A network administrator is troubleshooting an issue where users are unable to access a newly deployed web application. Upon investigation, they discover that the firewall is blocking traffic on a specific port. Which of the following common network ports is typically used for secure web traffic (HTTPS)?
- APort 443
- BPort 80
- CPort 21
- DPort 23
Show answer & explanationAnswer & explanation
Correct answer: A. Port 443
Secure web traffic (HTTPS) uses TLS/SSL encryption and operates over port 443. This port is crucial for protecting sensitive data exchanged between a web browser and a server.
Why the other options are wrong
- B. Port 80 is used for HTTP (Hypertext Transfer Protocol), which is unencrypted web traffic.
- C. Port 21 is commonly used for FTP (File Transfer Protocol), not secure web traffic.
- D. Port 23 is commonly used for Telnet, a plaintext remote access protocol, not secure web traffic.
HTTPS Port
Port 443 is the standard Transmission Control Protocol (TCP) port used for HTTPS (Hypertext Transfer Protocol Secure) communication.
- Encrypts web traffic using TLS/SSL.
- Ensures data confidentiality and integrity.
- Essential for secure online transactions and sensitive data exchange.
Memory trick: Secure web traffic 'forty-four-three' is the key to privacy.
