Security Architecture
Security Architecture for SAP landscapes covering identity and access design, authentication and authorization models, network and data protection, and governance across ECC, S/4HANA (on-premise, private cloud, public cloud) and BTP/cloud extensions, with emphasis on clean core principles, hybrid integration security and lifecycle operations.
Overview
Security Architecture for SAP landscapes covering identity and access design, authentication and authorization models, network and data protection, and governance across ECC, S/4HANA (on-premise, private cloud, public cloud) and BTP/cloud extensions, with emphasis on clean core principles, hybrid integration security and lifecycle operations.
Lessons in this topic
- SAP Security Architecture Tutorial (Part 1)Introduces the business and technical purpose of a deliberate security architecture across SAP systems, explaining what problems it solves and why architects must own it end to end.
- Designing Authentication, Authorization and Identity Federation Across the Landscape (Part 2)Explains how to design authentication, authorization and identity federation decisions across ECC, S/4HANA and BTP, including the trade-offs between centralized identity providers, role design strategies and cross-system trust.
- Identity and Authentication Architecture Across Hybrid SAP Landscapes (Part 3)Design a coherent identity and authentication architecture spanning ECC, S/4HANA, and BTP using centralized identity providers, SSO protocols, and provisioning services.
- Governing Security Architecture Across Hybrid ECC, S/4HANA and BTP Landscapes (Part 4)Establishes an architect-level framework for governing security consistently across hybrid ECC/S/4HANA/BTP landscapes, including migration, rollback, cost and operational trade-offs.
- Designing Authorization Concepts and Segregation of Duties for Hybrid Clean-Core Landscapes (Part 5)Architect a scalable authorization concept and segregation of duties framework spanning ABAP roles, S/4HANA business catalogs, and BTP scopes while preserving clean-core principles.
Interview questions covered
- What are the core concepts of Security Architecture, and how would you explain them clearly in an SAP interview?
- How would you apply Security Architecture in a real SAP project? Walk through the design or implementation approach.
- A production issue is reported in Security Architecture. What would you check first, and how would you troubleshoot it systematically?
- What are the most important design decisions, trade-offs, and best practices in Security Architecture?
- Suppose you inherit an existing Security Architecture solution. How would you review it before making a change?
- Using this SAP project situation — During an S/4HANA transformation program, the security architect was asked to approve the target design in week two of blueprinting, before any BTP services or integration patterns had been finalized — explain Why Security Architecture Matters in SAP Landscapes. What should happen, which concepts or process steps matter, and what common mistake would you avoid?
- A project encounters this situation while working on Designing Authentication, Authorization and Identity Federation Across the Landscape: A retail company connected its S/4HANA private cloud system to a BTP-based returns management extension using principal propagation so that store associates' identities carried through to backend postings. Walk through how you would analyze the requirement or issue, what you would validate, and how you would test the solution before release.
- A project encounters this situation while working on Identity and Authentication Architecture Across Hybrid SAP Landscapes: During a phased S/4HANA transition, a client kept ECC live for finance while rolling out S/4HANA private cloud for logistics and BTP-based extension apps. Walk through how you would analyze the requirement or issue, what you would validate, and how you would test the solution before release.
- You are the senior consultant/architect responsible for Designing Authorization Concepts and Segregation of Duties for Hybrid Clean-Core Landscapes. The project situation is: An architecture team building a custom BTP invoice-exception app discovered during a security review that the app's service consumed an OData API allowing invoice status changes, which combined with an existing S/4HANA approver role created an unreviewed SoD conflict for a subset of users who had both accesses. How would you assess the design, identify the highest-risk failure modes, and define the evidence required before approving it for production?
- Using this SAP project situation — During an ECC to S/4HANA private cloud transformation with a new BTP-based approval extension, the architecture board discovered that a manager could both raise and approve high-value purchase requisitions because the SoD tool only scanned ECC/S/4HANA roles and had no visibility into the BTP extension's role collections — explain Governing Security Architecture Across Hybrid ECC, S/4HANA and BTP Landscapes. What should happen, which concepts or process steps matter, and what common mistake would you avoid?
