Management and auditor are concerned about segregation of duties in computer based systems? Why? How to mitigate this concern?
Which of the following would strengthen organizational control over a large-scale data processing center?a. Requiring the user departments to specify the general control standards necessary for processing transactions.b. Requiring that requests and instructions for data processing services be submitted directly to the computer operator in the data center.c. Having the database administrator report to the manager of computer operations.d. Assigning maintenance responsibility to the original system designer who best knows its logic.e. None of the above.
Which statement best describes the issue of distributed data processing (DDP)?a. The centralized and DDP approaches are mutually exclusive; an organization must choose one approach or the other.b. The philosophy and objective of the organization’s management will determine the extent of DDP in the firm.c. In a minimum DDP arrangement, only data input and output are distributed, leaving the tasks of data control, data conversion, database management, and data processing to be cen- trally managed.d. The greatest disadvantage of a totally distributed environment is that the distributed infor- mation processing unit locations are unable to communicate and coordinate their activities.e. Although hardware (such as computers, database storage, and input/output terminals) can be effectively distributed, the systems development and maintenance tasks must remain centralized for better control and efficiency.
