+# Security Features in Pytrickle
+
+## Overview
+
+Pytrickle includes built-in security middleware to protect servers against malformed requests, security scans, and various attack vectors. The security features are enabled by default and can be customized through configuration.
+
+## Features
+
+### 1. Protocol Error Handling
+- **HTTP/2 Protocol Errors**: Gracefully handles `BadHttpMessage` errors that occur when scanners probe for HTTP/2 support
+- **Malformed Request Handling**: Catches and properly responds to malformed HTTP requests
+- **Clean Error Responses**: Returns appropriate HTTP status codes without exposing internal server details
+
+### 2. Rate Limiting
+- **Per-IP Rate Limiting**: Configurable requests per minute per IP address (default: 50/minute)
+- **Sliding Window**: Uses efficient sliding window algorithm for accurate rate limiting
+- **Memory Management**: Automatic cleanup of old request records
+
+### 3. Request Validation
+- **HTTP Method Filtering**: Only allows standard HTTP methods (GET, POST, PUT, DELETE, HEAD, OPTIONS, PATCH)
+- **Content-Length Validation**: Prevents oversized requests (default: 10MB limit)
+- **User-Agent Blocking**: Configurable blocking of specific user agent patterns
+- **Suspicious Pattern Detection**: Logs requests with suspicious patterns (path traversal, XSS, SQL injection attempts)
+
+### 4. Security Headers
+All responses include comprehensive security headers:
+- `X-Content-Type-Options: nosniff` - Prevents MIME type sniffing
+- `X-Frame-Options: DENY` - Prevents clickjacking attacks
+- `X-XSS-Protection: 1; mode=block` - Enables XSS protection
+- `Strict-Transport-Security` - Enforces HTTPS connections
+- `Referrer-Policy: strict-origin-when-cross-origin` - Controls referrer information
+- `Content-Security-Policy: default-src 'self'` - Restricts resource loading
+- `Server: pytrickle` - Hides detailed server version information
+
+### 5. Enhanced Logging
+- **Security Event Logging**: Logs suspicious requests and security violations
+- **Performance Monitoring**: Tracks request duration and response codes
+- **IP-based Tracking**: Associates all security events with client IP addresses
+
+## Usage
+
+### Basic Usage (Default Security)
+
+```python
+from pytrickle import StreamProcessor
+
+# Security is enabled by default with reasonable settings
+processor = StreamProcessor(
+    video_processor=my_video_processor,
+    port=8000
+)
+```
+
+### Custom Security Configuration
+
+```python
+from pytrickle import StreamProcessor, SecurityConfig
+
+# Create custom security configuration
+security_config = SecurityConfig(
+    rate_limit_requests=100,  # 100 requests per minute
+    rate_limit_window=60,     # 1 minute window
+    max_request_size=5 * 1024 * 1024,  # 5MB limit
+    blocked_user_agents={'badbot', 'scanner'},
+    log_all_requests=True,    # Log all requests (verbose)
+    log_suspicious_requests=True
+)
+
+processor = StreamProcessor(
+    video_processor=my_video_processor,
+    port=8000,
+    security_config=security_config
+)
+```
+
+### Disabling Security (Not Recommended)
+
+```python
+from pytrickle import StreamProcessor
+
+# Disable security middleware (not recommended for production)
+processor = StreamProcessor(
+    video_processor=my_video_processor,
+    port=8000,
+    enable_security=False
+)
+```
+
+### Using StreamServer Directly
+
+```python
+from pytrickle import StreamServer, SecurityConfig
+
+security_config = SecurityConfig(
+    rate_limit_requests=25,  # Stricter rate limiting
+    custom_security_headers={
+        'X-Custom-Header': 'MyValue'
+    }
+)
+
+server = StreamServer(
+    frame_processor=my_processor,
+    port=8000,
+    security_config=security_config,
+    enable_security=True
+)
+```
+
+## Configuration Options
+
+### SecurityConfig Parameters
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `rate_limit_enabled` | bool | `True` | Enable/disable rate limiting |
+| `rate_limit_requests` | int | `50` | Max requests per window per IP |
+| `rate_limit_window` | int | `60` | Rate limit window in seconds |
+| `max_request_size` | int | `10MB` | Maximum request size in bytes |
+| `blocked_user_agents` | Set[str] | `set()` | User agent patterns to block |
+| `allowed_methods` | Set[str] | Standard HTTP | Allowed HTTP methods |
