Which abbreviation stands for Secure Shell?

Which abbreviation stands for Secure Shell?

• A. SSID
• B. SSH
• C. SSL
• D. SID

Answer: (B)

Understanding common network protocol acronyms helps you pick the right tool for secure remote access. SSH stands for Secure Shell and is specifically designed to provide a secure, encrypted channel for remote command-line access and administration. This protects credentials and commands from eavesdropping and tampering, which is essential when managing systems over a network. SSH typically runs over port 22 and also supports secure file transfers via SCP or SFTP, using strong authentication methods such as public key authentication. The other terms refer to different concepts: SSID is the wireless network name you connect to, not a secure remote access protocol; SSL (now largely TLS) is used to encrypt web traffic and other communications to protect data in transit, not for interactive remote shell sessions; SID is a Windows Security Identifier used to uniquely identify users or groups, not for securing remote connections.
