Managing cybersecurity for SAP systems requires addressing unpatched vulnerabilities, ransomware, credentials compromise, system interfaces, and access controls. This report, based on the 2023 Cybersecurity Threats to SAP Systems Report, outlines actionable strategies to secure your environment using SAP ALM platforms and the Cybersecurity Extension for SAP.
Executive Summary
The 2023 landscape for SAP security is dominated by persistent challenges: unpatched systems, ransomware, and compromised credentials. According to survey data from over 205 security professionals, while organizations are heavily invested in platforms like Solution Manager, Focused Run, and Cloud ALM—with 81% of customers utilizing at least one—less than half are fully leveraging their capabilities. This gap leaves critical systems exposed to threats that could otherwise be mitigated through automated patching, rigorous access controls, and enhanced monitoring.
Effective SAP security is not merely about software updates; it is a holistic approach that secures the application, database, and operating system layers. By automating the discovery of vulnerabilities, restricting unauthorized OS commands, and enforcing robust identity management, organizations can significantly reduce their attack surface. This article provides targeted recommendations for the five most significant threats identified in the report, offering a roadmap for IT and security teams to move from reactive patching to proactive defense.
Key Takeaways
- Unpatched systems, ransomware, and credentials compromise remain the most significant cybersecurity threats to SAP environments.
- 81% of SAP customers use ALM platforms, yet fewer than 50% are fully utilizing their security capabilities.
- System Recommendations (SysRec) in SAP Solution Manager automates the discovery and prioritization of critical security patches.
- The Cybersecurity Extension for SAP provides cross-layer protection against ransomware and improves vulnerability detection.
- Proactive security requires restricting RFC destinations and enforcing the principle of least privilege for all user accounts.
How can I manage SAP security patching?
Keeping up with the volume of security patches is the most significant challenge for SAP customers, often complicated by scheduling downtime and validating manual corrections. System Recommendations (SysRec) in SAP Solution Manager simplifies this by automating the discovery of security notes based on your specific installed software components. You can prioritize “Hot News” and high-priority patches, identify impacted objects to create targeted test plans, and automate the staging of corrections. To further improve reliability and remove false positives, the Cybersecurity Extension for SAP can be integrated to refine the patch reporting process.
How can I protect SAP systems against ransomware?
Ransomware targets SAP applications by exploiting vulnerable interfaces, OS commands, and file uploads. To mitigate this, restrict access to OS commands like RSBDCOS0, SM49, and CG3Z, and disable vulnerable ICF services such as SOAP RFC and WEB RFC. Ensure the SAP Virus Scan Interface is enabled to detect malware in file uploads. Beyond the application layer, you must secure the underlying OS by closing unnecessary ports and monitoring root or sudo actions, particularly those involving file execution. The Cybersecurity Extension for SAP is designed to provide comprehensive protection across the application, database, and OS layers.
How can I prevent credentials compromise in SAP?
Preventing credentials compromise requires a combination of network encryption and strict identity governance. Use SNC and SSL to protect SAP protocols and encoded passwords during communication, and disable downwards-compatible passwords to ensure strong hashing algorithms are used. Enforce robust password policies and secure logon tickets and cookies against misuse. For advanced protection, leverage the Cybersecurity Extension for SAP to activate Anomaly Detection, which identifies unusual user actions, such as logins from new terminals or unexpected transaction execution.
How can I secure SAP system interfaces?
System interfaces are a major attack vector, and their security should be managed through strict access controls and monitoring. Restrict program starts and server registrations on the gateway server, and provision RFC users based on the principle of least privilege. You should also enable Unified Connectivity (UCON) to protect sensitive remote-enabled function modules (RFMs). For ongoing visibility, deploy Interface and Connection Monitoring (ICMon) in SAP Solution Manager or Integration and Exception Monitoring in SAP Focused Run to alert on unauthorized or abnormal interface usage.
How can I improve SAP access controls?
Effective access control requires strict segregation of duties and the removal of excessive permissions. Do not use the SAPALL profile in productive systems, ensure standard users are locked, and change default passwords. Enforce authorization checks for all RFMs and sensitive system operations, and use switchable authorization checks where applicable. The Cybersecurity Extension for SAP can assist by automatically discovering users with administrative permissions or conflicting functions, allowing you to maintain a clean and secure authorization environment.
Frequently Asked Questions
What are the top three threats to SAP systems in 2023?
According to the report, the three most significant threats are unpatched systems, ransomware attacks, and credentials compromise. These threats consistently rank highest among security professionals across various industries and regions.
How do ALM platforms help with SAP security?
Platforms like SAP Solution Manager, Focused Run, and Cloud ALM provide tools for automating security note implementation, monitoring system interfaces, and managing patches. While 81% of customers use these tools, many do not fully leverage their potential for security automation.
Why is the Cybersecurity Extension for SAP recommended?
The Cybersecurity Extension for SAP enhances existing ALM investments by removing false positives in patch reporting, providing cross-layer ransomware protection (application, database, and OS), and offering advanced anomaly detection for user behavior.
