CFE Fraud Prevention and Deterrence: Building Controls That Work

Fraud Prevention and Deterrence is one of the three current sections of the Certified Fraud Examiner exam introduced with ACFE’s redesigned CFE structure on June 2, 2026. It is the shortest of the three sections at 70 questions in 1.5 hours, but its scope is broad: candidates are expected to understand why fraud occurs, how organizations create conditions that either discourage or enable misconduct, how fraud risks are assessed, and how governance, management, auditors, controls, culture, and ethics work together.

The section belongs within the wider ACFE fraud-examination body of knowledge. The other current exam sections are Fraud Schemes and Financial Crimes, which concentrates on how schemes operate, and Fraud Investigations and Legal Issues, which focuses on gathering evidence and conducting defensible examinations. Prevention connects those areas by asking what an organization should do before suspicious activity becomes an investigation.

Understanding Why Fraud Happens

Prevention begins with the recognition that fraud is not explained by one personality type or one control failure. Individuals can face financial or personal pressures, perceive an opportunity created by weak oversight, and rationalize behavior that would otherwise conflict with their self-image. Other models add capability, entitlement, organizational culture, group dynamics, or environmental factors. The exam value of these theories is not in memorizing labels in isolation; it is in understanding how different conditions can increase or reduce the likelihood of misconduct.

Opportunity is the factor organizations can influence most directly. Poor segregation of duties, excessive system access, weak review, informal approval practices, absent reconciliations, and management override can create openings that a motivated person can exploit. Yet an organization with technically strong controls can still be vulnerable if employees believe senior leaders ignore policy, retaliation is tolerated, or targets are so unrealistic that manipulation becomes normalized.

Red flags therefore require judgment. A sudden lifestyle change, reluctance to take leave, unusual vendor relationships, missing documentation, repeated overrides, or unexplained accounting adjustments can justify attention, but none proves fraud by itself. Good prevention programs combine behavioral awareness with transaction controls, reporting mechanisms, management review, and disciplined investigation of anomalies.

The practical distinction is important: a red flag is a reason to ask better questions, not a substitute for evidence. Prevention fails when suspicion becomes accusation or when warning signs are dismissed because no single indicator is conclusive.

Governance Sets the Tone and the Boundaries

Corporate governance establishes who is accountable for oversight, how authority is distributed, and how significant risks are challenged. Boards and audit committees are not expected to perform every control, but they should understand the organization’s fraud exposure, receive meaningful information, question unusual trends, and ensure management does not control the entire assurance process.

Independence matters because fraud can originate at any level. If senior executives can override controls, select what information reaches the board, or pressure assurance functions, a control environment can look mature on paper while remaining weak in practice. Governance structures should therefore create channels through which internal audit, compliance, legal, security, finance, and employees can raise material concerns without relying exclusively on the managers whose conduct might be questioned.

Oversight also includes incentive design. Compensation plans, sales quotas, bonus thresholds, earnings expectations, procurement targets, and operational metrics can unintentionally reward behavior that increases fraud risk. A mature organization asks not only whether goals are ambitious but also what behavior those goals encourage when employees are under pressure.

Minutes, policies, delegated authorities, committee charters, escalation rules, and documented review can provide evidence that governance actually operates. That is why principles of control documentation and audit evidence are relevant to prevention: a control that cannot be demonstrated, traced, or reviewed may be much weaker than its policy description suggests.

Management and Auditors Have Different Responsibilities

Management owns the organization’s operating controls and is responsible for establishing processes that reasonably prevent and detect fraud. That includes assigning responsibilities, approving transactions, protecting assets, restricting access, reconciling records, reviewing exceptions, responding to allegations, and correcting known weaknesses. Management cannot transfer this responsibility to internal or external auditors.

Internal audit evaluates whether governance, risk management, and controls are designed and operating effectively. Its perspective can expose gaps between formal policy and actual behavior, especially when testing samples, examining exceptions, or following repeated control failures across business units. Internal audit can also assess whether remediation was completed rather than merely promised.

External auditors have responsibilities defined by professional standards and the engagement they perform. Their work can identify material misstatement risk and control weaknesses, but a financial statement audit is not a guarantee that every fraud will be discovered. Candidates should resist the simplistic idea that “the auditors are responsible for preventing fraud.” Prevention is an organizational responsibility supported by multiple lines of oversight.

Management override deserves special attention because senior personnel can sometimes bypass controls that work well for ordinary employees. Journal entries, estimates, related-party arrangements, unusual contracts, manual payments, and exceptional access can all require additional scrutiny when normal approval chains are overridden.

Fraud Risk Assessment Turns Concern Into Priorities

A fraud risk assessment identifies how fraud could occur in the organization, who could perpetrate it, what assets or processes are exposed, which controls address the risk, and where residual vulnerability remains. The process should be specific enough to reflect the organization’s industry, products, locations, transaction channels, technology, incentives, and regulatory environment.

Useful assessments consider both likelihood and impact but avoid reducing judgment to a single score. A low-frequency scheme can still demand strong controls if the potential financial, legal, safety, or reputational consequences are severe. Likewise, a common low-value abuse can become material when repeated across a large population.

