Answer: B
Utility software in this case is a data correction program
for correcting any inconsistency in data. However, this
utility can be used to over-ride wrong update of tables
directly. Hence, access to this utility should be restricted
on a need-to-use basis and a log should be automatically
generated whenever this utility is executed. The senior
management should review this log periodically. Deleting the
utility and installing it as and when required may not be
practically feasible as there would be time delay. Access to
utilities should not be provided to user management.
Defining access so that the utility can be executed in a
menu option may not generate a log.
