This repository implements a defense-only CVE matter-analysis pipeline for blue-team security operations. All code, analysis, and tooling must support defensive security purposes exclusively.

This system and repository MUST NOT be used for:

• ❌ Exploit payload generation - Do not create or distribute exploit code
• ❌ Offensive security operations - No penetration testing tools or attack frameworks
• ❌ Cryptographic breaking - No attempts to break or weaken cryptographic systems
• ❌ Malware development - No malicious software of any kind
• ❌ Unauthorized access - No tools for gaining unauthorized system access

This system IS DESIGNED FOR:

• ✅ Vulnerability analysis - Defensive analysis of CVE data
• ✅ Risk assessment - Prioritizing vulnerabilities for remediation
• ✅ Threat detection - Identifying patterns in vulnerability data
• ✅ Security monitoring - Tracking changes in the threat landscape
• ✅ Defense planning - Supporting blue-team security operations

We accept vulnerability reports for:

• Security vulnerabilities in this codebase
• Vulnerabilities in dependencies
• Misconfigurations that could lead to security issues
• Authentication or authorization bypasses
• Information disclosure issues
• Any code that violates our defense-only mission

DO NOT create public GitHub issues for security vulnerabilities.

Instead, please report security issues privately:

1. Email: Send details to the security team at security@example.com (replace with actual contact)
2. Subject: Start with [SECURITY] followed by a brief description
3. Include:
   • Description of the vulnerability
   • Steps to reproduce
   • Potential impact
   • Suggested fix (if known)
   • Your contact information

• Acknowledgment: Within 48 hours of your report
• Initial Assessment: Within 5 business days
• Updates: At least every 10 days until resolution
• Resolution: We aim to fix critical vulnerabilities within 30 days
• Credit: We will credit reporters (unless you prefer anonymity)

We follow responsible disclosure practices:

1. Private Disclosure: Report to us privately first
2. Coordinated Timeline: We'll work with you on a disclosure timeline
3. Public Disclosure: After a fix is deployed and users have time to update
4. Default Timeline: 90 days from initial report (can be adjusted)

• Input Validation: All external inputs are sanitized and validated
• Output Encoding: All outputs are properly encoded to prevent injection
• Parameterized Queries: Database queries use parameterization
• Error Handling: Errors don't expose sensitive system information
• Least Privilege: Components run with minimal required permissions

• Version Pinning: All dependencies use exact version pins
• Regular Scanning: Automated scanning for known vulnerabilities
• Timely Updates: Security patches applied within 7 days
• Minimal Dependencies: Only necessary packages are included
• Trusted Sources: Dependencies from reputable, verified sources

• No Secrets in Code: API keys, passwords, tokens never in source code
• Environment Variables: Secrets passed via environment or secret managers
• Secret Rotation: Regular rotation of credentials and API keys
• Access Control: Secrets accessible only to authorized services
• Audit Logging: All secret access is logged

• Container Security: Docker images scanned with Trivy
• Runtime Security: gVisor provides container isolation on GKE
• Network Policies: Kubernetes network policies restrict traffic
• RBAC: Role-based access control for all Kubernetes resources
• Encryption: Data encrypted in transit (TLS) and at rest

• Branch Protection: Main branch requires reviews and passing CI
• Code Review: All changes require at least one review
• Automated Scanning: CodeQL and dependency scanning on all PRs
• Signed Commits: Encourage or require GPG-signed commits
• Audit Trails: All CI/CD actions logged and auditable

We run the following security scans:

1. CodeQL (Python): Static analysis for security vulnerabilities
2. Trivy: Container image vulnerability scanning
3. Dependency Check: Known vulnerabilities in Python packages
4. SAST: Static application security testing
5. Secret Scanning: Detect accidentally committed secrets

• Every PR: CodeQL, dependency check
• Every commit to main: All scans
• Weekly: Full security audit
• Before release: Comprehensive security review

• HIGH/CRITICAL vulnerabilities: CI fails, must be fixed before merge
• MEDIUM vulnerabilities: Warning, should be fixed promptly
• LOW vulnerabilities: Tracked, fixed in regular maintenance

Before approving any PR, reviewers should verify:

• No hardcoded secrets or credentials
• Input validation for all external data
• Proper error handling (no sensitive info in errors)
• SQL queries use parameterization
• Authentication and authorization properly implemented
• Sensitive data encrypted in transit and at rest
• New dependencies scanned for vulnerabilities
• Defense-only stance maintained (no exploits/offensive tools)
• Documentation updated for security-relevant changes

Security-relevant code must include:

• Unit tests for input validation
• Tests for authentication/authorization logic
• Tests for error handling
• Integration tests for security controls

• CVE Data: Public data from NVD, no restrictions
• Logs: May contain system information, retained for 90 days
• Metrics: Aggregated, anonymized performance data
• User Data: Not applicable (system-to-system integration)

• Code Access: GitHub repository access via organization membership
• Production Access: Restricted to SRE and security teams
• Secrets Access: Limited to CI/CD and production services
• Audit Logs: Retained for 1 year, reviewed quarterly

In the event of a security incident:

1. Contain: Isolate affected systems immediately
2. Assess: Determine scope and impact
3. Notify: Alert security team and stakeholders
4. Remediate: Apply fixes and deploy updates
5. Review: Post-incident analysis and lessons learned
6. Document: Update runbooks and procedures

• Security Team: security@example.com (replace with actual)
• On-Call: Via PagerDuty/incident management system
• Security Lead: TBD (assign a security champion)

We appreciate security researchers who responsibly disclose vulnerabilities. Hall of fame for contributors:

• (Contributors will be listed here with their permission)

This security policy is reviewed and updated quarterly. Last updated: 2025-11-13

By reporting a vulnerability, you agree to:

• Allow us reasonable time to remediate before public disclosure
• Not exploit the vulnerability beyond what's necessary to demonstrate it
• Not access, modify, or delete data without authorization
• Follow coordinated disclosure practices

We commit to:

• Respond to reports promptly and professionally
• Keep you informed of remediation progress
• Credit you for the discovery (unless you prefer anonymity)
• Not take legal action for responsible security research

Remember: This is a DEFENSE-ONLY system. Any attempt to use this code for offensive purposes, exploit generation, or cryptographic attacks violates this security policy and the project's core mission.
