Cybersecurity Challenges in Healthcare Information Systems and Strategies for Protecting Sensitive Patient Data in Digital Environments

Abstract

The rapid digitalization of healthcare systems has significantly increased the volume and complexity of sensitive patient data, making cybersecurity a critical concern. Healthcare Information Systems (HIS) are increasingly targeted by cyber threats, including data breaches, ransomware attacks, and unauthorized access. This study evaluates cybersecurity challenges in healthcare environments and explores strategies for protecting sensitive patient data. A convergent mixed-methods approach was employed, combining quantitative data from 185 healthcare and cybersecurity professionals with qualitative insights from case studies and expert interviews. The findings indicate that while digital systems improve healthcare efficiency, they also introduce significant vulnerabilities. Effective cybersecurity strategies, including encryption, access control, and staff training, are essential for mitigating risks. The study provides comprehensive recommendations for strengthening cybersecurity frameworks in healthcare systems.
