Abstract
This work provides a framework for understanding and addressing critical issues at the intersection of financial crimes and security threats. This work contributes to a broader understanding and potential mitigation of challenges faced by African nations, particularly Nigeria. Investigating the nexus between Illicit Financial Flows (IFFs) and terrorism financing (TF), this work argues that it is crucial for global security. Thus, this work assesses the impact of IFFs and TF on Nigeria's economy and security, including the economic, social, and political consequences, and evaluates the effectiveness of Nigeria's current anti-money laundering and counter-terrorism financing measures in preventing IFFs and TF and identifies areas for improvement. To stop the flow of illegal products and money across Nigeria's borders, this work recommends that serious measures, including stepping up border patrols, using cutting-edge monitoring technologies, and improving coordination with the security services of surrounding nations, are crucial.
