Preventing Unauthorized Indirect Access to SAP Systems

Unauthorized indirect access is a significant concern in SAP licensing, which could result in substantial financial implications for organizations.

This article provides a comprehensive overview of unauthorized indirect access, the potential risks, and actionable strategies for prevention. It will explore the concept in detail, ensuring an accessible and practical understanding for all readers.

What is Unauthorized Indirect Access?

Unauthorized indirect access refers to a scenario in SAP environments where users or third-party systems gain access to SAP data or functionalities without proper licensing. Unlike direct access, where a user interacts directly with SAP software through the standard interface, indirect access involves accessing the SAP system via intermediary software or non-SAP applications.

Examples include:

• A third-party customer relationship management (CRM) system pulls customer data from SAP.
• A web portal that allows users to interact with SAP inventory information indirectly.
• A mobile application that makes updates to SAP in the background.

Indirect access has become a key challenge for organizations, as if not managed correctly, it can potentially lead to licensing compliance issues, unexpected costs, and legal complications.

The Risks of Unauthorized Indirect Access

Organizations need to understand the potential risks of unauthorized indirect access to prevent financial, operational, and reputational damage:

• Non-compliance penalties: SAP’s licensing model requires licenses for every person or system that accesses the SAP data, whether directly or indirectly. Failure to meet this requirement could lead to hefty fines.
• Unexpected licensing costs: Organizations are often unaware of the indirect access occurring within their environment. When discovered by an SAP audit, companies may face sudden financial burdens due to unplanned licensing purchases.
• Operational disruptions: If unauthorized access is detected, SAP may require immediate rectification, impacting system availability and disrupting operations.
• Reputational damage: Non-compliance can harm a company’s reputation, affecting relationships with customers, partners, and stakeholders. A publicized compliance failure may lead to distrust and impact future business opportunities.
• Legal consequences: Unauthorized indirect access could also result in legal action by SAP, leading to prolonged disputes, additional costs, and resource allocation challenges.

Common Scenarios Leading to Unauthorized Indirect Access

Understanding where indirect access occurs is the first step to preventing it. Here are some common scenarios that might lead to unauthorized indirect access:

1. Third-party CRM Integration: A CRM system that pulls data, such as customer order details, from the SAP system. Each individual accessing CRM data sourced from SAP might require an SAP license.
2. E-commerce Platform: A customer-facing website interacting with SAP inventory information to check stock availability and prices. Each customer performing this action might trigger indirect access requirements.
3. Business Intelligence (BI) Tools: BI applications connecting to SAP to extract data for reporting or analysis purposes can cause issues if proper licensing is not accounted for.
4. Supplier Portals: Supplier portals that allow vendors to view purchase orders or update delivery statuses can trigger indirect access requirements, especially if these interactions involve direct updates to SAP data.
5. Custom Applications: Custom-built applications that interact with SAP, such as mobile apps for sales representatives, can inadvertently lead to indirect access violations if they are not correctly licensed.
6. Internet of Things (IoT) Devices: IoT devices that collect data and feed it into SAP for analysis or inventory tracking can also lead to unauthorized indirect access if proper licenses are not in place.

Preventive Strategies for Unauthorized Indirect Access

Organizations should adopt a structured approach to mitigate the risk of unauthorized indirect access.

Here are some effective strategies to consider:

1. Know Your SAP Licensing Terms

SAP licensing can be complex, and each company may have unique licensing agreements. It is critical to:

• Review the terms of your contract with SAP, paying special attention to indirect access clauses.
• Clarify ambiguities: Reach out to your SAP account representative for explanations about licensing ambiguities.
• Negotiate License Terms: If possible, negotiate your license terms to include provisions for indirect access, especially if your organization relies heavily on third-party integrations.

Example: The definition of a “Named User” can vary between contracts. Make sure you understand how SAP defines indirect users within your specific agreement.

2. Map Data Flows and System Integrations

One of the most effective ways to prevent unauthorized indirect access is to have full visibility over your system’s data flows. This can be achieved through:

• Integration Mapping: Document all interfaces between SAP and non-SAP systems to determine which external applications interact with SAP.
• Audit Trails: Regularly track data requests and system integrations to identify unauthorized connections.
• Identify High-Risk Integrations: Focus on high-risk integrations where multiple users or systems may indirectly access SAP data.

Example: Conduct a quarterly review of all systems interacting with SAP to ensure each is properly documented and compliant.

3. Adopt SAP’s Digital Access Licensing Model

SAP introduced the Digital Access Licensing Model to simplify indirect access licensing. Under this model, customers are charged based on document usage rather than individual users’ indirect access to the system.

• Documents Covered: This model covers sales orders, invoices, and purchase orders.
• Flexibility: It provides more cost flexibility and predictability, helping organizations manage indirect access more effectively.
• Cost Management: Digital Access can help reduce overall costs by focusing on document-based pricing rather than user-based pricing, making it easier for businesses to understand and manage their licensing obligations.

Example: The Digital Access model could simplify licensing compliance if your organization primarily processes sales orders through a third-party application.

4. Regular Internal Audits and Compliance Checks

Conducting internal audits can prevent indirect access from spiraling into non-compliance.

• Establish a Compliance Team: Create a dedicated team to regularly monitor and verify SAP access.
• Use Monitoring Tools: Utilize tools such as SAP Solution Manager or third-party monitoring software to track access and pinpoint unauthorized indirect interactions.
• Document Findings: Keep detailed records of audit findings and remediation actions to demonstrate compliance during official SAP audits.
• Frequency: Increase the frequency of compliance checks as your IT landscape evolves, especially during significant system changes or new integrations.

Example: A bi-annual compliance audit involving IT, finance, and procurement teams to review all system access points.

5. Limit Access via API Management

Restricting API access can help prevent unintended indirect access.

• API Gateways: Utilize API management solutions to restrict which applications can connect to SAP systems.
• Granular Permissions: Apply role-based access controls (RBAC) to ensure only authorized users and applications can access SAP data through APIs.
• Rate Limiting: Implement rate limiting for APIs to control the number of data requests and reduce the risk of unauthorized data usage.

Example: Use an API gateway to limit an external reporting tool’s access to only non-sensitive SAP data, preventing any unlicensed data exchanges.

6. Engage SAP Licensing Experts

The complexity of SAP’s licensing models often necessitates specialized expertise.

• Licensing Consultancy: Engage with consultants specializing in SAP licensing to ensure your environment remains compliant.
• Workshops and Training: Conduct regular training sessions for your IT and compliance teams to keep them updated on best practices.
• Audit Simulation: Have SAP licensing experts perform mock audits to identify potential compliance gaps before an official SAP audit occurs.

Example: Partnering with an SAP licensing consultant to conduct a workshop for IT staff on the nuances of indirect access.
