Why each option
SSH and HTTPS are both protocols that use encryption to protect data in transit, while Telnet, POP3, and FTP transmit data in cleartext.
Telnet transmits all data, including usernames and passwords, as unencrypted cleartext over the network.
SSH (Secure Shell) encrypts all session data including authentication credentials using asymmetric and symmetric cryptography, making it the secure replacement for Telnet.
POP3 on port 110 sends credentials and email content in plaintext; encrypted email retrieval requires POP3S on port 995.
FTP on ports 20/21 transmits both credentials and file data in cleartext; secure alternatives include FTPS and SFTP.
HTTPS wraps HTTP inside TLS/SSL, encrypting all data exchanged between the client and web server, protecting confidentiality and integrity of web traffic.
