Security Policy

🔒 Security Overview

Codex Extended implements multiple layers of security to ensure safe operation across different environments.

🚨 Reporting Security Vulnerabilities

If you discover a security vulnerability, please report it responsibly:

Contact Information

• Email: security@codex.dev (placeholder)
• GitHub Security Advisories: Create a new advisory

Reporting Process

1. Do not create public issues for security vulnerabilities
2. Email security@codex.dev with details
3. Include reproduction steps and potential impact
4. We will acknowledge receipt within 48 hours
5. We will provide regular updates on our progress

🛡️ Security Measures

Code Security

• Rust Memory Safety: All core components use Rust for memory safety
• Dependency Scanning: Automated vulnerability checks in CI/CD
• Code Review: Required for all security-related changes
• Static Analysis: Clippy and custom linting rules

Runtime Security

• Sandboxing: Process isolation using Linux namespaces/Windows containers
• Permission Model: Least privilege execution
• Input Validation: Comprehensive input sanitization
• Audit Logging: All operations are logged for forensic analysis

Network Security

• MCP Protocol: Secure WebSocket communication
• TLS Encryption: All network communications encrypted
• Authentication: Token-based authentication for API access

🔧 Security Best Practices

For Contributors

• Never commit secrets: Use environment variables or secure vaults
• Validate inputs: All user inputs must be validated and sanitized
• Handle errors securely: Don't leak sensitive information in error messages
• Use secure defaults: Security should be enabled by default

For Users

• Keep dependencies updated: Regularly update to latest versions
• Use sandboxed execution: Run untrusted code in isolated environments
• Monitor logs: Regularly review audit logs for suspicious activity
• Secure configuration: Use strong passwords and secure API keys

📊 Security Metrics

Vulnerability Response Time

• Critical: < 24 hours
• High: < 72 hours
• Medium: < 1 week
• Low: < 2 weeks

Code Coverage

• Security-critical code: > 90% test coverage
• Core functionality: > 80% test coverage
• Integration tests: Required for all security features

🔍 Security Tools

Automated Security Scanning

• Cargo Audit: Rust dependency vulnerability scanning
• Clippy: Security-focused linting rules
• Trivy: Container and filesystem scanning
• Dependabot: Automated dependency updates

Manual Security Reviews

• Code Review: Required for security-related PRs
• Architecture Review: Major changes reviewed by security team
• Penetration Testing: Regular security assessments

📋 Security Checklist for Contributors

Pre-commit

• No secrets committed to repository
• All inputs validated and sanitized
• Error messages don't leak sensitive information
• Secure defaults enabled

Code Review

• Security implications documented
• Input validation implemented
• Authentication/authorization checked
• Audit logging added for sensitive operations

Testing

• Security test cases added
• Fuzz testing performed on parsers
• Integration tests include security scenarios
• Performance impact of security measures measured

🚩 Known Security Considerations

Architecture Security

• MCP Communication: WebSocket connections should use TLS in production
• Agent Isolation: Sub-agents run in isolated processes/environments
• Resource Limits: CPU/memory limits prevent resource exhaustion attacks

Third-party Dependencies

• Regular Updates: Dependencies updated quarterly minimum
• Vulnerability Monitoring: Automated alerts for new vulnerabilities
• License Compliance: All dependencies reviewed for license compatibility

Data Protection

• Encryption at Rest: Sensitive data encrypted when stored
• Encryption in Transit: All network communications encrypted
• Data Minimization: Only collect necessary data
• Retention Policies: Data deleted according to retention schedules
