Companies that fall victim to fraud schemes need to reassess internal controls in order to prevent future fraudulent activity. In this course, we will review the 18 most prevalent internal controls present as well as designed and operating effectively according to the Association of Certified Fraud Examiners’ Occupational Fraud 2022: A Report to the Nations. Then we will tie these controls to the 17 internal control principles offered by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), the framework used by virtually all entities and auditors to assess the design and operational effectiveness of internal controls. Lastly, we will consider the impact of the 2020 pandemic on the internal control environment in the post-COVID pandemic era.
