When reviewing encryption applied to data within an organization's databases, a cybersecurity analyst notices that some databases use the encryption…

AES-256 (Advanced Encryption Standard) is the recommended algorithm for encrypting data within

databases because:

Strong Encryption: Uses a 256-bit key, providing robust protection against brute-force attacks.

Widely Adopted: Standardized and approved for government and industry use.

Security Advantage: AES-256 is significantly more secure compared to older algorithms like 3-DES or

SHA-1.

Performance: Efficient encryption and decryption, suitable for database encryption.

Incorrect Options:

B . TLS 1.1: Protocol for secure communications, not specifically for data encryption within databases.

C . SHA-1: A hashing algorithm, not suitable for encryption (also considered broken and insecure).

D . DES: An outdated encryption standard with known vulnerabilities.

Exact Extract from CCOA Official Review Manual, 1st Edition:

Refer to Chapter 6, Section "Encryption Standards," Subsection "Recommended Algorithms" - AES-

256 is the preferred algorithm for data encryption due to its security and efficiency.
