Establishes an enterprise-grade SAP communication and network security framework that enables organizations to design, control, and secure communication pathways with precision, visibility, and discipline across SAP environments. Designed for complex landscapes, this policy bridges the gap between enterprise network security expectations and SAP-specific risks, including uncontrolled service exposure, misconfigured communication components, insecure protocols, weak segmentation, and unauthorized external access through tightly integrated systems. It defines the governance model, communication architecture requirements, service exposure controls, secure protocol enforcement, component-specific security standards, monitoring and logging expectations, and support connectivity controls necessary to ensure secure system interaction, protection of trust boundaries, and continuous visibility into communication activity across all SAP systems, integrations, and supporting infrastructure.
