A developer is creating a web application that needs to securely transmit sensitive user data, such as login credentials and financial information, between the client's browser and the server. Which protocol is essential for ensuring this secure communication?
- AFTP
- BHTTPS
- CHTTP
- DSMTP
Show answer & explanationAnswer & explanation
Correct answer: B. HTTPS
HTTPS (Hypertext Transfer Protocol Secure) is the secure version of HTTP. It uses SSL/TLS encryption to protect data in transit, making it essential for transmitting sensitive information securely over the internet. HTTP, FTP, and SMTP do not provide inherent encryption for data in transit.
Why the other options are wrong
- A. FTP (File Transfer Protocol) is used for file transfers but does not inherently encrypt data.
- C. HTTP (Hypertext Transfer Protocol) transmits data in plain text, making it insecure for sensitive information.
- D. SMTP (Simple Mail Transfer Protocol) is used for sending email and is not directly involved in securing web application data transmission.
HTTPS (Hypertext Transfer Protocol Secure)
A secure version of HTTP that uses SSL/TLS to encrypt communication between a web browser and a website, protecting sensitive data.
- Uses encryption (SSL/TLS) for data in transit.
- Ensures data integrity and confidentiality.
- Identifies the website's authenticity.
- Standard for secure web browsing and transactions.
Memory trick: HTTPS protects your secrets, keeping web data safe and sound.
