Exam 9: Controlling Information Systems: Business Process and Application Controls

A(n) ____________________ digit is an extra digit that is added to an identification number to help control the accuracy with which the number is entered into a computer system.

Master data control plans regulate transaction processing by calculating control totals at various points in a processing run and subsequently comparing these totals.

A summation of customer account numbers taken from a batch of sales invoices would be classified as a:

The most error-prone and inefficient steps in an operations or information process is

Immediately endorsing incoming checks satisfies the control goal of

A control whose primary purpose is to ensure greater input accuracy is:

Which batch control total generally has no other purpose than control?

Control ____________________ addresses whether the control goals are being achieved.

We prefer to ____________________________________________________________ to ensure that business event data is entered in a timely manner and that personnel who enter the data can confirm its legitimacy and easily correct errors.

A dependency check employs data encryption--specifically public-key cryptography--to authenticate a system user's identity and to verify the integrity of a message transmitted by that user.

In order to implement either a batch sequence check or cumulative sequence check, transactions must be captured on documents that are randomly numbered.

To reduce the number of keystrokes required, making data entry quicker and more efficient, we can _________________________________________________________________ in response to the entry of identification codes, such as customer numbers, and have the computer retrieve stored data corresponding to those identification codes.

_________________________ are simple counts of the number of documents entered.

Inputting a range of numbers comprising a batch and then inputting each serially numbered document is characteristic of the control plan called:

A control that can be used to ensure that all of the characters of a social security number are entered by a data entry clerk is:

Programmed edit checks are edits automatically performed by data entry programs upon entry of the input data.

A(n) ______________________________ employs data encryption--specifically public-key cryptography--to authenticate a system user's identity and to verify the integrity of a message transmitted by that user.

Written approval takes the form of a signature or initials on a document to indicate that the proper person has authorized the event.

The columns in a control matrix contain headings listing the business process

Not knowing whether input data has been accepted by the information system, the user enters the data again, resulting in duplicate event data.The control plan that helps to prevent this error is:
