# Security Policy

## Supported Versions

We actively maintain and provide security updates for the following versions:

| Version | Supported          |
| ------- | ------------------ |
| 1.0.x   | :white_check_mark: |

## Reporting a Vulnerability

We take security vulnerabilities seriously. If you discover a security vulnerability in this n8n infrastructure, please report it responsibly.

### How to Report

1. **Do NOT** open a public GitHub issue for security vulnerabilities
2. Send an email to: security@your-domain.com (replace with your actual security contact)
3. Include the following information:
   - Description of the vulnerability
   - Steps to reproduce the issue
   - Potential impact assessment
   - Suggested fix (if available)

### What to Expect

- **Acknowledgment**: Within 48 hours of your report
- **Initial Assessment**: Within 7 days
- **Fix Timeline**: Critical issues within 14 days, others within 30 days
- **Disclosure**: Coordinated disclosure after fix is released

## Security Best Practices

### For Administrators

1. **Environment Variables**:
   - Never commit `.env` files to version control
   - Use GitHub Secrets for all sensitive data
   - Rotate encryption keys regularly (quarterly recommended)

2. **Database Security**:
   - Always use SSL connections to Supabase
   - Enable Row Level Security (RLS) policies
   - Regular backup encryption validation
   - Monitor for unusual database activity

3. **Container Security**:
   - Keep n8n version pinned and updated
   - Regular security scanning of Docker images
   - Use non-root user inside containers
   - Limit container network access

4. **Access Control**:
   - Enable n8n user management
   - Use strong JWT secrets
   - Implement webhook authentication
   - Regular access review and cleanup

### For Developers

1. **Code Security**:
   - No hardcoded credentials in source code
   - Validate all webhook inputs
   - Sanitize user inputs in workflows
   - Use prepared statements for database queries

2. **Workflow Security**:
   - Audit workflow permissions regularly
   - Secure credential storage in n8n
   - Validate external API responses
   - Implement proper error handling

3. **AI Integration Security**:
   - Validate AI model outputs
   - Sanitize prompts and inputs
   - Secure API key management
   - Monitor AI usage and costs

## Security Checklist

### Pre-Deployment
- [ ] All secrets configured in GitHub repository
- [ ] Database SSL enforcement enabled
- [ ] Container security scan passed
- [ ] Webhook authentication configured
- [ ] Network security policies reviewed

### Post-Deployment  
- [ ] Health monitoring enabled
- [ ] Backup encryption verified
- [ ] Access logs configured
- [ ] Incident response plan ready
- [ ] Security contact information updated

### Regular Maintenance
- [ ] Monthly security updates applied
- [ ] Quarterly credential rotation
- [ ] Backup integrity verification
- [ ] Security audit review
- [ ] Vulnerability scanning

## Known Security Considerations

1. **Hugging Face Spaces**: Public spaces expose the application URL. Use authentication and access controls.

2. **Vector Embeddings**: Knowledge base content may contain sensitive information. Review before indexing.

3. **Webhook Endpoints**: Publicly accessible URLs should implement proper authentication.

4. **Database Access**: Ensure Supabase RLS policies are properly configured for your use case.

## Incident Response

In case of a security incident:

1. **Immediate Actions**:
   - Disable affected services if necessary
   - Preserve logs and evidence
   - Assess scope and impact

2. **Communication**:
   - Notify security team immediately
   - Prepare user communication if needed
   - Coordinate with stakeholders

3. **Recovery**:
   - Apply security patches
   - Restore from clean backups if needed
   - Verify system integrity
   - Update security measures
