# Security Policy for Auth Module

This document outlines security procedures and policies for the Auth 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: Auth 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 `Auth` 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 Auth Module

### Authentication Security

- **Password Storage**: Passwords should never be stored in plaintext. Use secure hashing algorithms (bcrypt, argon2) with proper salting.
- **Token Security**: Authentication tokens are cryptographically signed and have configurable expiration times.
- **API Key Management**: API keys are generated using cryptographically secure random generators.

### Authorization Security

- **Principle of Least Privilege**: Users are granted only the minimum permissions necessary for their role.
- **Permission Validation**: All permission checks are performed server-side and cannot be bypassed by clients.
- **Role-Based Access Control (RBAC)**: The module supports RBAC for fine-grained access control.

### Session Security

- **Token Expiration**: Tokens have configurable expiration times (default: 1 hour).
- **Token Revocation**: Tokens can be revoked immediately when needed (e.g., logout, security breach).
- **Refresh Tokens**: Secure token refresh mechanism to extend sessions without re-authentication.

### Common Vulnerabilities Mitigated

1. **Brute Force Attacks**: Rate limiting should be implemented on authentication endpoints.
2. **Credential Stuffing**: Monitor for unusual authentication patterns.
3. **Session Hijacking**: Use secure, HttpOnly cookies for web applications.
4. **Token Leakage**: Never log authentication tokens; use secure transmission (HTTPS).

## Best Practices for Using This Module

- Always use the latest stable version of the module.
- Enable TLS/HTTPS for all authentication traffic.
- Implement rate limiting on authentication endpoints.
- Use strong password policies and multi-factor authentication where possible.
- Regularly rotate API keys and tokens.
- Monitor authentication logs for suspicious activity.
- Follow the principle of least privilege when configuring access or permissions.
- Regularly review configurations and logs for suspicious activity.

## Secure Configuration

```python
# Example secure configuration
from codomyrmex.auth import Authenticator

authenticator = Authenticator()

# Configure token expiration (default: 3600 seconds)
# authenticator.token_manager.set_expiration(3600)

# Use API key authentication for service-to-service communication
# Use username/password for end-user authentication
```

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