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 that should be present (as well as designed and operating effectively) in order to prevent future frauds. These controls are taken from Association of Certified Fraud Examiners’ Report to the Nations: 2020 Global Study on Occupational Fraud and Abuse. 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 internal controls in the coming era.
