Here is the CISA Exam practice question! Today's question is on Electronic Signatures. You can find a post about the basic concepts of digital signatures here. I suggest you read the post and then go ahead answer the question below.

Q). Electronic signatures can prevent messages from being:

a) Erased
b) Disclosed
c) Repudiated
d) Forwarded

Answer: The correct answer is "C" Repudiated. Electronic signatures act as a receipt of a transaction. This ensures that parties who were part of the transaction cannot later on repudiate their commitments. All the other answers are incorrect.
