## 🛡️ Core Features

### Runtime Application Self-Protection (RASP)

1. **Injection Detection**
   - SQL Injection (30+ patterns)
   - NoSQL Injection (MongoDB operators)
   - Command Injection (shell metacharacters)
   - Path Traversal (directory navigation)
   - XXE (XML External Entity)
   - SSRF (Server-Side Request Forgery)

2. **XSS Protection**
   - Direct XSS pattern matching
   - Encoded payload detection
   - HTML entity decoding
   - URL decoding
   - Unicode/Hex decoding
   - Output sanitization

3. **CSRF Protection**
   - Token-based validation
   - Origin header checking
   - Referer validation
   - Session-based tokens
   - Automatic token expiration

4. **Anomaly Detection**
   - Rate limiting (configurable)
   - Request pattern analysis
   - Suspicious user-agent detection
   - Authentication bypass detection
   - Large request body detection
   - Sequential scanning detection

### API Fuzzing Engine

1. **Smart Parameter Mutation**
   - Type-aware payload generation
   - Automatic parameter discovery
   - Context-sensitive mutations

2. **Attack Vector Testing**
   - SQL/NoSQL injection
   - XSS (10+ variants)
   - Command injection
   - Path traversal
   - SSRF
   - XXE
   - Buffer overflow
   - Integer overflow

3. **Authentication Testing**
   - Auth bypass attempts
   - Token manipulation
   - Session hijacking
   - Credential stuffing

4. **GraphQL Security**
   - Introspection query detection
   - Schema exposure testing
   - Query depth analysis

5. **Rate Limit Testing**
   - Burst request simulation
   - Distributed attack patterns

## 🚀 Usage Examples

### Quick Start (3 lines)

```javascript
const Aimless = require('aimless-security');
const aimless = new Aimless({ rasp: { enabled: true } });
app.use(aimless.middleware());
```

### API Fuzzing

```javascript
const result = await aimless.fuzz({
  url: 'https://api.example.com/users',
  method: 'POST',
  body: { username: 'test', password: 'test123' }
});

console.log(`Found ${result.vulnerabilities.length} vulnerabilities`);
```

### CSRF Protection

```javascript
app.use(aimless.csrf());
app.get('/form', (req, res) => {
  res.send(`<input type="hidden" value="${res.locals.csrfToken}">`);
});
```

## 🎯 Use Cases

1. **Production Security**: Real-time protection for production APIs
2. **Development**: Early vulnerability detection during development
3. **Security Testing**: Automated security testing in CI/CD
4. **Compliance**: Meet security compliance requirements
5. **Monitoring**: Security event logging and alerting

## 📈 Performance

- **Overhead**: < 1ms per request (typical)
- **Memory**: ~10MB baseline
- **Scalability**: Handles 10,000+ req/s
- **Latency**: Minimal impact on API response times

## 🔒 Security Model

1. **Defense in Depth**: Multiple layers of protection
2. **Zero Trust**: Every request is validated
3. **Fail Secure**: Errors result in blocking, not bypass
4. **Minimal False Positives**: Tuned patterns for accuracy
5. **Configurable**: Adjust sensitivity to your needs

## 📝 Getting Started

1. **Install**: `npm install aimless-security`
2. **Configure**: Set up RASP and fuzzing options
3. **Integrate**: Add middleware to your Express app
4. **Test**: Run fuzzing tests on your APIs
5. **Monitor**: Review logs and adjust configuration

## 🛠️ Development
