Most Recommended Encryption Standard for VPN Connection in AWS

Answer - B.

Note that in the AWS Documentation, when you look at the configuration of a VPN connection, below are the minimum and recommended encryption protocols.

The most recommended encryption standard used for a VPN connection in AWS is AES (Advanced Encryption Standard). AES is a symmetric-key block cipher encryption algorithm that is widely adopted and considered to be highly secure.

The other options, Twofish, Blowfish, and TripleDES, are also symmetric-key encryption algorithms, but they are not as widely used or considered to be as secure as AES.

Twofish and Blowfish are both block ciphers that operate on 128-bit blocks of data and use a variable-length key, while TripleDES is a block cipher that operates on 64-bit blocks of data and uses a key length of 168 bits.

AES, on the other hand, is a block cipher that operates on 128-bit blocks of data and uses a key length of 128, 192, or 256 bits, depending on the level of security required. It has been adopted as a standard by the US government and is widely used in various industries for data encryption.

In summary, AES is the most recommended encryption standard for VPN connections in AWS due to its widespread adoption, high level of security, and flexibility in key length.
