What signals and metrics do you track to operate OWASP Dependency-Check well?
Quick Answer
For OWASP Dependency-Check, watch vulnerable dependencies by CVSS, count of suppressed findings, and the age of the local NVD data feed (stale feeds miss recent CVEs). Trend them over time; a single scan is a snapshot, the trend tells you if you are getting more secure or just accumulating debt.
Detailed Answer
Operating a scanner is not "turn it on" — it needs the same observability as any production system. For OWASP Dependency-Check, the signals that matter are vulnerable dependencies by CVSS, count of suppressed findings, and the age of the local NVD data feed (stale feeds miss recent CVEs).
Trend them. Rising Critical counts on a stable codebase usually means a base image or dependency has aged, not that developers got careless. A rising false-positive rate is an early warning that the gate is about to lose the team's trust. Scan duration matters because a slow gate is a gate people route around.
Feed these into a dashboard alongside remediation SLAs so security posture is visible to the people who own it, not buried in a tool nobody logs into.
Code Example
# Signals to track for OWASP Dependency-Check # vulnerable dependencies by CVSS, count of suppressed findings, and the age of the local NVD data feed (stale feeds miss recent CVEs) # rule: trend over time, don't react to a single scan # rule: watch false-positive rate as closely as finding count
Interview Tip
Name false-positive rate as a leading indicator — it shows you understand adoption, not just scanning.
