➢ Audit procedures in IT environment:

In performing Substantive tests: The auditor can accumulate the needed
electronic evidences and audit trails through CAATs (Computer Assisted Audit
Techniques) which substitute traditional audit procedures, as Follows:

Four of the most commonly used techniques are:

A) Embedded audit modules (EAM):

▪ Are specialized programming modules inserted in the client system to achieve
the purpose of continuous auditing, by capturing the audit related information on
a continuous basis. Require modification to client`s system

▪ It evaluates the transactions against the specifications in real time and sends
reports to the specified individuals.

B) Processing test data:

▪ Test data is used by the auditor to test the existence and effectiveness of controls
built into an application program used by an audit client. As such, dummy
transactions are processed through the client’s computerized system, When the
system is not in use. Require separate testing of the system

▪ It compares the results of processing to the auditor’s expected results to
determine whether controls are operating efficiently, and systems’ objectiveness
are being achieved.

C) Integrated test facility (ITF):

▪ Technique involves the creation of a fictitious entry in the database to process
the test transaction in the system while in use. This fictitious entry is the test
transaction which is run with the normal transactions in the system and can be
implemented periodically without requiring a separate process for testing the
system.

▪ Used when test data is run live to avoid the risk of corrupting a client’s
accounting system.
