Answer: D
Reconciliation is a responsibility performed by the data
control group, with the use of control totals and balancing
sheets. This type of independent verification increases the
level of confidence that the application has run
successfully and the data are in proper balance. Access to
data are controls provided by a combination of physical and
logical security in both the user area and the information
processing facility. Authorization tables are built by the
IS department, based on the authorization forms provided by
the data owners. Custody of assets must be determined and
assigned appropriately. The data ownership usually is
assigned to a particular user department, and duties should
be specific and written. The owner of the data has
responsibility for determining authorization levels required
to provide adequate security, while the data security
administration group is often responsible for implementing
and enforcing the security system.
