OWASP ZAP Interview Questions
Interviewing for a security-aware QA or AppSec-adjacent role that uses OWASP ZAP? Practice with an AI that asks about passive versus active scanning, spidering an app, using ZAP as an intercepting proxy, automating DAST scans in CI/CD, and interpreting findings against the OWASP Top 10.

What you’ll be asked.
OWASP ZAP interviews focus on dynamic application security testing (DAST) fundamentals and how to fold automated security scanning into a delivery pipeline. Expect questions on the difference between passive scanning (observing traffic without attacking) and active scanning (actively probing for vulnerabilities), spidering and AJAX spidering to discover URLs, and using ZAP as a proxy to inspect and manipulate requests. You will be asked how to automate ZAP (baseline scans, the ZAP API, CI integration), how to handle authentication so scans reach protected pages, how to triage findings and false positives, and how results map to the OWASP Top 10. The theme is shifting security testing left without drowning the team in noise.
Topics covered.
Key areas interviewers evaluate when asking about owasp zap.
Passive vs Active Scanning
Observing traffic safely versus actively probing for vulnerabilities.
Spidering & Discovery
Crawling an app (including AJAX spider) to find URLs and attack surface.
Intercepting Proxy
Using ZAP as a proxy to inspect and manipulate requests and responses.
Automation in CI
Baseline scans, the ZAP API, and running DAST on every build.
Authenticated Scans
Handling login and sessions so scans reach protected pages.
OWASP Top 10
Mapping findings to common vulnerability classes and triaging false positives.

Frequently Asked Questions
What is OWASP ZAP?
OWASP ZAP (Zed Attack Proxy) is a free, open-source DAST tool that finds vulnerabilities in running web applications. It works as an intercepting proxy and scanner, supporting passive observation, active probing, spidering, and automation via its API and CI integrations.
What is the difference between passive and active scanning?
Passive scanning observes traffic and flags issues without attacking the app, so it is safe to run anywhere. Active scanning actively sends crafted requests to probe for vulnerabilities, which is more thorough but can modify data, so it belongs on test environments, not production.
How does ZAP fit into CI/CD?
Teams commonly run a ZAP baseline scan against a deployed test build on every pipeline run, failing or warning on new findings. Authenticated scans and the ZAP API enable deeper coverage. The goal is shifting security left while keeping noise manageable.
Can I practice OWASP ZAP questions on AssertHired?
Yes. The AI interviewer asks DAST, scanning, and CI-integration questions with follow-ups and scores you across four dimensions.
