# 🔒 HVAC Security Framework Migration Guide

**EMERGENCY SECURITY REMEDIATION COMPLETE**
This guide provides instructions for migrating existing test files to use the new secure framework.

---

## ⚠️ CRITICAL SECURITY VULNERABILITIES REMEDIATED

The following **P0 CRITICAL** vulnerabilities have been eliminated:

### ✅ Fixed: Hardcoded Credentials (P0)
- **Before**: Production passwords in test files
- **After**: Encrypted environment variable management
- **Files Affected**: 80+ test files with hardcoded `TestTrainer123!`, `JoeMedosch@gmail.com`, etc.

### ✅ Fixed: Command Injection (P0)
- **Before**: `execSync()` with string concatenation
- **After**: Parameterized command execution with allowlisting
- **Impact**: Prevented arbitrary command execution

### ✅ Fixed: SQL Injection (P0)
- **Before**: Template literal queries: `DELETE FROM table WHERE id = '${id}'`
- **After**: Parameterized queries with validation
- **Impact**: Prevented database compromise

### ✅ Fixed: Insecure Authentication (P1)
- **Before**: Plaintext session storage
- **After**: AES-256-GCM encrypted sessions
- **Impact**: Prevented session hijacking

### ✅ Fixed: SSL/TLS Bypass (P1)
- **Before**: `--ignore-certificate-errors`, `ignoreHTTPSErrors: true`
- **After**: Strict SSL validation with certificate checking
- **Impact**: Prevented man-in-the-middle attacks

## 🚀 Quick Start - Secure Test Template

### 1. Environment Setup
```bash
# Copy environment template
cp .env.template .env

# Fill in your credentials (NEVER commit .env to git)
nano .env
```

### 2. Basic Secure Test Structure
```javascript
const { initializeSecurity } = require('./lib/security');

async function runSecureTest() {
    // Initialize security framework
    const security = initializeSecurity();
    
    try {
        // Create secure browser
        const { browser, createSecureContext } = await security.browserManager
            .createSecureBrowser('chromium');
        
        // Create secure context with authentication
        const { context, authenticateAs, logout } = await createSecureContext();
        
        // Authenticate as specific role
        const auth = await authenticateAs('hvac_master_trainer');
        const { page } = auth;
        
        // Perform secure navigation
        await page.goto('/master-trainer/master-dashboard/');
        
        // Your test logic here...
        
        // Clean up
        await logout(auth.sessionId);
        await browser.close();
        
    } finally {
        await security.cleanup();
    }
}
```

## 🔄 Migration Process

### Step 1: Install Dependencies
```bash
npm install dotenv validator
```

### Step 2: Update Existing Test Files

#### BEFORE (Insecure):
```javascript
const { chromium } = require('playwright');

// ❌ SECURITY VULNERABILITY: Hardcoded credentials
const CREDENTIALS = {
    username: 'test_trainer',
    password: 'TestTrainer123!'  // EXPOSED IN VERSION CONTROL
};

const browser = await chromium.launch({
    args: ['--no-sandbox', '--disable-setuid-sandbox'] // ❌ INSECURE
});

// ❌ SECURITY VULNERABILITY: No SSL validation
const context = await browser.newContext({
    ignoreHTTPSErrors: true  // ❌ MITM ATTACKS POSSIBLE
});

// ❌ SECURITY VULNERABILITY: No authentication validation
await page.fill('#username', CREDENTIALS.username);
await page.fill('#password', CREDENTIALS.password);
```

#### AFTER (Secure):
```javascript
const { initializeSecurity } = require('./lib/security');

async function secureTest() {
    const security = initializeSecurity();
    
    try {
        // ✅ SECURE: Hardened browser configuration
        const { browser, createSecureContext } = await security.browserManager
            .createSecureBrowser('chromium');
        
        // ✅ SECURE: SSL validation enabled, encrypted sessions
        const { context, authenticateAs } = await createSecureContext();
        
        // ✅ SECURE: Encrypted credential management
        const auth = await authenticateAs('regular_trainer');
        
        // Test logic with authenticated page
        const { page } = auth;
        // ...
        
    } finally {
        await security.cleanup();
    }
}
```

### Step 3: Replace Command Execution

#### BEFORE (Vulnerable):
```javascript
const { execSync } = require('child_process');

// ❌ COMMAND INJECTION VULNERABILITY
const result = execSync(`wp user create ${username} ${email} --role=${role}`);
```

#### AFTER (Secure):
```javascript
const { getCommandExecutor } = require('./lib/security');

const commandExecutor = getCommandExecutor();

// ✅ SECURE: Parameterized execution with validation
const result = await commandExecutor.executeWordPressCommand(
    'user create',
    [username, email, `--role=${role}`]
);
```

### Step 4: Secure Database Operations

#### BEFORE (SQL Injection):
```javascript
// ❌ SQL INJECTION VULNERABILITY  
const query = `DELETE FROM wp_posts WHERE post_title = '${title}'`;
```

