CompTIA Project+ (PK0-005)Basics of IT and GovernanceMedium
A project involves deploying a new public-facing web application that will handle customer registrations and process online orders. During the planning phase, the project manager identifies that the application must ensure data integrity, confidentiality, and authenticity for all communication between users and the server. Which protocol is MOST appropriate to meet these requirements?
- AHTTP
- BSMTP
- CFTP
- DHTTPS
Show answer & explanationAnswer & explanation
Correct answer: D. HTTPS
HTTPS (Hypertext Transfer Protocol Secure) encrypts communication between the client and server, ensuring data confidentiality, integrity, and authenticity through SSL/TLS, which is essential for public-facing web applications handling sensitive data.
Why the other options are wrong
- A. HTTP transmits data in plain text, offering no confidentiality, integrity, or authenticity.
- B. SMTP is used for sending email and is not designed for secure web application communication.
- C. FTP is used for file transfer and typically lacks encryption, making it unsuitable for sensitive web communication.
HTTPS (Hypertext Transfer Protocol Secure)
A secure version of HTTP that uses SSL/TLS encryption to protect communication between a web browser and a website, ensuring data confidentiality, integrity, and authenticity.
- Encrypts web traffic using SSL/TLS.
- Protects against eavesdropping and tampering.
- Essential for e-commerce, banking, and sensitive data transfer.
Memory trick: HTTPS is HTTP with a secure 'S'eal of approval.
