  24. 24. Intro to the API • RESTish – ok, only uses GET/POST requests http(s)://zap/<format>/<component>/ <operation>/<op name>[/?<params>] • Maps closely to the UI / code • Theres a v basic (but complete) web UI for it • And clients in various langs: Java, Python, Node JS, .Net, PHP, Go … • Clients are generated from the code 25
  25. 25. API UI – Top Level
  26. 26. API Pro Tips 1. Experiment with the Desktop UI 2. Export configs from the UI (contexts, scan policies..) 3. Then reproduce using the API UI 4. Finally convert to a script 27
  27. 27. Intro – Python API • Install from pypi: pip install python-owasp-zap-v2.4 • In your script: from zapv2 import ZAPv2 zap = ZAPv2() zap = ZAPv2(proxies={ 'http': 'http://localhost:8080', 'https': 'http://localhost:8090'}) 28 h from zapv2 import ZAPv2 zap = ZAPv2( apikey='mysupersecretkey', proxies={ 'http': 'http://localhost:8090', 'https': 'http://localhost:8090'}) • zap.urlopen(target) • pip install python-owasp-zap-v2.4
  28. 28. Exploring • Proxy Regression / Unit tests • Traditional Spider (crawler) • Ajax Spider (browsers) • Spider SOAP definition (via alpha add-on) • Spider Swagger/ OpenAPI definition (via alpha add-on) • Import ModSecurity2 logs (via alpha add-on) 29
  29. 29. Spider Desktop and API UIs
  30. 30. Spider Desktop and API UIs
  31. 31. Exploring – Trad Spider 32 h id = zap.spider.scan(target) • time.sleep(5) • while int(zap.spider.status(id)) < 100: • print ('Spider progress %: ' + zap.spider.status(id)) • time.sleep(5) • print ('Spider completed')
  32. 32. Exploring – Ajax Spider 33 h id = zap.ajaxSpider.scan(target) • time.sleep(5) • while zap.ajaxSpider.status(id) == 'running': • print ('Ajax Spider # results: ' + zap.ajaxSpider.number_of_results(id)) • time.sleep(5) • print ('Ajax Spider completed')
  33. 33. Scanning – Passive Scan 34 while int(zap.pscan.records_to_scan) > 0: • print ('Pscan records : ' + zap.pscan.records_to_scan) • time.sleep(5) • print ('Pscan completed') h • Passive scanning happens automatically when proxying • To tell when its finished:
  34. 34. Scanning – Active Scan 35 h id = zap.ascan.scan(target) • time.sleep(5) • while int(zap.ascan.status(id)) < 100: • print ('Ascan progress %: ' + zap.ascan.status(id)) • time.sleep(5) • print ('Ascan completed')
  35. 35. Reporting – HTML + XML 36 h # HTML Report • with open ('report.html', 'w') as f: f.write(zap.core.htmlreport()) # XML Report • with open ('report.xml', 'w') as f: f.write(zap.core.xmlreport())
  36. 36. Reporting – all alert data 37 h # Use paging for lots of alerts • offset = 0; page = 5000 • alerts = zap.core.alerts('', offset, page) • while len(alerts) > 0: • for alert in alerts: • # Do whatever you want with alert • offset += page • alerts = zap.core.alerts('', offset, page)
  37. 37. And dont forget... 38 h # Your work here is done... • zap.core.shutdown()
  38. 38. Authenticating • Authentication can be hard :( • Simple form based auth should be ok • Authentication scripts should be able to handle anything • But if you have complex SSO or equiv you may want a simpler option in your test env • Pro Top: use the UI to set authentication up! 39
  39. 39. Tuning - speed • Spider time limits • Data driven content • Technology • Active scan • Scan rules • Input vectors • Attack strength 40
  40. 40. Tuning - feedback • Active scan stats • Response stats • Authentication stats (alpha add-on) • Statsd support 41
  41. 41. Tuning - accuracy • Attack thresholds • Rule configuration – Forms that dont need CSRF tokens – Increase timing attacks from 5 seconds 42
  42. 42. And if you need help... • ZAP Getting Started Guide • ZAP User Guide • ZAP User Group • ZAP Developer Group • ZAP wiki, includes links to videos • irc.mozilla.com #websectools 43
  43. 43. Talk Summary • Use the baseline scan for a quick security overview • Use the mass baseline to create a dashboard • Use the new Jenkins plugin for more depth • Use the ZAP API for even more control • If you need help, just ask :) 44
