⚡ Quick Start

Installation

pip install fastapi-fortify

Basic Usage

from fastapi import FastAPI
from fastapi_fortify import SecurityMiddleware

app = FastAPI()
app.add_middleware(SecurityMiddleware)  # That's it! 🎉

@app.get("/")
async def hello():
    return {"message": "Hello, secure world!"}

🛡️ Features

Core Security Components

• 🔥 WAF Protection - Blocks SQL injection, XSS, path traversal, command injection
• 🤖 Bot Detection - Advanced behavioral analysis and user agent filtering
• 🚫 IP Blocklist - Static/dynamic blocking with threat intelligence feeds
• ⏱️ Rate Limiting - Sliding window algorithms with Redis/memory backends
• 👤 Auth Monitoring - Brute force detection and webhook processing
• 📊 Management API - RESTful endpoints for monitoring and configuration

Advanced Features

• Zero Configuration - Works out of the box with sensible defaults
• Environment Presets - Development, Production, High-Security configurations
• Threat Intelligence - Automatic updates from security feeds
• Performance Optimized - Minimal latency impact (<100ms)
• Highly Configurable - Fine-tune every aspect of security
• Fail-Safe Design - Graceful degradation when components fail

📖 Documentation

Configuration Presets

Choose from pre-configured security levels:

from fastapi_fortify import SecurityMiddleware
from fastapi_guard.config.presets import ProductionConfig, HighSecurityConfig

# Production configuration
app.add_middleware(SecurityMiddleware, config=ProductionConfig())

# Maximum security configuration  
app.add_middleware(SecurityMiddleware, config=HighSecurityConfig())

Custom Configuration

from fastapi_fortify import SecurityMiddleware, SecurityConfig

config = SecurityConfig(
    # WAF Settings
    waf_enabled=True,
    waf_mode="strict",
    custom_waf_patterns=["custom_threat_pattern"],
    
    # Rate Limiting
    rate_limiting_enabled=True,
    rate_limit_requests=100,
    rate_limit_window=3600,
    
    # Bot Detection
    bot_detection_enabled=True,
    bot_detection_mode="balanced",
    allow_search_engines=True,
    
    # IP Blocklist
    ip_blocklist_enabled=True,
    ip_whitelist=["192.168.1.0/24"],
    block_private_networks=False,
    
    # Exclusions
    excluded_paths=["/health", "/metrics", "/docs"]
)

app.add_middleware(SecurityMiddleware, config=config)

Management API

Monitor and manage security in real-time:

from fastapi_fortify import SecurityMiddleware, create_security_api

# Add security middleware
middleware = SecurityMiddleware(app, config=config)

# Add management API
security_api = create_security_api(
    middleware_instance=middleware,
    api_key="your-secret-key"
)
app.include_router(security_api.router)

Access management endpoints:

• GET /security/health - Health check
• GET /security/status - Overall security status
• GET /security/threats/summary - Threat analysis
• POST /security/ip-blocklist/block - Block IP addresses
• GET /security/metrics - Security metrics

🔧 Advanced Usage

Custom Security Rules

from fastapi_guard.protection.waf import WAFProtection

# Create custom WAF with additional patterns
waf = WAFProtection(
    custom_patterns=[
        r"(?i)custom_malware_signature",
        r"(?i)company_specific_threat_pattern"
    ],
    exclusions=["/api/webhooks/*"]
)

# Add patterns at runtime
waf.add_custom_pattern(r"(?i)new_threat_pattern", "custom_threats")

Authentication Monitoring

from fastapi_guard.monitoring import create_auth_monitor

# Create auth monitor
auth_monitor = create_auth_monitor(
    security_level="strict",
    notifications=["webhook", "slack"],
    webhook_url="https://your-app.com/security-alerts"
)

# Process authentication events
await auth_monitor.process_login_attempt(
    email="[e-mail]",
    ip_address="192.168.1.100", 
    user_agent="Mozilla/5.0...",
    success=False  # Failed login
)
