Internal control and IT on CPA AUD

AUD tests the auditor's understanding of internal control and IT: the COSO components, control activities including segregation of duties, IT general and application controls, tests of controls and the evaluation of deficiencies.

What to know

  • COSO 2013 has five components: control environment, risk assessment, control activities, information and communication, and monitoring activities.
  • Authorization, recordkeeping and custody of the same assets should be separated.
  • IT general controls cover access, program changes and operations; application controls (edit, limit, field and sequence checks, batch totals) operate within applications.
  • Controls are tested when the auditor plans to rely on them or when substantive procedures alone cannot provide sufficient appropriate evidence (AU-C 330.08).
  • A material weakness is a deficiency with a reasonable possibility that a material misstatement will not be prevented, or detected and corrected, on a timely basis (AU-C 265.07).
  • Integrated audits under PCAOB AS 2201 use a top-down approach, starting with the financial statements and entity-level controls.
