Cyber security in the FinTech Sector: Securing Digital Transactions

Abstract

The FinTech industry has been growing at a tremendous pace, showing several outbursts of technological innovation, and is further reforming the financial world, equipping it with prolific digital financial services. However, their very nature exhumed a due share of cyber threats. This section discusses the overriding importance of cybersecurity in the FinTech industry, specifically pointing out the security of digital transactions. It outlines various types of cyber threats, including phishing, malware, ransomware, DDoS attacks, and insider threats, against FinTech companies, elaborating on their probable impacts: financial loss, loss of reputation, regulatory penalties, and disruption to operations. The following threats require a multi-layer cybersecurity approach by FinTech companies, which must be backed by data encryption, 2FA, behavioural biometrics, secure APIs, and threat detection with AI. Further, the chapter proceeds with explaining the regulatory frameworks that supervise cybersecurity in the financial industry, such as the GDPR, PCI DSS, and FINRA, with much attention being aroused for compliance assurance. The chapter also provides best practices to ensure cybersecurity: zero-trust architecture, a comprehensive incident response plan, periodic audits, and inculcation of cybersecurity awareness amongst employees. Several real-world case studies involving large cybersecurity breaches in the FinTech sector will help provide insight into poor security practices and the need for eternal vigilance.
