Security Policy

Mission Statement

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.

Guardrails

Prohibited Activities

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

Permitted Activities

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

Reporting a Vulnerability

Scope

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

How to Report

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

What to Expect

  • 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)

Coordinated Vulnerability Disclosure (CVD)

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)

Security Measures

Code Security

  • 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

Dependency Management

  • 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

Secrets Management

  • 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

Infrastructure Security

  • 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

CI/CD Security

  • 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

Security Scanning

Automated Scans

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

Scan Schedule

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

Failure Thresholds

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

Secure Development Practices

Code Review Checklist

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

Testing Requirements

Security-relevant code must include:

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

Compliance and Policies

Data Handling

  • 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)

Access Control

  • 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

Incident Response

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

Contact

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

Acknowledgments

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

  • (Contributors will be listed here with their permission)

Updates

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

License and Legal

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.
