Certified Ethical Hacker (CEH v12) — Question 39

Bella, a security professional working at an IT firm, finds that a security breach has occurred while transferring important files. Sensitive data, employee usernames, and passwords are shared in plaintext, paving the way for hackers to perform successful session hijacking. To address this situation, Bella implemented a protocol that sends data using encryption and digital certificates.
Which of the following protocols is used by Bella?

Answer options

• A. FTPS
• B. FTP
• C. HTTPS
• D. IP

Correct answer: A

Explanation

The correct answer is A, FTPS, which provides secure file transfer by utilizing SSL/TLS encryption. FTP, option B, does not encrypt data, making it unsuitable for secure transfers. HTTPS, option C, is primarily used for secure web traffic rather than file transfers, and IP, option D, is a protocol for routing packets and does not concern data encryption.
