Explanation
SSH (Secure Shell) is the industry-standard protocol for secure remote command-line interface (CLI) access because it encrypts all communication, protecting data integrity and confidentiality.
Common mistakes.
- A. HTTPS is used for secure web-based access and management, not typically for direct command-line interface access.
- B. HTTP is an insecure protocol used for web-based access and management; it is not typically used for direct command-line interface access and does not provide encryption.
- C. Telnet is an insecure protocol for command-line interface access as it transmits all data, including usernames and passwords, in plaintext, making it vulnerable to interception.
