COMPARING STATIC AND RUNTIME REACHABILITY

Summary from the TLDR InfoSec newsletter

This article compares static and runtime reachability, two emerging approaches to determining whether vulnerabilities in code dependencies are actually exploitable. Both offer package-level and function-level capabilities. Static reachability analyzes code repositories to identify potential vulnerabilities during development but can't eliminate false positives completely, while runtime reachability uses agents to monitor actual code execution and provide near-certain identification of exploitable vulnerabilities. Static reachability integrates well with development workflows and doesn't require agent deployment. Runtime reachability offers superior accuracy in identifying truly exploitable vulnerabilities but requires agent installation and currently has limited vendor support.
