Security Architecture and Zero-Trust Models for SAP BTP (Business Technology Platform)

The acceleration of cloud transformation has brought SAP Business Technology Platform (SAP BTP) to the center of intelligent enterprise architectures. As organizations expand hybrid landscapes integrating SAP S/4HANA, cloud extensions, APIs, and third-party systems, traditional perimeter-based security models have become insufficient [3]. This paper presents comprehensive security architecture grounded in Zero-Trust principles, continuous verification, identity centric security, least privilege design, and micro segmentation, aligned with industry standards defined by NIST and adapted for SAP BTP’s multi-tenant environment. The study evaluates identity governance using SAP Cloud Identity Services, secure integration patterns for SAP CPI, and AI-driven threat detection mechanisms. Through comparative assessments and real-world architectural patterns, this work demonstrates that Zero-Trust adoption significantly enhances confidentiality, integrity, audit readiness, and resilience across SAP BTP ecosystems [5], [10].
