Certified Data Privacy Solutions Engineer (CDPSE) — Question 160

Which of the following BEST protects against unauthorized access to stored personal data?

Answer options

• A. Advanced Encryption Standard (AES)
• B. Transport Layer Security (TLS)
• C. Intrusion detection system (IDS)
• D. Data loss prevention (DLP)

Correct answer: A

Explanation

The Advanced Encryption Standard (AES) is widely recognized for its ability to securely encrypt data, making it the best choice for protecting stored personal information from unauthorized access. In contrast, Transport Layer Security (TLS) is primarily used for securing data in transit, while Intrusion Detection Systems (IDS) monitor for unauthorized access but do not prevent it. Data Loss Prevention (DLP) focuses more on preventing data leaks rather than specifically protecting data from unauthorized access.
