What is “flow-based vulnerability scanning”?
Flow-based vulnerability scanning is a security analysis method that identifies vulnerabilities by examining how data moves through software, rather than simply looking for known vulnerable components or patterns. This approach traces data flows between inputs, processing logic, system interfaces, and outputs to detect unsafe behaviors such as unauthorized data access, insecure communications, or improper privilege use.
By analyzing these interactions, flow-based scanning can uncover complex vulnerabilities such as data leakage, privilege escalation paths, insecure inter-process communication, or exposed interfaces that traditional signature-based scanning might miss. This method provides deeper visibility into how software actually behaves, rather than just what components it contains.
Flow-based analysis is especially valuable in firmware, system apps, and embedded environments where vulnerabilities often arise from the interaction between components. It enables more accurate risk identification, reduces false positives, and helps security teams understand the real-world impact and exploitability of vulnerabilities.
