A project is deploying a new web application that will handle sensitive customer payment information. To ensure the highest level of security for data transmitted between the user's browser and the web server, which protocol should the project manager ensure is implemented?
- AFTP
- BHTTP
- CSMTP
- DHTTPS
Show answer & explanationAnswer & explanation
Correct answer: D. HTTPS
HTTPS (Hypertext Transfer Protocol Secure) encrypts communication between a web browser and a website, protecting sensitive data like payment information from eavesdropping and tampering during transmission.
Why the other options are wrong
- A. FTP (File Transfer Protocol) is used for transferring files but is generally unencrypted and not for web browsing.
- B. HTTP (Hypertext Transfer Protocol) transmits data in plain text, making it insecure for sensitive information.
- C. SMTP (Simple Mail Transfer Protocol) is used for sending email, not for securing web application communication.
HTTPS
Hypertext Transfer Protocol Secure (HTTPS) is an extension of HTTP that provides secure communication over a computer network. It encrypts data transmitted between a web browser and a server, protecting against eavesdropping and tampering.
- Uses SSL/TLS for encryption.
- Identified by 'https://' in the URL and a padlock icon.
- Essential for e-commerce, banking, and any site handling sensitive data.
Memory trick: HTTPS Hides The Private Stuff.
