SSH ensures that sensitive information remains confidential even when transmitted over potentially compromised networks.

Other terms listed do not represent recognized standards in networking or security. For instance, "Secure Socket Host" and "Secure Service Hub" do not relate to any common security protocols or services, and "Simple System Host" does not accurately describe a technology related to secure communications. The clarity and relevance of "Secure Shell" to secure remote access underscore why it is the appropriate choice.
