Software supply chain attacks are among the most sophisticated cyber threats, targeting information systems by compromising third-party software, builds, or trusted interfaces. By exploiting these dependencies, threat actors can introduce malicious backdoors into otherwise secure environments without detection.
Why are software supply chain attacks a major risk for SAP?
The catastrophic SolarWinds attack demonstrated how third-party software can be weaponized to compromise vast networks, impacting hundreds of Fortune 500 companies and government agencies, including the Pentagon and the State Department. For SAP landscapes, the risk is equally severe. SAP environments rely on complex ecosystems of third-party add-ons, open-source components, and external interfaces, each representing a potential entry point for attackers to bypass traditional perimeter security.
How to mitigate supply chain risks in SAP
Securing an SAP landscape against supply chain threats requires aligning with the Cyber Supply Chain Risk Management (C-SCRM) practices recommended by the National Institute of Standards and Technology (NIST). Key strategies include:
- Minimize Third-Party Dependencies: Reduce the number of external software components and third-party add-ons within your SAP landscape.
- Restrict External Connections: Audit and limit external interfaces to those strictly necessary for business operations.
- Audit Open Source Components: Avoid using unverified open-source components, as these are frequent targets for supply chain compromise.
- Continuous Monitoring: Implement robust monitoring for all third-party software to detect anomalous behavior or unauthorized changes.
Expert Guidance: Securing Your SAP Landscape
Layer Seven Security has developed a comprehensive whitepaper detailing the threat vectors that could be exploited to compromise third-party software within SAP environments. The whitepaper provides a roadmap for hardening your supply chain, minimizing external exposure, and implementing NIST-aligned risk management practices.

Frequently Asked Questions
What is a software supply chain attack?
A software supply chain attack targets an organization by compromising its third-party software, build processes, or trusted interfaces. Instead of attacking the target directly, attackers compromise a supplier, allowing them to distribute malware or backdoors to the supplier’s downstream customers.
How do NIST C-SCRM practices apply to SAP?
NIST Cyber Supply Chain Risk Management (C-SCRM) practices provide a framework for identifying, assessing, and mitigating risks throughout the software lifecycle. For SAP, this means vetting all third-party add-ons, strictly controlling external connections, and maintaining visibility into all software components.
Why is monitoring third-party software important?
Monitoring is critical because supply chain attacks often involve the introduction of backdoors that remain dormant or operate stealthily. Continuous monitoring of third-party software behavior allows security teams to detect unauthorized changes or unusual network activity that could indicate a compromise.
