# Security Fortress Command

Automatic and proactive threat protection using advanced AI to create an impenetrable security fortress.

## Description

The `/security-fortress` command establishes a complete security shield around your application:

- **Real-time vulnerability analysis**
- **Automatic protection** against common attacks
- **Automatic configuration hardening**
- **Proactive threat monitoring**
- **Automatic compliance** with security standards
- **Automated incident response**
- **Automatically applied security patches**
- **Continuous penetration testing**
- **Complete and automatic audit trails**

## Usage

```
/security-fortress [directory] [--scan] [--harden] [--monitor] [--compliance]
```

### Parameters

- `directory`: specific directory to secure
- `--scan`: Scan types (static, dynamic, dependency, secrets, compliance)
- `--harden`: Hardening level (basic, advanced, paranoid)
- `--monitor`: Real-time monitoring (threats, intrusion, anomaly)
- `--compliance`: Compliance standards (owasp, sox, gdpr, hipaa, pci)
- `--auto-fix`: Apply fixes automatically
- `--penetration-test`: Execute penetration testing
- `--audit-trail`: Generate complete audit trail

### Examples

## Automatic Protections

### 🛡️ Input Validation & Sanitization
```javascript
// ❌ BEFORE - Vulnerable to attacks
const UserController = {
  async createUser(req, res) {
    const { name, email, bio } = req.body;
    
    // SQL Injection vulnerable
    const query = `INSERT INTO users (name, email, bio) VALUES ('${name}', '${email}', '${bio}')`;
    await db.query(query);
    
    // XSS vulnerable - direct render
    res.json({ message: `User ${name} created successfully!` });
  },
  
  async updateProfile(req, res) {
    const userId = req.params.id; // No validation
    const data = req.body; // No sanitization
    
    await User.update(data, { where: { id: userId } });
    res.json({ success: true });
  }
};

// ✅ AFTER - Automatically Protected
import { body, param, validationResult } from 'express-validator';
import DOMPurify from 'dompurify';
import rateLimit from 'express-rate-limit';

const UserController = {
  // Automatically added Rate limiting
  createUserLimiter: rateLimit({
    windowMs: 15 * 60 * 1000, // 15 minutes
    max: 5, // 5 requests per window
    message: 'Too many user creation attempts'
  }),
  
  // Automatically added Validation middleware
  validateCreateUser: [
    body('name')
      .isLength({ min: 2, max: 50 })
      .matches(/^[a-zA-Z\s]+$/)
      .withMessage('Name must contain only letters and spaces'),
    body('email')
      .isEmail()
      .normalizeEmail()
      .withMessage('Valid email required'),
    body('bio')
      .optional()
      .isLength({ max: 500 })
      .withMessage('Bio must be less than 500 characters')
  ],
  
  async createUser(req, res) {
    // Input validation check
    const errors = validationResult(req);
    if (!errors.isEmpty()) {
      return res.status(400).json({ 
        errors: errors.array(),
        timestamp: new Date().toISOString(),
        requestId: req.id
      });
    }
    
    const { name, email, bio } = req.body;
    
    // Automatically added Sanitization
    const sanitizedData = {
      name: DOMPurify.sanitize(name.trim()),
      email: email.toLowerCase().trim(),
      bio: bio ? DOMPurify.sanitize(bio.trim()) : null
    };
    
    try {
      // Automatically applied Prepared statements
      const user = await User.create(sanitizedData);
      
      // Automatically added Audit log
      await AuditLog.create({
        action: 'USER_CREATED',
        userId: user.id,
        metadata: { email: sanitizedData.email },
        ipAddress: req.ip,
        userAgent: req.get('User-Agent'),
        timestamp: new Date()
      });
      
      // Response sanitization
      res.json({ 
        message: 'User created successfully',
        userId: user.id,
        timestamp: new Date().toISOString()
      });
    } catch (error) {
      // Error logging without sensitive information
      logger.error('User creation failed', {
        error: error.message,
        requestId: req.id,
        timestamp: new Date().toISOString()
      });
      
      res.status(500).json({ 
        message: 'Internal server error',
        requestId: req.id
      });
    }
  }
};
```

### 🔐 Authentication & Authorization
```javascript
// ❌ BEFORE - Weak Authentication
const auth = {

      const token = jwt.sign({ userId: user.id }, 'secret-key');
      res.json({ token });
    } else {

    }
  },
  
  authenticate(req, res, next) {
    const token = req.headers.authorization;
    const decoded = jwt.verify(token, 'secret-key');
    req.user = decoded;
    next();
  }
