In an increasingly digital world, businesses are adopting a hybrid IT landscape, combining the stability of on-premise systems with the agility and scalability of cloud solutions. While this approach offers significant advantages, it also introduces new complexities, particularly in the realm of governance, risk, and compliance (GRC). Implementing SAP GRC in such hybrid environments requires a strategic approach to ensure consistent security, seamless access management, and robust compliance across both on-premise and cloud systems.
¶ Implementing SAP GRC for Hybrid Environments: Bridging the On-Premise and Cloud Divide
The shift to hybrid IT landscapes, driven by factors like cloud adoption for specific applications (e.g., SAP Ariba, SuccessFactors, Concur), strategic S/4HANA migrations, and evolving business needs, presents a unique set of challenges for GRC teams. Organizations must now manage user access, enforce Segregation of Duties (SoD), and maintain audit trails across a diverse ecosystem that includes both traditional SAP ECC or S/4HANA on-premise instances and various cloud-based applications.
The Hybrid Landscape Challenge for GRC
Operating in a hybrid environment complicates GRC in several ways:
- Disparate Systems and Data Silos: Information about user access, roles, and business processes can be scattered across multiple on-premise and cloud systems, making it difficult to gain a holistic view of risks.
- Inconsistent Security Policies: Applying uniform security policies and access controls across different platforms, each with its own security mechanisms, can be a major hurdle.
- Complex Integration Requirements: Connecting on-premise GRC solutions with cloud applications for automated provisioning, risk analysis, and audit logging often requires intricate integration efforts.
- Evolving Compliance Mandates: Regulations like GDPR, SOX, and industry-specific compliance requirements must be met consistently across all parts of the hybrid landscape, demanding comprehensive visibility and control.
- User Experience and Productivity: Users require seamless access to applications, regardless of whether they reside on-premise or in the cloud, without compromising security or efficiency.
- Role Management Complexity: Defining and maintaining consistent business roles that span both on-premise and cloud applications becomes more challenging.
SAP's Approach to GRC in Hybrid Environments
SAP offers a powerful combination of solutions to address the complexities of GRC in hybrid environments:
-
SAP GRC Access Control (On-Premise): This remains the cornerstone for managing GRC for traditional SAP landscapes. Its robust capabilities for Access Risk Analysis (ARA), Access Request Management (ARM), Business Role Management (BRM), and Emergency Access Management (EAM) are essential for governing on-premise SAP systems.
-
SAP Cloud Identity Access Governance (IAG): This is SAP's cloud-native solution designed specifically for identity and access governance in hybrid and cloud-centric environments. IAG offers a streamlined approach to:
- Access Requests and Provisioning: Self-service capabilities for requesting access to cloud and on-premise systems, with automated provisioning.
- Access Risk Analysis: Real-time SoD analysis for both cloud and connected on-premise systems.
- Role Design: Tools to define and manage roles that can span across hybrid landscapes.
- Access Certification: Facilitating periodic user access reviews for compliance.
- Privileged Access Management: Securely managing elevated access in cloud applications.
The "IAG Bridge" Scenario: The Hybrid Harmony
The most common and recommended approach for existing SAP GRC Access Control customers in a hybrid environment is the IAG Bridge scenario. This leverages your existing investment in SAP GRC Access Control (on-premise) while extending its capabilities to govern cloud applications through SAP IAG.
Here's how the IAG Bridge works:
- Centralized GRC Control: SAP GRC Access Control (on-premise) acts as the central hub for access governance. Access requests for both on-premise and cloud systems are initiated and managed within GRC AC.
- IAG as the Cloud Gateway: SAP IAG serves as the bridge, connecting GRC AC to various SAP cloud applications (e.g., SuccessFactors, Ariba, Concur, S/4HANA Cloud) and even some non-SAP cloud solutions.
- Cross-System Risk Analysis: When an access request involves both on-premise and cloud components, GRC AC can utilize IAG's capabilities to perform cross-system SoD analysis, identifying potential conflicts that span across your hybrid landscape. This provides a holistic view of access risks.
- Automated Provisioning: Upon approval in GRC AC, the provisioning requests are sent to IAG, which then handles the automated provisioning of access in the target cloud applications. Similarly, GRC AC handles provisioning for on-premise systems.
- Unified Reporting and Audit Trail: All access requests, approvals, provisioning actions, and risk analyses are logged and auditable from a central point, providing a complete compliance record for both environments.
Benefits of Implementing SAP GRC in a Hybrid Environment
- Holistic Risk Management: Gain a comprehensive view of access risks across your entire IT landscape, encompassing both on-premise and cloud systems.
- Consistent Compliance: Enforce uniform security policies and compliance mandates across diverse platforms, simplifying audits and reducing compliance breaches.
- Streamlined Access Lifecycle: Automate user provisioning and de-provisioning across hybrid systems, reducing manual effort and improving efficiency.
- Enhanced Security Posture: Proactively identify and mitigate SoD conflicts, sensitive access violations, and privileged access risks in real-time, regardless of where the system resides.
- Improved User Experience: Provide a consistent and efficient access request experience for users, regardless of the target application's deployment model.
- Leverage Existing Investments: The IAG Bridge scenario allows organizations to protect their existing investment in SAP GRC Access Control while extending its reach to the cloud.
Key Considerations for Implementation
- Integration Planning: Meticulously plan the integration points between SAP GRC Access Control, SAP IAG, and all target on-premise and cloud systems. This includes connectivity, data synchronization, and workflow orchestration.
- Unified Role Design: Develop a strategy for designing and managing business roles that effectively span both on-premise and cloud applications, minimizing redundant roles and ensuring proper access.
- SoD Rule Set Extension: Review and extend your existing SoD rule set to account for potential conflicts arising from cross-system access across your hybrid environment.
- Identity Management Strategy: Consider integrating with a central identity provider (e.g., SAP Cloud Identity Services, or other enterprise identity management solutions) to ensure consistent user identities across all systems.
- Continuous Monitoring and Reporting: Establish robust monitoring processes and reporting capabilities to gain real-time insights into access risks and compliance status across your hybrid landscape.
- Skills and Training: Ensure your GRC team possesses the necessary skills to manage both on-premise GRC and cloud-based IAG solutions.
Conclusion
The move to hybrid environments is a strategic imperative for many organizations. While it introduces complexities for GRC, SAP GRC Access Control in conjunction with SAP Cloud Identity Access Governance offers a powerful and integrated solution. By strategically implementing these tools, businesses can effectively bridge the on-premise and cloud divide, ensuring robust security, streamlined operations, and unwavering compliance across their entire, interconnected SAP landscape. This holistic approach is not just about meeting regulatory requirements; it's about building a resilient and secure foundation for digital transformation.
