Certified Ethical Hacker (CEH) — Question 67

Which of the following is the BEST way to protect Personally Identifiable Information (PII) from being exploited due to vulnerabilities of varying web applications?

Answer options

• A. Use cryptographic storage to store all PII
• B. Use full disk encryption on all hard drives to protect PII
• C. Use encrypted communications protocols to transmit PII
• D. Use a security token to log into all Web applications that use PII

Correct answer: C

Explanation

The correct answer is C because using encrypted communications protocols ensures that PII is securely transmitted over networks, protecting it from interception. While options A and B provide storage protection, they do not address the risk during data transmission. Option D, although useful for authentication, does not directly safeguard the data itself during transmission.
