What protocol is used for secure remote access and terminal communications?

SSH, or Secure Shell, is the protocol designed specifically for secure remote access and terminal communications. It provides a secure channel over an unsecured network by using encryption, which is crucial for protecting the confidentiality and integrity of data exchanged between the client and the server. This makes it an ideal choice when accessing systems remotely, as it prevents eavesdropping, connection hijacking, and other forms of network attacks.

The advantages of SSH include secure file transfer capabilities, terminal session encryption, and the ability to manage network devices securely. Its use of key-based or password-based authentication further enhances security, making it a robust option for organizations needing remote access solutions. This solid foundation of security is why SSH is considered a standard in secure communication protocols.
