✓ :~~ You answered B. The correct answer is D.
A. Digital signatures are used for authentication and nonrepudiation, and are not
commonly used in databases. As a result, this is not an area in which the IS auditor
should investigate.
B. A nonce is defined as a "parameter that changes over time" and is similar to a
number generated to authenticate one specific user session. Nonces are not
related to database security (they are commonly used in encryption schemes).