Risk scenarios should be concrete. “Procurement fraud” is too broad by itself. More useful scenarios include a buyer directing contracts to a related vendor, employees splitting purchases to evade approval thresholds, vendors billing for undelivered services, or confidential bid information being shared with a favored supplier. Specific scenarios make it easier to identify preventive controls, detective controls, data sources, owners, and response procedures.

The assessment must also evolve. New payment methods, acquisitions, remote work, third-party relationships, organizational restructuring, economic pressure, and changes in technology can alter fraud exposure. A risk register that is never refreshed can become a historical document rather than a management tool.

Controls Work Best as a Layered System

No single control prevents every scheme. Effective fraud risk management combines preventive, detective, and responsive measures. Preventive controls aim to stop improper activity before it occurs; detective controls identify suspicious events that passed prevention; responsive controls define how the organization investigates, contains, reports, recovers, and improves after an issue is found.

Segregation of duties is a classic preventive principle because it makes it harder for one person to authorize, execute, record, and conceal the same transaction. Where staffing makes perfect segregation impossible, compensating controls such as independent review, exception reporting, or owner oversight can reduce risk.

Access controls should follow job responsibilities and change when roles change. Dormant accounts, excessive privileges, shared credentials, emergency access, and poorly governed administrator rights can undermine otherwise sound workflows. Transaction limits, dual approval, vendor validation, reconciliations, master-data review, inventory counts, and analytical monitoring provide additional layers.

Detective controls should generate signals that someone actually reviews. An exception report that accumulates unread alerts is not a functioning control. Organizations need clear ownership, thresholds, investigation procedures, escalation criteria, and evidence that anomalies were resolved.

Hotlines, Reporting Channels, and Anti-Retaliation Matter

Employees, customers, suppliers, and other insiders often see warning signs before formal controls do. Reporting mechanisms therefore play a central role in prevention and early detection. Channels can include hotlines, web portals, managers, compliance functions, ombuds services, or other routes appropriate to the organization.

A reporting channel is useful only if people trust it. Confidentiality, anonymity where permitted, anti-retaliation protections, consistent triage, timely follow-up, and fair treatment influence whether employees raise concerns. If prior reporters were ignored or punished, a technically sophisticated hotline will not compensate for the cultural failure.

Triage should distinguish urgent threats, potential criminal conduct, conflicts of interest, HR issues, policy violations, control complaints, and matters that lack enough information for immediate action. Consistent intake and documentation help the organization identify repeated allegations or patterns across locations.

Communication after an investigation also matters. Organizations cannot disclose every detail, but demonstrating that concerns are taken seriously reinforces the credibility of the system. Silence after repeated reports can create the impression that nothing happens.

Culture, Ethics, and Incentives Shape Everyday Decisions

Codes of conduct and ethics policies matter, but employee behavior is influenced more strongly by what leaders reward, tolerate, and model. A company can publish a strict anti-fraud statement while simultaneously encouraging employees to “make the numbers work” regardless of how targets are achieved. Candidates should be able to identify the gap between formal values and operational signals.

Training should explain realistic decisions employees face: gifts from suppliers, conflicts of interest, pressure to alter records, use of confidential information, expense claims, approval shortcuts, and reporting duties. Generic annual slides have limited value if they never connect policy to actual work.

Discipline should be consistent enough that status does not create immunity. Unequal treatment can damage deterrence because employees quickly learn whether rules are truly enforced. At the same time, organizations need proportionate, fact-based processes rather than automatic punishment based on accusation alone.

Ethics also govern the fraud examiner. Objectivity, competence, confidentiality, lawful conduct, careful reporting, and avoidance of unsupported conclusions protect both the investigation and the people affected by it. Prevention is weakened when the function responsible for integrity does not model the same standards.

From Prevention Failure to Investigation and Improvement

Even strong programs cannot eliminate fraud risk. When an allegation or anomaly becomes significant, the organization moves from prevention into investigation. The transition should be controlled: preserve records, define authority, avoid unnecessary disclosure, identify conflicts, and decide whether legal, regulatory, law-enforcement, HR, security, or specialist support is needed.

The current CFE structure deliberately connects these disciplines. Knowledge of schemes helps an examiner imagine how misconduct could be executed; prevention knowledge helps identify expected controls and weaknesses; investigation knowledge helps determine whether suspicious facts can be substantiated. Treating the three sections as isolated study silos misses that practical relationship.

After a case, remediation should address root causes rather than only the individual perpetrator. If a fraud succeeded because approvals were superficial, master data was uncontrolled, incentives encouraged manipulation, or hotline reports were ignored, replacing one employee does not fix the system. Lessons learned can lead to redesigned controls, better analytics, revised training, clearer accountability, or governance changes.

Preparation for this section is strongest when candidates practice connecting a fraud scenario to the environment that allowed it. Ask what pressure or incentive existed, what opportunity was available, which controls should have prevented or detected the activity, who owned those controls, what warning signs appeared, and how the organization should respond. That reasoning is more durable than memorizing isolated definitions.
