Cyber-Secure Cloud Architecture Integrating Network and API Controls for Risk-Aware SAP Healthcare Data Platforms

Abstract

The rapid digitalization of healthcare systems has increased reliance on SAP-based platforms deployed on cloud infrastructures, introducing complex challenges related to cybersecurity, data governance, and operational risk. This paper proposes a cyber-secure cloud architecture that integrates network-level security mechanisms and API governance controls to enable risk-aware management of healthcare data platforms. The architecture combines zero-trust networking, intrusion detection and prevention systems, secure API gateways, and policy-driven data access to protect sensitive clinical and operational data across hybrid and multi-cloud environments. Risk-aware analytics are embedded into the platform to continuously assess security posture, data access behavior, and system performance, supporting informed decision-making and regulatory compliance. The proposed framework aligns with healthcare standards such as HIPAA and GDPR while supporting scalable SAP workloads and real-time data processing. Through architectural analysis and use-case-driven evaluation, the study demonstrates how integrated network and API controls can reduce attack surfaces, improve data integrity, and enhance system resilience. The results indicate that the proposed approach enables secure, compliant, and scalable SAP healthcare data platforms capable of supporting mission-critical healthcare operations.
