+# Standards - Web Application Vulnerability Triage
+
+## Primary Standards
+
+### OWASP Risk Rating Methodology
+- **URL**: https://owasp.org/www-community/OWASP_Risk_Rating_Methodology
+- **Purpose**: Structured approach to evaluating likelihood and impact of web vulnerabilities
+
+### OWASP Top 10 (2021)
+- **URL**: https://owasp.org/www-project-top-ten/
+- **Categories**: A01 through A10 covering the most critical web application security risks
+
+### OWASP Web Security Testing Guide v4.2
+- **URL**: https://owasp.org/www-project-web-security-testing-guide/
+- **Relevance**: Manual validation techniques for scanner findings
+
+### CWE/SANS Top 25 Most Dangerous Software Weaknesses
+- **URL**: https://cwe.mitre.org/top25/
+- **Relevance**: Maps findings to common weakness enumeration for categorization
+
+### CVSS v3.1 / v4.0
+- **URL**: https://www.first.org/cvss/
+- **Relevance**: Industry standard vulnerability scoring complementing OWASP risk rating

+# Workflows - Web Application Vulnerability Triage
+
+## Workflow 1: DAST Finding Triage
+1. Import DAST scan results (ZAP XML/JSON, Burp XML)
+2. Auto-classify findings by OWASP Top 10 category via CWE mapping
+3. Filter out known false positive patterns (missing headers on non-sensitive pages, etc.)
+4. Flag confirmed exploitation findings as true positives
+5. Queue remaining findings for manual validation
+6. Security analyst validates with manual testing in Burp/ZAP
+7. Assign OWASP risk rating to validated findings
+8. Push validated findings to DefectDojo/Jira
+
+## Workflow 2: SAST Finding Triage
+1. Import SAST scan results (Semgrep JSON, SonarQube)
+2. Filter out findings in test files, example code, and dead code
+3. Cross-reference against data flow analysis for injection findings
+4. Review code context to validate exploitability
+5. Assign severity based on data sensitivity and exposure
+6. Create development tickets for validated findings
+
+## Workflow 3: Combined Triage and Deduplication
+1. Import both DAST and SAST findings for same application
+2. Correlate SAST code findings with DAST runtime findings
+3. Findings confirmed by both DAST and SAST get elevated priority
+4. Deduplicate findings pointing to same root cause
+5. Generate unified triage report with remediation priority
