Securing Your Migration to SAP S/4HANA
Key Takeaways
Migrating to S/4HANA poses significant security challenges due to differences in authentication models, data structures, and potential vulnerabilities in custom code.
Insecure SAP applications in cloud environments can be compromised in under three hours, with an average of 2500 vulnerabilities present in custom programs that might be exploited by attackers.
The whitepaper 'Securing the Journey to SAP S/4HANA' offers a framework for secure migration, detailing best practices and recommendations to protect installations and support compliance monitoring.
Migrating to S/4HANA is a significant security challenge, especially when combined with transitioning to the cloud and moving custom code from SAP ERP.
The challenges are due to considerable differences between S/4HANA and SAP ERP. Authentication and authorization models differ significantly between the solutions. There are also differences in data structures, communication protocols, cross-system interfaces, and many other areas. Security challenges also arise from the migration of custom code in ERP to S/4HANA. Custom programs intended for use in internal ERP systems can be more vulnerable to exploitation in S/4HANA installations that are often hosted in the cloud.
The impact of security failures for S/4HANA migrations can be critical. Insecure SAP applications in cloud environments can be discovered and compromised in less than 3 hours. SAP customers have an average of 2500 vulnerabilities within their custom programs that may be exploited by threat actors to bypass authentication, inject malicious code, and modify data in SAP systems.
The whitepaper Securing the Journey to SAP S/4HANA provides a comprehensive framework for securely migrating from SAP ERP to S/4HANA. The framework details security best practices and SAP recommendations for S/4HANA across twelve domains. The whitepaper will enable you to protect S/4HANA installations in the cloud and on-premise, secure custom developments migrated from ERP, and implement automated compliance and security monitoring for S/4HANA.
