Certified Ethical Hacker (CEH v11) — Question 200

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, as it provides secure file transfer using encryption and digital certificates. Option B, FTP, does not offer any encryption, making it vulnerable to interception. Option C, HTTPS, is used for secure web communication but is not specifically designed for file transfers. Option D, IP, is a network layer protocol and does not provide security features for data transmission.
