Answer: C
While it would be preferred that strict separation of duties
be adhered to and that additional staff is recruited, as
suggested in choice B, this practice is not always possible
in small organizations. The IS auditor must look at
recommended alternative processes. Of the choices, C is the
only practical one that has an impact. The IS auditor should
recommend processes that detect changes to production source
and object code, such as code comparisons, so the changes
can be reviewed by a third party on a regular basis. This
would be a compensating control process. Choice A, involving
logging of changes to development libraries, would not
detect changes to production libraries. Choice D is in
effect requiring a third party to do the changes, which may
not be practical in a small organization.
