---

## 2. Implemented Security Improvements

### 2.1 CSRF Protection (`/lib/csrf.ts`)

**Implementation:**
- Double-submit cookie pattern
- Token validation with 4-hour expiration
- Nonce tracking to prevent replay attacks
- Automatic token rotation

**Code Example:**
```typescript
// Generate CSRF token for session
const csrfToken = generateCSRFToken(sessionId, ipAddress);

// Verify on state-changing operations
const verification = verifyCSRFToken(token, sessionId, ipAddress);
```

**OWASP Reference:** [A01:2021 - Broken Access Control](https://owasp.org/Top10/A01_2021-Broken_Access_Control/)

### 2.2 Enhanced Session Management (`/lib/sessionManagement.ts`)

**Implementation:**
- Device fingerprinting
- Concurrent session limits (max 5)
- Activity-based timeout (30 min)
- Absolute timeout (24 hours)
- Suspicious activity detection

**Features:**
```typescript
// Create secure session with fingerprinting
const { session, token } = createSession(userId, ipAddress, userAgent);

// Track and validate session consistency
const { valid, reason } = verifySession(token, ipAddress, userAgent);
```

**OWASP Reference:** [A07:2021 - Identification and Authentication Failures](https://owasp.org/Top10/A07_2021-Identification_and_Authentication_Failures/)

### 2.3 Two-Factor Authentication (`/lib/twoFactorAuth.ts`)

**Implementation:**
- TOTP (RFC 6238) compliant
- QR code generation for authenticator apps
- Backup codes (10 codes)
- Brute force protection (5 attempts, 15 min lockout)

**Setup Flow:**
```typescript
// Generate TOTP secret
const { secret, qrCode, backupCodes } = generateTOTPSecret(userId);

// Enable after verification
const { success, backupCodes } = enableTOTP(userId, verificationCode);

// Verify during login
const { valid } = verifyTOTP(userId, code, ipAddress);
```

**OWASP Reference:** [A07:2021 - Identification and Authentication Failures](https://owasp.org/Top10/A07_2021-Identification_and_Authentication_Failures/)

### 2.4 API Versioning (`/lib/apiVersioning.ts`)

**Implementation:**
- Multiple version support (v1, v2, v3)
- Deprecation warnings
- Backward compatibility
- Version negotiation

**Usage:**
```typescript
// Extract version from request
const { version, source } = extractAPIVersion(request);

// Apply versioning middleware
return versionMiddleware(request, async (req, ver) => {
  const handler = getVersionedHandler(path, ver);
  return handler(req);
});
```

### 2.5 Request Signing (`/lib/requestSigning.ts`)

**Implementation:**
- HMAC-SHA256 signing
- API key management
- Nonce replay protection
- Timestamp validation (5 min window)

**Required for:**
- Purchase operations > $1000
- Admin actions
- Vote execution
- Security configuration changes

**Example:**
```typescript
// Sign sensitive request
const signed = signRequest(apiSecret, 'POST', '/api/purchase', body);

// Verify on server
const { valid, userId } = verifySignedRequest(headers, method, path, body);
```
