The specialised nature of information systems (IS) audit and assurance and the skills necessary to perform such engagements require standards that apply specifically to IS audit and assurance. The development and dissemination of the IS audit and assurance standards are a cornerstone of the ISACA professional contribution to the audit community.
IS audit and assurance standards define mandatory requirements for IS auditing and reporting and inform:
- IS audit and assurance professionals of the minimum level of acceptable performance required to meet the professional responsibilities set out in the ISACA Code of Professional Ethics
- Management and other interested parties of the profession’s expectations concerning the work of practitioners
- Holders of the Certified Information Systems Auditor (CISA) designation of requirements. Failure to comply with these standards may result in an investigation into the CISA holder’s conduct by the ISACA Board of Directors or appropriate committee and, ultimately, in disciplinary action.
IS audit and assurance professionals should include a statement in their work, where appropriate, that the engagement has been conducted in accordance with ISACA IS audit and assurance standards or other applicable professional standards.
The ITAF™ framework for the IS audit and assurance professional provides multiple levels of guidance:
- Standards, divided into three categories:
- General standards (1000 series)—Are the guiding principles under which the IS audit and assurance profession operates. They apply to the conduct of all assignments, and deal with the IS audit and assurance professional’s ethics, independence, objectivity and due care as well as knowledge, competency and skill. The standards statements (in bold) are mandatory.
- Performance standards (1200 series)—Deal with the conduct of the assignment, such as planning and supervision, scoping, risk and materiality, resource mobilisation, supervision and assignment management, audit and assurance evidence, and the exercising of professional judgement and due care
- Reporting standards (1400 series)—Address the types of reports, means of communication and the information communicated
- Guidelines, supporting the standards and also divided into three categories:
- General guidelines (2000 series)
- Performance guidelines (2200 series)
- Reporting guidelines (2400 series)
- Tools and techniques, providing additional guidance for IS audit and assurance professionals, e.g., white papers, IS audit/assurance programmes, the COBIT 5 family of products
An online glossary of terms used in ITAF is provided at www.isaca.org/glossary.

IS audit and assurance professionals shall monitor relevant information to conclude whether management has planned/taken appropriate, timely action to address reported audit findings and recommendations.
The internal IS audit function should establish a follow-up process to monitor and ensure that management actions have been effectively implemented or that senior management has accepted the risk of not taking action.
External IS audit or assurance professionals may rely on an internal IS audit function to follow up on their agreed-upon recommendations, depending on the scope and terms of the engagement.
