What is the encryption method used for storage encryption?

• A. RSA 2048 PKI
• B. AES 256
• C. 3DES
• D. Twofish

Answer: (A)

The encryption method used for storage encryption is AES 256. Advanced Encryption Standard (AES) is a symmetric encryption algorithm known for its strength and efficiency, particularly suited for securing sensitive data stored on disk, ensuring that the data remains confidential and protected against unauthorized access.

AES 256 specifically uses a key length of 256 bits, which is currently one of the strongest encryption standards available and is widely recognized and adopted across various industries for data protection. Its robustness makes it suitable for compliance with regulations and standards that mandate high levels of data security.

RSA with a key length of 2048 bits is an asymmetric encryption algorithm primarily used for secure data transmission rather than storage. It does not provide the same level of efficiency or performance when it comes to encrypting large volumes of stored data.

3DES, or Triple DES, is an older symmetric-key encryption algorithm that applies DES encryption three times to each data block. While it was an improvement over its predecessor, it is now considered less secure and slower compared to AES, which provides a more modern and efficient approach to data encryption.

Twofish is another symmetric key block cipher like AES, but it is not as widely adopted as AES for standard encryption practices. AES has become the default choice for numerous applications and regulations due
