## Security Features
|
||||
|
||||
### 1. Input Validation
|
||||
|
||||
**Purpose:** Prevent injection attacks (XSS, SQL injection, command injection) by validating and sanitizing all user input.
|
||||
|
||||
**Implementation Files:**
|
||||
- `backend/utils/inputValidator.js` - Core validation functions
|
||||
- `backend/middleware/inputValidation.js` - Reusable middleware
|
||||
- `frontend/src/utils/inputValidator.js` - Client-side validation
|
||||
- `frontend/src/components/ValidatedTextField.jsx` - Enhanced input component
|
||||
|
||||
**Key Features:**
|
||||
- ✅ Whitelist-based validation (more secure than blacklist)
|
||||
- ✅ SQL injection prevention (parameterized queries enforced)
|
||||
- ✅ XSS prevention (HTML entity encoding, script tag blocking)
|
||||
- ✅ Command injection prevention (shell character filtering)
|
||||
- ✅ Path traversal prevention (../ and absolute path blocking)
|
||||
- ✅ File upload validation (type, size, extension checks)
|
||||
- ✅ JSON validation (safe parsing, schema validation)
|
||||
- ✅ URL validation (protocol whitelist, localhost blocking)
|
||||
- ✅ Email validation (RFC 5322 compliant)
|
||||
- ✅ Username validation (alphanumeric + underscore/dash only)
|
||||
|
||||
**Protected Routes:**
|
||||
- `/api/playlists` - Playlist CRUD operations
|
||||

|
||||
- Visual indicators (checkmark/error icon)
|
||||
- Automatic HTML sanitization
|
||||
- Security notifications for blocked attacks
|
||||
|
||||
### 3. Content Security Policy (CSP)

|
||||
- ✅ Comprehensive directives (script, style, image, media, connect)
|
||||
- ✅ Automatic violation reporting
|
||||
- ✅ Violation analytics and statistics
|
||||
- ✅ Admin dashboard for monitoring
|
||||
- ✅ Nonce support for inline scripts

