With SAP’s strategic shift towards cloud platforms like SAP Business Technology Platform (BTP), ABAP development increasingly moves beyond traditional on-premise systems to cloud environments. While cloud adoption offers scalability, agility, and integration benefits, it also introduces new security challenges and potential attack vectors.
This article explores essential security considerations for cloud-based ABAP development to prevent security breaches, data leaks, and unauthorized access—commonly referred to as SAP ABAP crimes—in modern cloud landscapes.
¶ 1. Multi-Tenancy and Shared Infrastructure
- Cloud environments host multiple customers on shared infrastructure, raising risks of data leakage or cross-tenant attacks.
- Strict isolation and robust access controls are mandatory to prevent unauthorized data access.
¶ 2. Expanded Attack Surface
- Cloud exposes APIs, web services, and external interfaces that increase exposure to attacks such as injection, cross-site scripting, or DDoS.
- ABAP code integrating with cloud services must handle these vectors carefully.
¶ 3. Dynamic and Distributed Environments
- Development, testing, and deployment span multiple cloud services and locations.
- Ensuring consistent security policies and controls across distributed components is complex but critical.
¶ 4. Identity and Access Management Complexity
- Cloud platforms use federated identity management with SSO, OAuth, and token-based authentication.
- ABAP applications must integrate securely with these mechanisms without weakening authorization models.
-
Follow standard SAP ABAP secure coding guidelines, emphasizing:
- Proper authorization checks (
AUTHORITY-CHECK).
- Avoiding dynamic SQL injection.
- Input validation and output encoding.
-
Pay extra attention to APIs exposed externally in cloud applications.
¶ 2. Authentication and Authorization
- Leverage SAP Cloud Identity services for user authentication.
- Implement fine-grained authorization controls using SAP Cloud roles and scopes.
- Validate all tokens and session information rigorously within ABAP code.
¶ 3. Data Protection and Encryption
- Encrypt sensitive data both at rest and in transit.
- Use SAP Cloud Platform Key Management Service (KMS) or similar tools for key lifecycle management.
- Avoid storing sensitive data in unprotected logs or application variables.
¶ 4. Logging and Monitoring
- Integrate ABAP logging with centralized cloud monitoring and SIEM systems.
- Monitor for anomalous access patterns or API abuse.
- Enable alerting on suspicious activities to enable rapid incident response.
- Securely connect ABAP code to other cloud services using HTTPS, OAuth tokens, and certificates.
- Regularly audit and rotate credentials used by ABAP applications to connect externally.
- Use DevSecOps practices to integrate static code analysis, vulnerability scanning, and security testing in CI/CD pipelines.
- Enforce code review policies and automated security gate checks before deployment.
When exposing an ABAP API as an OData service on SAP BTP:
- Implement strict authorization checks in service methods.
- Validate incoming request parameters to prevent injection attacks.
- Use HTTPS and OAuth bearer tokens for authentication.
- Log API usage including caller identity and access time.
| Security Aspect |
Cloud Consideration |
Recommended Practice |
| Authorization |
Federated roles and scopes |
Map cloud roles to ABAP authority objects |
| Data Encryption |
Cloud data at rest and in transit |
Use platform encryption and secure channels |
| Logging & Monitoring |
Centralized cloud logging & SIEM integration |

Cloud-based ABAP development brings transformative benefits but requires heightened security vigilance. By adopting secure coding principles, enforcing strong authentication and authorization, protecting data, and integrating with cloud-native security monitoring, SAP developers can minimize risks of ABAP-related security crimes in the cloud.
Secure cloud ABAP development ensures your SAP landscapes remain resilient against evolving threats while harnessing the power and flexibility of cloud technologies.
