Controlling the IT
Environment
Workflow controls:
 Segregation of duties
 Use of information from
prior events to control
activities
 Required sequence of
events
 Follow-up on events
Controlling the IT
Environment
Workflow controls:
 Sequence of
prenumbered documents
 Recording of internal
agent(s) accountable for
an event in a process
 Limitation of access to
assets and information
 Reconciliation of records
with physical evidence of
assets
Controlling the IT
Environment
Input controls:
 Drop-down or look-up
menus
 Record checking of data
entered
 Confirmation of data
entered
 Referential integrity
controls
 Format checks to limit data
 Validation rules to limit the
data
Controlling the IT
Environment
Input controls:
 Defaults from data
entered in prior sessions
 Computer-generated
values entered in records
 Batch control totals taken
before data entry
compared to printouts
after data entry
 Review for errors before
posting
 Exception reports
Controlling the IT
Environment
General controls:
 Information systems (IS)
planning
 Organizing the IT
function
 Identifying and
developing IS solutions
 Implementing and
operating accounting
systems
Controlling the IT
Environment
Performance reviews:
 Establish budgets,
forecasts, standards, or
prior-period results
through file maintenance
 Use reports to compare
actual results to budgets,
forecasts, standards, or
prior-period results
 Take corrective action by
modifying appropriate
reference data in a
master table

General Controls:
Organizing the IT
Function
Locate the IT function
appropriately
Segregate incompatible
functions:
 Separating users from
computer operations
 Separating systems
development and computer
operations
 Separating systems
development and
maintenance
 Separating components of
systems development
