Exam CISSP-ISSAP topic 2 question 117 discussion

The techniques used by an administrator while working with symmetric encryption cryptography are: A. Block cipher B. Stream cipher Explanation: A. Block cipher: Symmetric encryption algorithms that operate on fixed-size blocks of data, encrypting and decrypting the entire block at a time. B. Stream cipher: Symmetric encryption algorithms that encrypt and decrypt data one bit or byte at a time, typically used for streaming data. C. Transposition cipher: Transposition ciphers are a type of classical cipher and not specific to symmetric encryption cryptography. D. Message Authentication Code (MAC): MAC is a technique for ensuring the integrity and authenticity of a message and is not directly related to symmetric encryption.
