Which of the following would an IS auditor use to determine if unauthorized modifications were made to
production programs?

A.
System log analysis

B.
Compliance testing

C.
Forensic analysis

D.
Analytical review

Explanation:
Determining that only authorized modifications are made to production programs would require the change
management process be reviewed to evaluate the existence of a trail of documentary evidence. Compliance
testing would help to verify that the change management process has been applied consistently. It is unlikely
that the system log analysis would provide information about the modification of programs. Forensic analysis is
a specialized technique for criminal investigation. An analytical review assesses the general control
environment of an organization.
