# Security Policy for Networking Module

This document outlines security procedures and policies for the Networking module.

## Reporting a Vulnerability

If you discover a security vulnerability within this module, please report it to us as soon as possible.
We take all security reports seriously.

**DO NOT report security vulnerabilities through public GitHub issues.**

Instead, please email security@codomyrmex.dev with the subject line: "SECURITY Vulnerability Report: Networking Module - [Brief Description]".

Please include the following information in your report:

- A description of the vulnerability and its potential impact.
- Steps to reproduce the vulnerability, including any specific configurations or conditions required.
- Any proof-of-concept code or examples.
- The version(s) of the module affected.
- Your name and contact information (optional).

We aim to acknowledge receipt of your vulnerability report within 2-3 business days and will work with you to understand and remediate the issue. We may request additional information if needed.

Public disclosure of the vulnerability will be coordinated with you after the vulnerability has been fixed and an update is available, or after a reasonable period if a fix is not immediately possible.

## Security Updates

Security patches and updates for this module will be documented in the module changelog and released as part of regular version updates. Critical vulnerabilities may warrant out-of-band releases.

## Scope

This security policy applies only to the `Networking` module within the Codomyrmex project. For project-wide security concerns, please refer to the main project's security policy or contact the core project maintainers.

## Security Considerations for Networking Module

### Transport Layer Security

- **TLS/SSL**: All network communications should use TLS 1.2 or higher.
- **Certificate Verification**: SSL certificates must be verified by default.
- **Certificate Pinning**: Optional certificate pinning for high-security scenarios.

### Connection Security

- **Timeout Configuration**: Prevent resource exhaustion with proper timeouts.
- **Connection Pooling**: Secure connection reuse with proper lifecycle management.
- **Proxy Support**: Secure proxy configuration for controlled network access.

### WebSocket Security

- **Origin Validation**: Verify WebSocket connection origins.
- **Message Validation**: Validate all incoming WebSocket messages.
- **Connection Limits**: Prevent resource exhaustion from excessive connections.

### Common Vulnerabilities Mitigated

1. **Man-in-the-Middle (MITM)**: TLS encryption and certificate verification.
2. **Server-Side Request Forgery (SSRF)**: URL validation and allowlisting.
3. **Denial of Service (DoS)**: Timeouts, rate limiting, and connection limits.
4. **DNS Rebinding**: Host header validation and IP allowlisting.
5. **Open Redirects**: URL validation before following redirects.

### Network Security Best Practices

- Never trust user-provided URLs without validation.
- Use allowlists for permitted hosts and IP ranges.
- Implement circuit breakers for external service calls.
- Monitor network traffic for anomalies.

## Best Practices for Using This Module

- Always use the latest stable version of the module.
- Enable TLS/HTTPS for all network communications.
- Verify SSL certificates (never disable verification in production).
- Configure appropriate timeouts for all connections.
- Implement retry logic with exponential backoff.
- Use connection pooling to manage resources efficiently.
- Log network errors for monitoring and debugging.
- Validate URLs before making requests.
- Use IP allowlists for sensitive internal services.
- Follow the principle of least privilege when configuring access or permissions.
- Regularly review configurations and logs for suspicious activity.

## Secure Configuration

```python
# Example secure networking configuration
from codomyrmex.networking import HTTPClient, WebSocketClient

# Configure HTTP client with security defaults
http_client = HTTPClient(
    timeout=30,
    verify_ssl=True,  # Always verify SSL certificates
    max_redirects=5,
    allowed_hosts=["api.trusted-service.com"]
)

# Configure WebSocket client securely
ws_client = WebSocketClient(
    url="wss://secure.example.com/socket",
    verify_ssl=True,
    origin="https://yourapp.com"
)

# Always handle connection errors gracefully
try:
    response = http_client.get("https://api.example.com/data")
except NetworkError as e:
    logger.error(f"Network request failed: {e}")
```

## Security Audit Checklist

- [ ] TLS 1.2+ is enforced for all connections
- [ ] SSL certificate verification is enabled
- [ ] Timeouts are configured for all connections
- [ ] URL validation is implemented
- [ ] Host allowlisting is configured where appropriate
- [ ] Connection limits are set to prevent DoS
- [ ] Proxy settings are secured (if used)
- [ ] Network errors are logged appropriately
- [ ] Retry logic includes proper backoff
- [ ] WebSocket origins are validated

Thank you for helping keep Codomyrmex and the Networking module secure.
