Answer: C
The process of applying a mathematical algorithm to the data
that travels in the network and placing the results of this
operation with the hash data is used for controlling data
integrity, since any unauthorized modification to this data
would result in a be different hash. The application of a
digital signature would accomplish the nonrepudiation of the
delivery of the message. The term security is a broad
concept and not a specific one. In addition to a hash and a
digital signature, confidentiality is applied when an
encryption process exists.

Answer / adja
Just like a traditional manual signature, when a message is digitally signed it applied that the receiver agreed on the integrity of that document. You don't sign a document you disagree to. It is Non-Repudiation because this signature is unique to that person and a proof of the person's identity (Authentication). So the a digitally signed document can provide INTEGRITY, NON-REPUDIATION and AUTHENTICATION. From all the answers only "C" provides the right answer

When conducting a review of business process re-engineering, an IS auditor found that a key preventive control had been removed. In this case, the IS auditor should: A. inform management of the finding and determine if management is willing to accept the potential material risk of not having that preventing control. B. determine if a detective control has replaced the preventive control during the process and if so, not report the removal of the preventive control. C. recommend that this and all control procedures that existed before the process was reengineered be included in the new process. D. develop a continuous audit approach to monitor the effects of the removal of the preventive control.
