Establishes an enterprise-grade SAP ABAP integration and interface security framework that enables organizations to design, control, and secure system integrations with precision, discipline, and accountability. Designed for complex landscapes, this policy bridges the gap between enterprise integration security expectations and SAP-specific risks, including uncontrolled interface exposure, insecure service configurations, excessive trust relationships, identity propagation abuse, data leakage, and unauthorized system-to-system access. It defines the governance model, interface inventory and lifecycle requirements, integration design and documentation standards, authentication and authorization controls, data protection requirements, and monitoring expectations necessary to ensure secure interface operation, controlled data exchange, prevention of unauthorized access, and consistent enforcement of security controls across all SAP integrations, interfaces, and supporting infrastructure.
