Question
A utility is available to update critical tables in case of data inconsistency. This utility can be executed at the OS prompt or as one of menu options in an application. The BEST control to mitigate the risk of unauthorized manipulation of data is to:

A. delete the utility software and install it as and when required.
B. provide access to utility on a need-to-use basis.
C. provide access to utility to user management
D. define access so that the utility can be only executed in menu option.
Answers
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.   Your Comment
