Run existing SecurityAuditor with all scanners enabled 2. Execute npm audit for dependency vulnerabilities 3. Run additional static analysis tools 4. Generate initial findings report ### Phase 2: Manual Review 1. Review high-risk code areas identified by automated scanning 2. Analyze security-critical components (TokenManager, SecurityMonitor, etc.) 3. Review MCP-specific attack vectors 4. Validate suppression configurations ### Phase 3: Validation 1. Verify false positives vs. true positives 2. Confirm suppression reasons are valid 3. Test security controls effectiveness 4. Document any new findings ### Phase 4: Risk Assessment 1. Calculate risk scores for each finding 2. Prioritize based on exploitability and impact 3. Identify quick wins vs. long-term improvements 4. Create remediation timeline ### Phase 5: Reporting 1. Generate comprehensive security report 2. Create executive summary 3. Document remediation recommendations 4. Track findings in GitHub issues ## Security Rules Coverage ### Current Rules (Implemented) - **OWASP Top 10**: A01, A03, A05, A07 - **CWE**: CWE-22, CWE-79, CWE-89, CWE-798 - **DollhouseMCP Specific**: DMCP-SEC-001 through DMCP-SEC-010 ### Additional Rules Needed - **OWASP**: A02 (Cryptographic Failures), A04 (Insecure Design), A06 (Vulnerable Components), A08 (Software and Data Integrity), A09 (Security Logging), A10 (SSRF) - **CWE**: CWE-287 (Authentication), CWE-862 (Authorization), CWE-502 (Deserialization) - **MCP Specific**: Element interaction security, Portfolio sync security, Collection submission security ## Suppression Strategy ### Valid Suppression Categories 1. **Test Files**: Security patterns for testing 2. **Security Modules**: Security implementation code 3. **False Positives**: Confirmed non-issues 4. **Type Definitions**: Non-executable code 5. **Documentation**: Markdown and comments ### Suppression Review Process 1. Validate each suppression reason 2. Ensure suppressions are specific (not overly broad) 3. Document security decisions 4. Regular suppression audit ## Success Metrics ### Coverage Metrics - Code coverage: >95% of security-critical paths - Rule coverage: All OWASP Top 10 categories - Suppression ratio: <20% of findings suppressed - False positive rate: <10% ### Quality Metrics - Critical findings: 0 unresolved - High findings: <5 with remediation plan - Medium findings: Tracked and prioritized - Low findings: Documented for future work ### Process Metrics - Audit frequency: Monthly automated, quarterly comprehensive - Remediation time: Critical <24hrs, High <7 days - Issue tracking: 100% findings tracked - Documentation: All decisions documented ## Tools and Resources ### Existing Tools - SecurityAuditor (built-in) - npm audit - GitHub security features - CodeQL (GitHub Actions) ### Additional Tools Recommended - Semgrep: Custom rule creation - TruffleHog: Entropy-based secret detection - Snyk: Comprehensive vulnerability database - OWASP Dependency Check: CVE correlation ### Documentation - Security rules documentation - Suppression configuration guide - Remediation playbooks - Security best practices guide ## Continuous Improvement ### Feedback Loop 1.
