Integrating ZeroTrust Architectures in Healthcare and Financial Sectors: A Cybersecurity Strategy for Enhanced Data Privacy

Abstract

Growth in these digitalenabled applications, and the continued deployment of automation technologies for better efficiency during a time when onpremises labour is more expensive, means we need strong cybersecurity strategies to safeguard patient data as well as sensitive financial information from newer threats. The traditional perimeterbased security models are also proving futile against highly advanced attacks and insider threats. Zero Trust Architectures have been considered as a holistic way to improve data privacy in these sectors, and our work examines how Zero Trust concepts can be introduced. ZTA is based on the idea of 'never trust, always verify', thereby removing implicit trust and applying robust access control for each user, device or application irrespective of its location.The research reviews the fundamental pillars of ZTA such as least privilege access, microsegmentation and continuous authentication alongside evaluate how well they practically fit in with healthcare and finance regulatory environment specifically. We detail the advantages of implementing ZTA, which include a decreased attack surface area, better data breach containment and compliance with regulations around privacy like HIPAA or GDPR.
