FHIR (Fast Healthcare Interoperability Resources) is a widely adopted data standard in healthcare that facilitates the exchange of health information, but the integration of SMART on FHIR, Kong Gateway, and Okta enhances the security, scalability, and usability of digital health platforms. SMART on FHIR extends FHIR by incorporating open standards like OAuth 2.0 and OpenID Connect to secure access to electronic health records, while Kong Gateway acts as a control point that validates access tokens and enforces security policies. Okta serves as the identity and access management authority, handling user authentication and token issuance. Together, these technologies create a robust, centralized security framework that ensures healthcare organizations can connect systems confidently, manage identities responsibly, and share data securely in compliance with regulations like HIPAA. Kong's plugins further enhance FHIR services by offering features like rate limiting, caching, and full observability, ensuring high availability and detailed audit trails. This combination supports a modern, interoperable health data platform that can adapt to changes in standards and regulations, positioning healthcare providers to improve outcomes while maintaining strict data privacy.
