Introduction
Banks have become prime targets for cybercriminals in an era where digital transactions dominate financial ecosystems. With billions of dollars flowing through online channels and mobile banking apps every day, even a minor security lapse can compromise millions of customer records and cause irreparable damage to trust and reputation.
The increasing adoption of fintech, open banking APIs, and real-time settlements have expanded the attack surface. Cybercriminals now exploit everything from phishing and DDoS attacks to AI-powered fraud and insider threats. Traditional perimeter-based security measures are no longer sufficient to defend the complex, interconnected systems modern banks operate.
Cybersecurity in banking is not just an IT function; it’s a critical component of business resilience, regulatory compliance, and customer trust. For IT leaders and executives, this means implementing proactive, multilayered, and adaptable security strategies. This article dives deep into the threats financial institutions face, the best practices banks should adopt, and how managed IT services providers like Infodot can help build a resilient cybersecurity framework.
