Explanation
Port 443 is used by HTTPS (Hypertext Transfer Protocol Secure), which encrypts web traffic using SSL/TLS, making it a secure protocol. Port 20 is used for FTP data transfer and is not secure. Port 23 is used by Telnet, which transmits data in plaintext and is not secure. Port 445 is used for SMB (Server Message Block) over IP, which is not inherently secure unless additional security layers are applied. Only port 443 provides secure, encrypted communication by default.
