+# File Upload Security Documentation
+
+## Overview
+
+The ivatar application now includes comprehensive file upload security features to protect against malicious file uploads, data leaks, and other security threats.
+
+## Security Features
+
+### 1. File Type Validation
+
+**Magic Bytes Verification**
+
+- Validates file signatures (magic bytes) to ensure uploaded files are actually images
+- Supports JPEG, PNG, GIF, WebP, BMP, and TIFF formats
+- Prevents file extension spoofing attacks
+
+**MIME Type Validation**
+
+- Uses python-magic library to detect actual MIME types
+- Cross-references with allowed MIME types list
+- Prevents MIME type confusion attacks
+
+### 2. Content Security Scanning
+
+**Malicious Content Detection**
+
+- Scans for embedded scripts (`<script>`, `javascript:`, `vbscript:`)
+- Detects executable content (PE headers, ELF headers)
+- Identifies polyglot attacks (files valid in multiple formats)
+- Checks for PHP and other server-side code
+
+**PIL Image Validation**
+
+- Uses Python Imaging Library to verify file is a valid image
+- Checks image dimensions and format
+- Ensures image can be properly loaded and processed
+
+### 3. EXIF Data Sanitization
+
+**Metadata Removal**
+
+- Automatically strips EXIF data from uploaded images
+- Prevents location data and other sensitive metadata leaks
+- Preserves image quality while removing privacy risks
+
+### 4. Enhanced Logging
+
+**Security Event Logging**
+
+- Logs all file upload attempts with user ID and IP address
+- Records security violations and suspicious activity
+- Provides audit trail for security monitoring
+
+## Configuration
+
+### Settings
+
+All security features can be configured in `config.py` or overridden in `config_local.py`:
+
+```python
+# File upload security settings
+ENABLE_FILE_SECURITY_VALIDATION = True
+ENABLE_EXIF_SANITIZATION = True
+ENABLE_MALICIOUS_CONTENT_SCAN = True
+```
+
+### Dependencies
+
+The security features require the following Python packages:
+
+```bash
+pip install python-magic>=0.4.27
+```
+
+**Note**: On some systems, you may need to install the libmagic system library:
+
+- **Ubuntu/Debian**: `sudo apt-get install libmagic1`
+- **CentOS/RHEL**: `sudo yum install file-devel`
+- **macOS**: `brew install libmagic`
+
+## Security Levels
+
+### Security Score System
+
+Files are assigned a security score (0-100) based on validation results:
+
+- **90-100**: Excellent - No security concerns
+- **80-89**: Good - Minor warnings, safe to process
+- **70-79**: Fair - Some concerns, review recommended
+- **50-69**: Poor - Multiple issues, high risk
+- **0-49**: Critical - Malicious content detected, reject
+
+### Validation Levels
+
+1. **Basic Validation**: File size, filename, extension
+2. **Magic Bytes**: File signature verification
+3. **MIME Type**: Content type validation
+4. **PIL Validation**: Image format verification
+5. **Security Scan**: Malicious content detection
+6. **EXIF Sanitization**: Metadata removal
+
+## API Reference
+
+### FileValidator Class
+
+```python
+from ivatar.file_security import FileValidator
+
+validator = FileValidator(file_data, filename)
+results = validator.comprehensive_validation()
+```
+
+### Main Validation Function
+
+```python
+from ivatar.file_security import validate_uploaded_file
+
+is_valid, results, sanitized_data = validate_uploaded_file(file_data, filename)
+```
+
+### Security Report Generation
+
+```python
+from ivatar.file_security import get_file_security_report
+
+report = get_file_security_report(file_data, filename)
+```
+
+## Error Handling
+
+### Validation Errors
+
+The system provides user-friendly error messages while logging detailed security information:
+
+- **Malicious Content**: "File appears to be malicious and cannot be uploaded"
+- **Invalid Format**: "File format not supported or file appears to be corrupted"
+
+### Logging Levels
+
+- **INFO**: Successful uploads and normal operations
+- **WARNING**: Security violations and suspicious activity
+- **ERROR**: Validation failures and system errors
+
+## Testing
+
+### Running Security Tests
+
+```bash
+python manage.py test ivatar.test_file_security
+```
+
+### Test Coverage
+
+The test suite covers:
+
+- Valid file validation
+- Malicious content detection
+- Magic bytes verification
+- MIME type validation
+- EXIF sanitization
+- Form validation
+- Integration tests
+
+## Performance Considerations
+
+### Memory Usage
+
+- Files are processed in memory for validation
+- Large files (>5MB) may impact performance
+- Consider increasing server memory for high-volume deployments
+
+### Processing Time
+
+- Basic validation: <10ms
+- Full security scan: 50-200ms
+- EXIF sanitization: 100-500ms
+- Total overhead: ~200-700ms per upload
+
+## Troubleshooting
+
+### Common Issues
+
+1. **python-magic Import Error**
+
+   - Install libmagic system library
+   - Verify python-magic installation
+
+2. **False Positives**
+   - Review security score thresholds
+   - Adjust validation settings
+
+### Debug Mode
+
+Enable debug logging to troubleshoot validation issues:
+
+```python
+LOGGING = {
+    "loggers": {
+        "ivatar.security": {
+            "level": "DEBUG",
+        },
+    },
+}
+```
+
+## Security Best Practices
+
+### Deployment Recommendations
+
+1. **Enable All Security Features** in production
+2. **Monitor Security Logs** regularly
+3. **Keep Dependencies Updated**
+4. **Regular Security Audits** of uploaded content
+
+### Monitoring
+
+- Monitor security.log for violations
+- Track upload success/failure rates
+- Alert on repeated security violations
+
+## Future Enhancements
+
+Potential future improvements:
+
+- Virus scanning integration (ClamAV)
+- Content-based image analysis
+- Machine learning threat detection
+- Advanced polyglot detection
+- Real-time threat intelligence feeds

+# Testing
+
+## Running Tests
+
+### Local Development (Recommended)
+For local development, use the provided script to skip Bluesky tests that require external API credentials:
+
+```bash
+./run_tests_local.sh
+```
+
+This runs all tests except those marked with `@pytest.mark.bluesky`.
+
+### All Tests
+To run all tests including Bluesky tests (requires Bluesky API credentials):
+
+```bash
+python3 manage.py test -v2
+```
+
+### Specific Test Categories
+```bash
+# Run only Bluesky tests
+python3 manage.py test ivatar.ivataraccount.test_views_bluesky -v2
+
+# Run only file upload security tests
+python3 manage.py test ivatar.test_file_security -v2
+
+# Run only upload tests
+python3 manage.py test ivatar.ivataraccount.test_views -v2
+```
+
+## Test Markers
+
+Tests are categorized using pytest markers:
+- `@pytest.mark.bluesky`: Tests requiring Bluesky API credentials
+- `@pytest.mark.slow`: Long-running tests
+- `@pytest.mark.integration`: Integration tests
+- `@pytest.mark.unit`: Unit tests
