Read **Executive Summary** first 2. Review deployment recommendation 3. Approve remediation plan and resources 4. Sign off on timeline ### For Security Team 1. Review **Comprehensive Security Audit** 2. Validate findings and CVSS scores 3. Review **Remediation Plan** technical approach 4. Approve security fixes before deployment ### For Development Team 1. Start with **Remediation Plan** 2. Use **Security Checklist** for daily progress 3. Reference **Comprehensive Audit** for technical details 4. Follow TDD approach with provided test examples ### For Product Management 1. Review **Executive Summary** 2. Understand timeline and resource requirements 3. Approve delay to production deployment 4. Plan feature work around security fixes --- ## Key Decisions Required ### Immediate (Within 24 hours) - [ ] **Decision:** Approve 4-week remediation timeline? - [ ] **Decision:** Allocate 1 FTE developer for security fixes? - [ ] **Decision:** Halt any production deployment plans? - [ ] **Decision:** Restrict current access to trusted networks only? ### Short-Term (Week 1) - [ ] **Decision:** Approve Phase 1 security fixes? - [ ] **Decision:** Schedule security review meeting? - [ ] **Decision:** Engage third-party penetration testers? ### Medium-Term (Month 1) - [ ] **Decision:** Implement automated security scanning in CI/CD? - [ ] **Decision:** Establish bug bounty program? - [ ] **Decision:** Schedule regular security audits? --- ## Success Criteria ### Phase 1 Complete When: - ✅ All critical vulnerabilities fixed - ✅ Security regression tests pass - ✅ Code review approved by senior engineer - ✅ Security review approved by security team ### Production Ready When: - ✅ All 4 phases complete - ✅ Code coverage >85% - ✅ Penetration testing passed - ✅ Documentation complete and reviewed - ✅ Monitoring and alerting configured - ✅ Staging deployment successful - ✅ Security team sign-off received - ✅ Executive sponsor approval granted --- ## Contact Information **Questions About:** **Audit Findings:** - Security Team: security@company.com - Audit Lead: audit-lead@company.com **Implementation:** - Engineering Lead: engineering@company.com - Development Team: dev-team@company.com **Timeline/Resources:** - Product Management: product@company.com - Project Manager: pm@company.com **Approvals:** - Executive Sponsor: exec-sponsor@company.com --- ## Document History | Version | Date | Changes | Author | |---------|------|---------|--------| | 1.0 | 2025-01-28 | Initial security audit complete | Claude Code Security Audit | --- ## Related Resources ### Internal Documentation - Project README: `/code/scout_mcp/README.md` - Implementation plans: `/code/scout_mcp/docs/plans/` ### External References - OWASP Top 10 (2021): https://owasp.org/Top10/ - OWASP ASVS v4.0: https://owasp.org/www-project-application-security-verification-standard/ - NIST Cybersecurity Framework: https://www.nist.gov/cyberframework - CWE-78 (Command Injection): https://cwe.mitre.org/data/definitions/78.html - CWE-22 (Path Traversal): https://cwe.mitre.org/data/definitions/22.html - asyncssh Security Docs: https://asyncssh.readthedocs.io/en/latest/api.html#security --- ## Appendices ### A.
