||||
**Current Status**: Basic security implemented, several gaps identified
|
||||
**Target**: Production-ready security standards
|
||||
**Priority**: 🟡 Medium - Important for production deployment

||||
|
||||
## 🔐 Authentication Security
|
||||
|
||||
### Rate Limiting Implementation
|
||||
|
||||
**Impact**: Prevent brute force attacks
|
||||
**Current**: No rate limiting on auth endpoints
|
||||
**Priority**: 🟡 Medium
|
||||
|
||||
- [ ] **Install rate limiting middleware (`express-rate-limit` or similar)**
|
||||
- [ ] **Add rate limiting to `/api/auth/login` (5 attempts/5min)**
|
||||
- [ ] **Add rate limiting to `/api/auth/register` (3 attempts/hour)**
|
||||
- [ ] **Add rate limiting to `/api/auth/refresh` (10 attempts/5min)**
|
||||
- [ ] **Implement progressive delays for repeated failures**
|
||||
- [ ] **Add IP-based and user-based rate limiting**
|
||||
|
||||
```typescript
|
||||
// ADD TO lib/rate-limit.ts:
|
||||
import rateLimit from 'express-rate-limit'
|
||||
|
||||
export const authRateLimit = rateLimit({
|
||||
windowMs: 5 * 60 * 1000, // 5 minutes
|
||||
max: 5, // 5 attempts per window
|
||||
message: { error: 'Too many login attempts, try again later' },
|
||||
standardHeaders: true,
|
||||
legacyHeaders: false,
|
||||
})
|
||||
```
|
||||
|
||||
### Password Security Enhancement
|
||||

||||
const passwordSchema = z
|
||||
.string()
|
||||
.min(8, 'Password must be at least 8 characters')
|
||||
.regex(/[A-Z]/, 'Password must contain at least one uppercase letter')
|
||||
.regex(/[0-9]/, 'Password must contain at least one number')
|
||||
.regex(/[^A-Za-z0-9]/, 'Password must contain at least one special character')
|
||||
```
|
||||
|
||||
### Email Verification System
|
||||