|
||||
- `GET /api/csp/stats` - Violation statistics and trends
|
||||
- `GET /api/csp/policy` - View current CSP configuration
|
||||
- `DELETE /api/csp/violations` - Clear old violation reports
|
||||
|
||||
**Policy Configuration:**
|
||||
```javascript
|
||||
{
|
||||
defaultSrc: ["'self'"],
|
||||
scriptSrc: ["'self'", "'unsafe-inline'", "'unsafe-eval'", "https://www.gstatic.com"],
|
||||
styleSrc: ["'self'", "'unsafe-inline'", "https://fonts.googleapis.com"],

objectSrc: ["'none'"],
|
||||
frameAncestors: ["'self'"],
|
||||
upgradeInsecureRequests: production only
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Session Management
|
||||
|
||||
**Purpose:** Prevent session fixation, session hijacking, and unauthorized access through proper session handling and timeout enforcement.

||||
- ✅ HTTP-only cookies (prevents XSS access to tokens)
|
||||
- ✅ Secure cookie flag (HTTPS-only in production)
|
||||
| **XSS (Stored)** | Input sanitization + HTML encoding | ✅ `sanitizeString()` removes script tags |
|
||||

|
||||
- ✅ Session metadata tracking (IP, user agent, timestamps)
|
||||
- ✅ Automatic session cleanup (hourly job)
|
||||
- ✅ User-facing session management UI
|
||||
- ✅ Admin session monitoring and control
|
||||
|
||||
**Session API Endpoints:**
|
||||
|
||||
**User Endpoints:**
|
||||
- `GET /api/sessions/my-sessions` - View active sessions
|
||||
- `DELETE /api/sessions/:sessionId` - Terminate specific session
|
||||
- `POST /api/sessions/terminate-all-others` - Bulk terminate
|
||||
- `POST /api/auth/logout` - Logout with session cleanup
|
||||
|
||||
**Admin Endpoints:**

||||
- `GET /api/sessions/all` - View all user sessions
|
||||
- `GET /api/sessions/stats` - Session statistics
|
||||
- `POST /api/sessions/force-logout/:userId` - Force user logout
|
||||
|
||||
**Cookie Security Configuration:**
|
||||
```javascript
|
||||
{
|
||||
httpOnly: true, // JavaScript cannot access
|
||||
secure: true, // HTTPS only (production)
|
||||
sameSite: 'strict', // No cross-site requests
|
||||
maxAge: 7 days // Cookie expiration
|
||||
}
|
||||
```
|
||||
|
||||
**Session Timeout Policy:**
|
||||
```javascript
|
||||
{
|
||||
maxConcurrentSessions: 3, // Per user limit
|
||||
absoluteTimeout: 24, // Hours until forced logout
|
||||
idleTimeout: 2, // Hours of inactivity allowed
|
||||
refreshTokenRotation: true // Future enhancement
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
# ✅ All files OK
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
### Manual Testing Checklist
|
||||
|
||||
**Input Validation:**
|
||||
- [ ] Try XSS payload in playlist name: `<script>alert('xss')</script>`
|
||||
- [ ] Try SQL injection in username: `' OR '1'='1`
|
||||
- [ ] Try path traversal in file name: `../../../etc/passwd`
|
||||
- [ ] Upload invalid file types
|
||||
- [ ] Test maximum length limits
|
||||
- [ ] Verify client-side validation feedback
|
||||
|
||||
**Session Management:**
|
||||
- [ ] Login and verify cookie is set with correct attributes
|
||||
- [ ] Wait 2+ hours and verify idle timeout
|
||||
- [ ] View active sessions UI
|
||||
- [ ] Terminate a session from another device
|
||||
- [ ] Bulk terminate all sessions
|
||||
- [ ] Admin: force logout another user
|
||||
- [ ] Verify logout clears cookie
|
||||
- [ ] Test concurrent session limit (try 4+ sessions)
|
||||
|
||||
### Automated Testing
|
||||
|
||||
**Backend Tests:**
|
||||
```bash
|
||||
# Test input validation
|
||||
npm test -- --grep "input validation"
|
||||
|
||||
# Test session management
|
||||
npm test -- --grep "session"
|
||||
|
||||
# Test authentication
|
||||
npm test -- --grep "auth"
|
||||
```
|
||||
|
||||
**Frontend Tests:**
|
||||
```bash
|
||||
# Test validation components
|
||||
npm test -- ValidatedTextField
|
||||
npm test -- SecurityNotificationProvider
|
||||
npm test -- SessionManagement
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Input Validation
|
||||
- **Overhead:** ~1-5ms per request (validation + sanitization)
|
||||
- **Impact:** Negligible - validation is synchronous and fast
|
||||
- **Optimization:** Validation results not cached (security vs performance trade-off)
|
||||
|
||||
### Session Management
|
||||
- **Overhead:** ~10-20ms per request (DB session lookup + update)
|
||||
- **Impact:** Low - single SELECT and UPDATE per authenticated request
|
||||
- **Optimization:** Database indexes on `session_token` and `user_id`
|
||||
|
||||
### Session Cleanup Job
|
||||
- **Frequency:** Every 60 minutes
|
||||
- **Duration:** ~100-500ms (depends on session count)
|
||||
- **Impact:** Background job, no user-facing impact
|
||||
|
||||
## Security Audit Logging
|
||||
|
||||
All security events are logged to `security_audit_log` table:
|
||||
|
||||
**Event Types:**
|
||||
- `login`, `logout`, `registration`
|
||||
- `password_change`, `password_expired`
|
||||
- `2fa_enabled`, `2fa_disabled`, `2fa_verification`
|
||||
- `session_terminated`, `session_force_logout`
|
||||
- `account_locked`, `account_unlocked`
|
||||
- `validation_failed`, `xss_blocked`, `sql_injection_blocked`
|
||||
|
||||
**Log Retention:**
|
||||
- Default: 90 days
|
||||
- Configurable in `passwordPolicy.js`
|
||||
- Admin can export logs via UI
|
||||
|
||||
## Production Deployment Checklist
|
||||
|
||||

## Known Limitations & Future Enhancements
|
||||
|
||||
### Current Limitations
|
||||
1. **No Refresh Token Rotation** - Currently uses long-lived JWTs
|
||||
2. **No Device Fingerprinting** - Basic user agent tracking only
|
||||
3. **No Geographic Restrictions** - Sessions allowed from any location
|
||||
4. **No Rate Limiting on Session API** - Could add separate limiter
|
||||
|
||||
### Planned Enhancements
|
||||
1. **Refresh Token Implementation**
|
||||
- Short-lived access tokens (15 minutes)
|
||||
- Long-lived refresh tokens (7 days)
|
||||
- Automatic rotation on use
|
||||
|
||||
2. **Enhanced Device Fingerprinting**
|
||||
- Canvas fingerprinting
|
||||
- WebGL fingerprinting
|
||||
- Screen resolution tracking
|
||||
- Timezone detection
|
||||
|
||||
3. **Geographic Session Restrictions**
|
||||
- IP geolocation tracking
|
||||
- Alert on new country login
|
||||
- Optional country whitelist
|
||||
|
||||
4. **Session Analytics Dashboard**
|
||||
- Session duration trends
|
||||
- Device distribution charts
|
||||
- Peak usage times
|
||||
- Suspicious activity detection
|
||||
|
||||
## Support & Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
**Issue:** Sessions expire too quickly
|
||||
**Solution:** Increase `SESSION_POLICY.idleTimeout` in `passwordPolicy.js`
|
||||
|
||||
**Issue:** Too many active sessions
|
||||
**Solution:** Decrease `SESSION_POLICY.maxConcurrentSessions`
|
||||
|
||||
**Issue:** Cookies not working
|
||||
**Solution:** Check `NODE_ENV=production` and HTTPS is enabled
|
||||
|
||||
**Issue:** Validation too strict
|
||||
**Solution:** Review and adjust validation rules in `inputValidator.js`
|
||||
|
||||
**Issue:** Rate limit blocking legitimate users
|
||||
**Solution:** Increase rate limit thresholds or adjust window
|
||||
|
||||
### Debug Mode
|
||||
|
||||
Enable debug logging:
|
||||
```javascript
|
||||
// backend/utils/logger.js
|
||||
const logger = winston.createLogger({
|
||||
level: 'debug', // Change from 'info' to 'debug'
|
||||
// ...
|
||||
});
|
||||
```
|
||||