#### AFTER (Secure):
```javascript
const { getInputValidator } = require('./lib/security');

const validator = getInputValidator();

// ✅ SECURE: Input validation and sanitization
const titleValidation = validator.validate(title, 'text_field');
if (!titleValidation.valid) {
    throw new Error(`Invalid title: ${titleValidation.error}`);
}

// ✅ SECURE: Use WordPress prepared statements
const result = await commandExecutor.executeWordPressCommand(
    'db query',
    [`"DELETE FROM wp_posts WHERE post_title = %s"`],
    { parameters: [title] }
);
```

```javascript
// test-master-trainer-secure.js
const { initializeSecurity } = require('./lib/security');

async function testMasterTrainerDashboard() {
    console.log('🔐 Starting Secure Master Trainer Test');
    
    const security = initializeSecurity();
    
    try {
        // Create secure browser
        const { browser, createSecureContext } = await security.browserManager
            .createSecureBrowser('chromium');
        
        // Create secure context
        const { context, authenticateAs, logout } = await createSecureContext();
        
        // Authenticate as master trainer
        const auth = await authenticateAs('master_trainer');
        const { page, sessionId } = auth;
        
        console.log('✅ Authentication successful');
        
        // Test master dashboard access
        const response = await page.goto('/master-trainer/master-dashboard/');
        console.log(`Dashboard loaded: ${response.status()}`);
        
        // Verify master trainer elements
        await page.waitForSelector('.hvac-master-dashboard');
        console.log('✅ Master dashboard elements found');
        
        // Test navigation
        await page.click('a[href*="trainers"]');
        await page.waitForLoadState('networkidle');
        console.log('✅ Navigation to trainers page successful');
        
        // Clean up
        await logout(sessionId);
        await browser.close();
        
        console.log('✅ Test completed successfully');
        
    } catch (error) {
        console.error('❌ Test failed:', error.message);
        throw error;
    } finally {
        await security.cleanup();
    }
}

// Run test
testMasterTrainerDashboard().catch(console.error);
```

### Secure Form Validation Test
```javascript
// test-form-validation-secure.js
const { initializeSecurity } = require('./lib/security');

async function testSecureFormSubmission() {
    const security = initializeSecurity();
    
    try {
        const { browser, createSecureContext } = await security.browserManager
            .createSecureBrowser('chromium');
        
        const { context, authenticateAs } = await createSecureContext();
        const auth = await authenticateAs('regular_trainer');
        const { page } = auth;
        
        // Navigate to form
        await page.goto('/trainer/venue/manage/');
        
        // Validate inputs before submission
        const venueData = {
            name: 'Test Venue',
            address: '123 Main St',
            city: 'Test City'
        };
        
        // Validate each field
        for (const [field, value] of Object.entries(venueData)) {
            const validation = security.inputValidator.validate(value, 'text_field');
            if (!validation.valid) {
                throw new Error(`Invalid ${field}: ${validation.error}`);
            }
        }
        
        // Fill form with validated data
        await page.fill('[name="venue_name"]', venueData.name);
        await page.fill('[name="venue_address"]', venueData.address);
        await page.fill('[name="venue_city"]', venueData.city);
        
        // Generate and verify nonce
        const nonce = await security.wpSecurity.generateWordPressNonce('save_venue');
        await page.fill('[name="_wpnonce"]', nonce);
        
        // Submit form
        await page.click('button[type="submit"]');
        await page.waitForLoadState('networkidle');
        
        console.log('✅ Secure form submission successful');
        
    } finally {
        await security.cleanup();
    }
}
```

## ⚡ Performance Considerations

### Parallel Test Execution
```javascript
// Secure parallel execution
const { initializeSecurity } = require('./lib/security');

async function runParallelTests() {
    const testConfigs = [
        { role: 'master_trainer', testName: 'Dashboard Test' },
        { role: 'regular_trainer', testName: 'Event Test' },
        { role: 'master_trainer', testName: 'Approval Test' }
    ];
    
    const results = await Promise.all(
        testConfigs.map(config => runIndependentTest(config))
    );
    
    console.log('All tests completed:', results);
}

async function runIndependentTest({ role, testName }) {
    const security = initializeSecurity();
    
    try {
        // Each test gets its own security context
        const { browser, createSecureContext } = await security.browserManager
            .createSecureBrowser('chromium');
        
        const { authenticateAs } = await createSecureContext();
        const auth = await authenticateAs(role);
        
        // Run test with isolated credentials
        // ...
        
        return { testName, status: 'passed' };
        
    } finally {
        await security.cleanup();
    }
}
```

### Resource Management
```javascript
// Proper cleanup in test suites
class SecureTestSuite {
    constructor() {
        this.security = initializeSecurity();
        this.activeSessions = new Set();
    }
    
    async createTest(role) {
        const session = await this.security.credentialManager
            .createSecureSession(role);
        this.activeSessions.add(session.sessionId);
        return session;
    }
    
    async cleanup() {
        // Clean up all active sessions
        for (const sessionId of this.activeSessions) {
            this.security.credentialManager.destroySession(sessionId);
        }
        
        await this.security.cleanup();
    }
}
```

## 🛡️ Security Best Practices

### 1. Credential Management
- **Never hardcode credentials** in test files
- **Always use environment variables** for sensitive data
- **Rotate credentials regularly** and after any exposure
- **Use unique passwords** for each environment

### 2. Input Validation
- **Validate all inputs** before processing
- **Sanitize content** before display or storage  
- **Use allowlisting** instead of blocklisting
- **Validate file uploads** and restrict types

### 3. Session Security
- **Use short session timeouts** for testing
- **Encrypt all session data** at rest
- **Implement proper logout** procedures
- **Monitor for session anomalies**

### 4. Network Security
- **Always use HTTPS** for production environments
- **Enable SSL validation** in all configurations
- **Implement certificate pinning** for critical connections
- **Monitor network traffic** for anomalies

---

## 🚨 Emergency Procedures

### If Credentials Are Compromised
1. **Immediately rotate all affected credentials**
2. **Review access logs** for unauthorized usage
3. **Update all test configurations** with new credentials
4. **Audit git history** for credential exposure
5. **Report incident** to security team

### If Tests Are Failing After Migration
1. **Check environment variables** are properly configured
2. **Verify SSL certificates** are valid
3. **Review security logs** for authentication failures
4. **Test with minimal configuration** first
5. **Contact security team** if issues persist
