Runtime Dependency Detection

Runtime Dependency Detection (RTO) is the process of identifying all software components and libraries actually loaded during application execution. Unlike static analysis, which examines code at rest, RTO uses system-level monitoring (e.g., eBPF, kernel tracing) to capture dependencies loaded through dynamic linking, reflection, or environment-specific configurations. This aligns with NIST SP 800-161 and the EU Cyber Resilience Act's requirements for comprehensive software transparency. It ensures that the Software Bill of Materials (SBOM) reflects the actual attack surface, including transitive dependencies that only appear in specific runtime environments. This capability is critical for companies operating under the US Executive Order 14028, which mandates verifiable SBOMs for federal software procurement.

Implementation typically follows a three-tier approach: 1) Observability Integration—deploying eBPF-based sensors or lightweight agents across production clusters to monitor load events. 2) Reconciliation—cross-referencing runtime-detected dependencies with static SBOMs to identify 'ghost dependencies' or unauthorized libraries. 3) Automated Remediation—triggering alerts or-zero-trust-based-blocking when a high-risk vulnerability (e.g., Log4j-style RTO) is detected in a running process. A global manufacturing firm implemented this approach, reducing their Mean Time to Detect (MTTD) for zero-day vulnerabilities by 70% and achieving 100% compliance with the EU AI Act's software transparency requirements within six months.

Taiwan enterprises face three primary challenges: Performance Overhead, Data Silos, and Regulatory Ambiguity. First, RTO can impact system latency; the solution is to use kernel-level probes (eBPF) which offer minimal overhead. Second, many companies have fragmented tools where static and runtime data cannot be merged; adopting CycloneDX as a unified SBOM format solves this. Third, the lack of specific domestic regulation on RTO creates uncertainty; however, the upcoming EU AI Act and US Executive Order 14028 make RTO-ready SBOMs a prerequisite for international market access. We recommend a phased approach: start with high-risk internet-facing services before scaling to internal systems.