+| `security_headers_enabled` | bool | `True` | Enable security headers |
+| `custom_security_headers` | Dict[str,str] | `{}` | Additional custom headers |
+| `log_suspicious_requests` | bool | `True` | Log suspicious patterns |
+| `log_all_requests` | bool | `False` | Log all requests (verbose) |
+
+### StreamProcessor/StreamServer Parameters
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `security_config` | SecurityConfig | `None` | Custom security config (uses defaults if None) |
+| `enable_security` | bool | `True` | Enable/disable security middleware |
+
+## Security Event Logging
+
+The security middleware provides detailed logging:
+
+```
+# Rate limit violations
+2025-10-01 16:26:09 [WARNING] Rate limit exceeded for 192.168.1.100
+
+# Suspicious request patterns  
+2025-10-01 16:26:10 [WARNING] Suspicious request pattern from 192.168.1.100: GET /../../etc/passwd
+
+# Malformed HTTP requests
+2025-10-01 16:26:11 [INFO] Malformed HTTP request from 192.168.1.100: BadHttpMessage(400, message: Pause on PRI/Upgrade)
+
+# Blocked user agents
+2025-10-01 16:26:12 [WARNING] Blocked user agent: BadBot/1.0 from 192.168.1.100
+```
+
+## Performance Impact
+
+The security middleware is designed for minimal performance impact:
+- **Efficient Data Structures**: Uses deque for O(1) rate limiting operations
+- **Memory Management**: Automatic cleanup prevents memory leaks
+- **Non-blocking**: All operations are asynchronous and non-blocking
+- **Minimal Overhead**: < 1ms overhead for normal requests
+
+## Integration with Existing Applications
+
+For applications already using pytrickle, security is automatically enabled when upgrading. To maintain existing behavior:
+
+```python
+# Maintain existing behavior (no security)
+processor = StreamProcessor(
+    video_processor=my_processor,
+    enable_security=False  # Explicitly disable
+)
+```
+
+## Best Practices
+
+1. **Keep Security Enabled**: Always use security middleware in production
+2. **Monitor Logs**: Regularly review security event logs
+3. **Tune Rate Limits**: Adjust rate limits based on your application's needs
+4. **Custom Headers**: Add application-specific security headers as needed
+5. **Update Regularly**: Keep pytrickle updated for latest security improvements
+
+## Advanced Usage
+
+### Custom Middleware Stack
+
+```python
+from pytrickle.security import create_security_middleware_stack, SecurityConfig
+
+# Create custom middleware stack
+security_config = SecurityConfig(rate_limit_requests=25)
+middleware_stack = create_security_middleware_stack(
+    config=security_config,
+    enable_error_handling=True,
+    enable_security_middleware=True,
+    enable_logging=True
+)
+
+# Use with StreamServer
+server = StreamServer(
+    frame_processor=my_processor,
+    middleware=middleware_stack,
+    enable_security=False  # Disable default, use custom
+)
+```
+
+### Blocking Specific Patterns
+
+```python
+security_config = SecurityConfig(
+    blocked_user_agents={
+        'badbot',
+        'scanner',
+        'crawler'
+    },
+    # Block requests with suspicious patterns
+    log_suspicious_requests=True
+)
+```
+
+## Migration from Custom Security
+
+If you were using custom security middleware:
+
+```python
+# Old approach (custom middleware)
+from my_security import create_security_middleware_stack
+processor = StreamProcessor(
+    video_processor=my_processor,
+    middleware=create_security_middleware_stack()
+)
+
+# New approach (built-in security)
+from pytrickle import SecurityConfig
+security_config = SecurityConfig(
+    rate_limit_requests=50,
+    log_all_requests=False
+)
+processor = StreamProcessor(
+    video_processor=my_processor,
+    security_config=security_config
+)
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Rate Limiting Too Strict**: Increase `rate_limit_requests` or `rate_limit_window`
+2. **Legitimate Requests Blocked**: Review `blocked_user_agents` and suspicious pattern detection
+3. **Performance Issues**: Disable verbose logging (`log_all_requests=False`)
+4. **Security Scan Errors**: These are now handled gracefully and logged appropriately
+
+### Debug Logging
+
+Enable debug logging to see detailed security middleware operation:
+
+```python
+import logging
+logging.getLogger('pytrickle.security').setLevel(logging.DEBUG)
+```
