OWASP Web Application Security Testing Checklist

OWASP Web Application Security Testing Checklist

Table of Contents

Information Gathering

  • Manually explore the site
  • Spider/crawl for missed or hidden content
  • Check for files that expose content, such as robots.txt, sitemap.xml, .DS_Store
  • Check the caches of major search engines for publicly accessible sites
  • Check for differences in content based on User Agent (eg, Mobile sites, access as a Search engine Crawler)
  • Perform Web Application Fingerprinting
  • Identify technologies used
  • Identify user roles
  • Identify application entry points
  • Identify client-side code
  • Identify multiple versions/channels (e.g. web, mobile web, mobile app, web services)
  • Identify co-hosted and related applications
  • Identify all hostnames and ports
  • Identify third-party hosted content

Configuration Management

  • Check for commonly used application and administrative URLs
  • Check for old, backup and unreferenced files
  • Check HTTP methods supported and Cross Site Tracing (XST)
  • Test file extensions handling
  • Test for security HTTP headers (e.g. CSP, X-Frame-Options, HSTS)
  • Test for policies (e.g. Flash, Silverlight, robots)
  • Test for non-production data in live environment, and vice-versa
  • Check for sensitive data in client-side code (e.g. API keys, credentials)

Secure Transmission

  • Check SSL Version, Algorithms, Key length
  • Check for Digital Certificate Validity (Duration, Signature and CN)
  • Check credentials only delivered over HTTPS
  • Check that the login form is delivered over HTTPS
  • Check session tokens only delivered over HTTPS
  • Check if HTTP Strict Transport Security (HSTS) in use

Authentication

  • Test for user enumeration

Session Management

  • Establish how session management is handled in the application (eg, tokens in cookies, token in URL)

Cryptography

  • Check if data which should be encrypted is not
