dast-scanning

Q: How do I install dast-scanning?

Run npx skills add https://github.com/bagelhole/devops-security-agent-skills --skill dast-scanning in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/dast-scanning/ (personal) or .claude/skills/dast-scanning/ (project).

Common DAST Findings

OWASP Top 10

owasp_findings:
  A01_Broken_Access_Control:
    - IDOR vulnerabilities
    - Missing function-level access control
    - Privilege escalation
    
  A02_Cryptographic_Failures:
    - Sensitive data in URLs
    - Missing HTTPS
    - Weak ciphers
    
  A03_Injection:
    - SQL injection
    - Command injection
    - XSS
    
  A05_Security_Misconfiguration:
    - Default credentials
    - Verbose error messages
    - Missing security headers
    
  A07_Auth_Failures:
    - Weak passwords accepted
    - Session fixation
    - Missing MFA

Security Headers Check

# Check security headers
curl -I https://target.example.com | grep -i "x-\|content-security\|strict"

# Expected headers:
# X-Content-Type-Options: nosniff
# X-Frame-Options: DENY
# X-XSS-Protection: 1; mode=block
# Content-Security-Policy: default-src 'self'
# Strict-Transport-Security: max-age=31536000

Custom Test Cases

# Test authentication
tests:
  - name: "Authentication Bypass"
    steps:
      - Access protected resource without auth
      - Verify 401/403 response
      - Access with valid auth
      - Verify 200 response
    
  - name: "Session Management"
    steps:
      - Login and capture session token
      - Logout
      - Attempt to use old session
      - Verify session invalidated
    
  - name: "Input Validation"
    steps:
      - Submit XSS payload in all inputs
      - Submit SQL injection in all inputs
      - Verify proper sanitization

Common Issues

Issue: False Positives

Problem: Scanner reports non-vulnerabilities Solution: Configure scan policy, review findings manually

Issue: Missing Authentication

Problem: Cannot scan authenticated areas Solution: Configure authentication context, use session tokens

Issue: Incomplete Coverage

Problem: Scanner misses endpoints Solution: Import API specs, improve spidering, use authenticated scanning

Best Practices

Test in staging environment first
Configure proper authentication
Import API specifications for complete coverage
Review findings before reporting
Combine with manual testing
Run regular scans (weekly minimum)
Track findings over time
Coordinate with development team
