Fraud is a big problem in the public sector, where some people create a monopoly over public resources. To fight this, organizations need to make an anti-fraud strategy. This strategy is all about being honest and not tolerating fraud. Fraud includes things like corruption and lying about money. Fraudsters can be inside or outside the organization. They do fraud because they feel pressure, see an opportunity, or can justify it. The costs of fraud can be hard to figure out. To stop fraud, we need strong laws, a culture that says no to fraud, and a good anti-fraud plan.
