During a review of a customer master file an IS auditor
discovered numerous customer name duplications arising from
variations in customer first names. To determine the extent
of the duplication the IS auditor would use:
A. test data to validate data input.
B. test data to determine system sort capabilities.
C. generalized audit software to search for address field
duplications.
D. generalized audit software to search for account field
duplications.
Answer / guest
Answer: C
Since the name is not the same (due to name variations), one
method to detect duplications would be to compare other
common fields, such as addresses. Subsequent review to
determine common customer names at these addresses could
then be conducted. Searching for duplicate account numbers
would not likely find duplications since customers would
most likely have different account numbers for each
variation. Test data would not be useful to detect the
extent of any data characteristic, but simply to determine
how the data were processed.
