CYBER CRIME AND SECURITY AMONG NIGERIAN BANKING SYSTEM

Abstract

The expansion of digital banking has transformed financial service delivery while simultaneously increasing exposure to cyber-related threats within the Nigerian banking system, making bank security a growing concern for regulators, institutions, and customers. This paper examined cybercrime and financial institutions by reviewing bank security in Nigeria with the objective of analysing how cybercriminals gain access to individual and corporate accounts, why cybercrime persists despite regulatory interventions, the socio-economic implications for the banking sector and national image, and the effectiveness of institutional and customer responses to cyber crime. The paper was anchored on Routine Activity Theory, which explains cybercrime as a function of the convergence of motivated offenders, suitable targets, and weak guardianship within routine digital banking activities. Adopting a theoretical and systematic review methodology, the paper relied exclusively on secondary data drawn from peer-reviewed academic studies, regulatory publications, and industry reports relevant to cybercrime and banking operations in Nigeria. The paper showed that cybercrime is facilitated by social engineering techniques, technological gaps, insider collaboration, and uneven digital literacy, while unemployment, inequality, and weak enforcement sustain offender motivation. The paper further revealed that cybercrime imposes financial losses, undermines trust in digital banking, and damages Nigeria’s domestic and international reputation. Although banks and customers have adopted security measures, these responses remain uneven and largely reactive. The paper concluded that strengthening institutional guardianship is central to improving bank security. It therefore recommended enhanced technological controls, stronger regulatory coordination, sustained cybersecurity education, and integrated socio-economic interventions to reduce cybercrime risks in Nigeria’s banking sector.
