Course Description

Assessing the reliability of computer generated data is an important step in audit planning as well as addressing specific audit objectives. Data is aggregated from various sources, processed using automated rule sets, and stored in databases, data warehouses, etc. Applications and business users extract or retrieve data as the basis for strategic decisions, reporting, day-to-day operations, and auditing. The reliability of data may be at significant risk when placed in operational and IT environments lacking processing, transmission, storage or security controls. Misinterpretation of reliability risk factors may result in misdirected audit effort or incorrect conclusions. This training session will provide you with the concepts and tools to effectively evaluate the reliability of data processed and available for analysis and decision making.

We will focus on:

• How reliability assessment of data from IT systems should be conducted during audit planning when developing audit objectives and audit procedures.

• Key factors to be reviewed during audit planning to assist the auditor in evaluating the sufficiency, reliability and relevance of data to be used as audit evidence.

• Steps to perform when obtaining evidence during the audit regarding data accuracy, completeness and validity.

• Data reliability issues relating to organization, appropriateness of controls, risk, and testing.
