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

The correct answer is A. Advanced Encryption Standard (AES). AES is a symmetric encryption algorithm used to encrypt data at rest. When personal data stored in databases, files, or backups is AES-encrypted, an unauthorized party who gains physical or logical access to the storage medium still cannot read the data without the decryption key

Explanation

AES is a symmetric encryption algorithm used to encrypt data at rest. When personal data stored in databases, files, or backups is AES-encrypted, an unauthorized party who gains physical or logical access to the storage medium still cannot read the data without the decryption key. TLS (B) encrypts data in transit between endpoints-it does not protect stored data. An intrusion detection system (C) monitors for suspicious activity and alerts administrators, but it does not prevent access to the data itself once a breach occurs. Data loss prevention (D) detects and blocks unauthorized data exfiltration, but does not encrypt stored data or prevent an insider with storage access from reading it.
