Cybersecurity in banking has become a critical concern globally, with Nigerian banks facing unique challenges and implementing distinct strategies to protect their financial systems. The paper reviews cybersecurity practices in banking, focusing on Nigerian banks. Cybersecurity threats, including data breaches, ransomware, and financial fraud, have increased, prompting financial institutions to strengthen their cybersecurity frameworks. Nigeria, as a key player in African banking, has developed specific strategies to address these challenges, including regulatory frameworks, incident response mechanisms, and collaboration with international cybersecurity entities. The study analyzes case studies of real-world cyber threats and incidents in both global and Nigerian banking contexts, examining the effectiveness of cybersecurity measures. It also explores collaborative initiatives between Nigerian banks, regulatory bodies, and international organizations to enhance information sharing, threat intelligence, and collective defense mechanisms. Public awareness campaigns are highlighted as essential for fostering a cyber-resilient banking environment. The study underscores the importance of ongoing adaptation, collaboration, and innovation in safeguarding the integrity and trustworthiness of banking systems, both globally and in Nigeria. The Nigerian banking sector is dynamic, with a growing digital financial landscape and a diverse range of financial institutions. Challenges include economic fluctuations, regulatory compliance, and the need for continuous adaptation to technological advancements. However, these challenges also present opportunities for innovation and resilience. The Nigerian banking sector faces cyber threats such as phishing, ransomware, and mobile banking vulnerabilities. Strategies for cyber resilience include adherence to regulatory standards, investment in advanced cybersecurity technologies, and fostering a cybersecurity-conscious culture. Collaborative efforts between government agencies, law enforcement, and the private sector are crucial in addressing these challenges. The role of cybersecurity in national development is multifaceted, involving the protection of critical infrastructure, safeguarding sensitive data, and fostering economic and societal progress. Government initiatives, such as national cybersecurity strategies and legislative measures, play a vital role in strengthening cybersecurity defenses. The future of cybersecurity in banking will be shaped by advancements in technology, including artificial intelligence, blockchain, and biometric authentication. Continuous adaptation and collaboration are essential to ensure the resilience and security of financial systems in an increasingly interconnected world.Cybersecurity in banking has become a critical concern globally, with Nigerian banks facing unique challenges and implementing distinct strategies to protect their financial systems.
