This paper explores the integration of Artificial Intelligence (AI), Blockchain, and Business Intelligence (BI) to revolutionize banking security and ensure a resilient financial ecosystem. As digital banking and online transactions grow, traditional security measures are increasingly inadequate to combat sophisticated cyber threats. The integration of AI, Blockchain, and BI offers a proactive and adaptive approach to cybersecurity, enabling banks to detect and respond to threats in real-time, secure transactions, and enhance regulatory compliance. AI is used for real-time threat detection by analyzing vast amounts of data to identify patterns and anomalies indicative of suspicious behavior. Blockchain provides a decentralized and immutable ledger that ensures the integrity and transparency of financial transactions, making them tamper-proof and verifiable. BI complements AI and Blockchain by providing actionable insights derived from data analytics, enabling banks to understand their security posture, identify vulnerabilities, and prioritize remediation efforts. The integration of these technologies enhances threat detection, secures transactions, and improves regulatory compliance. AI enables proactive threat detection, Blockchain ensures secure and transparent transactions, and BI provides data-driven insights for informed decision-making. This integrated approach addresses the complexities of modern cyber threats, strengthens cybersecurity defenses, and safeguards customer data. The paper highlights the importance of adopting proactive security measures and leveraging advanced technologies to stay ahead of evolving cyber threats. It emphasizes the need for collaboration, innovation, and adaptability in fortifying cybersecurity within the banking sector. By embracing AI, Blockchain, and BI, banks can enhance their security posture, protect customer assets, and maintain trust in an increasingly digital and interconnected world.This paper explores the integration of Artificial Intelligence (AI), Blockchain, and Business Intelligence (BI) to revolutionize banking security and ensure a resilient financial ecosystem.
