An IT Auditor Has Recently Discovered That Because of a Shortage

An IT auditor has recently discovered that because of a shortage of skilled operations personnel, the security administrator has agreed to work one late night shift a week as the senior computer operator. The most appropriate course of action for the IT auditor is to:

A) Review the system log for each of the late night shifts to determine whether any irregular actions occurred.
B) Inform senior management of the risk involved.
C) Develop a computer-assisted audit technique to detect instances of abuses of the arrangement.
D) Agree to work with the security officer on these shifts as a form of preventative control.
