Fraud Prevention: Internal Controls & Segregation of Duties
Use the ARC framework to close oversight loopholes and stop financial theft before it starts.
Fraud Prevention: Internal Controls & Segregation of Duties

This Fraud Prevention: Internal Controls & Segregation of Duties course walks you through the internal controls that keep one person from having too much power over finances moving through a business. It is built for anyone who wants practical fraud prevention and segregation-of-duties training, not just theory. Many fraud cases start the same way: a single employee handles approval, recordkeeping, and asset custody, with no one checking their work. This course covers why regulations such as Sarbanes-Oxley and the COSO framework exist, and how gaps in IT access controls, such as the one behind the Colonial Pipeline breach, expose entire systems to attack.
You will learn the ARC framework step by step, separating authorization, record keeping, and custody across different roles. The training also covers approval thresholds, three-way matching between purchase orders and invoices, audit trail design, and monitoring tools used in real compliance and audit work. Real fraud cases anchor the training, from a municipal clerk who hid a $53 million theft for over 20 years, to a freight company that redesigned its workflow to close a dangerous overlap in duties.
By the end of this course, you can build fraud-resistant workflows, set sensible approval limits, and spot the internal control weaknesses that auditors look for. It suits compliance officers, internal auditors, finance managers, and operations staff who need hands-on training in fraud prevention and internal controls.
In this course, you will learn how to:
- Construct workflows separating authorization, record keeping, and custody.
- Implement fraud controls to block ghost vendors and invoice slicing.
