A project is deploying a new web application that will handle sensitive customer payment information. The project manager needs to ensure that all data transmitted between the user's browser and the web server is encrypted to prevent eavesdropping. Which protocol is primarily responsible for securing this communication?
- AFTP
- BSMTP
- CHTTPS
- DHTTP
Show answer & explanationAnswer & explanation
Correct answer: C. HTTPS
HTTPS (Hypertext Transfer Protocol Secure) is the secure version of HTTP, which uses SSL/TLS to encrypt communication between a web browser and a server, protecting data from eavesdropping and tampering.
Why the other options are wrong
- A. FTP (File Transfer Protocol) is used for transferring files and is not inherently secure for web browsing.
- B. SMTP (Simple Mail Transfer Protocol) is used for sending email, not for securing web browser communication.
- D. HTTP (Hypertext Transfer Protocol) transmits data in plain text, making it vulnerable to eavesdropping.
HTTPS
A secure version of HTTP that uses an SSL/TLS certificate to encrypt communication between a web browser and a web server.
- Ensures data confidentiality and integrity during web communication.
- Prevents eavesdropping and tampering.
- Indicated by a padlock icon in the browser address bar.
Memory trick: For secure web, the 'S' in HTTPS means safe.
