A project manager is overseeing the deployment of a new corporate intranet. During the planning phase, the team decides that all communication with the intranet should be encrypted to protect sensitive internal information from eavesdropping. Which protocol is essential for achieving this secure communication over HTTP?
- ASMTP
- BSSH
- CFTP
- DHTTPS
Show answer & explanationAnswer & explanation
Correct answer: D. HTTPS
HTTPS (Hypertext Transfer Protocol Secure) is the essential protocol for secure communication over a computer network, providing encryption and authentication for web traffic, which is critical for protecting sensitive intranet information.
Why the other options are wrong
- A. SMTP (Simple Mail Transfer Protocol) is for sending email and does not secure web traffic.
- B. SSH (Secure Shell) is for secure remote access to computers, not for securing general web browsing.
- C. FTP (File Transfer Protocol) is for transferring files and is typically unencrypted.
HTTPS (Hypertext Transfer Protocol Secure)
An extension of the Hypertext Transfer Protocol (HTTP) that provides secure communication over a computer network. HTTPS encrypts data using TLS/SSL, ensuring data confidentiality, integrity, and authenticity.
- Encrypts web traffic.
- Uses TLS/SSL for security.
- Indicated by a padlock icon in browsers and 'https://' prefix.
Memory trick: HTTPS: Hypertext Transfer Protocol Secured.
