## 🔧 Optimization Recommendations
|
||||
|
||||
### 1. **Immediate Optimizations**
|
||||
|
||||
```typescript
|
||||
// Add Redis caching for partnership validation
|
||||
class OptimizedParticipantIsolation {
|
||||
private cache: Redis;
|
||||
|
||||
async validatePartnerAccess(orgId: string, partnerId: string) {
|
||||
const cacheKey = `partnership:${orgId}:${partnerId}`;
|
||||
const cached = await this.cache.get(cacheKey);
|
||||
|
||||
if (cached) return JSON.parse(cached);
|
||||
|
||||
const result = await this.prisma.partnership.findFirst({...});
|
||||
await this.cache.setex(cacheKey, 3600, JSON.stringify(result));
|
||||
|
||||
return result;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2. **Database Optimizations**
|
||||
|
||||
```sql
|
||||
-- Add composite indexes for common queries
|
||||
CREATE INDEX idx_partnership_lookup ON partnerships(organization_id, partner_id, active);
|
||||
CREATE INDEX idx_audit_user_time ON commercial_data_audits(user_id, created_at DESC);
|
||||
CREATE INDEX idx_supply_order_org ON supply_orders(organization_id, status);
|
||||
```
|
||||
|
||||
### 3. **Filtering Optimizations**
|
||||
|
||||
```typescript
|
||||
// Implement lazy filtering for large objects
|
||||
class LazySupplyDataFilter {
|
||||
static filterSupplyOrder(order: any, context: SecurityContext) {
|
||||
// Only filter requested fields
|
||||
return new Proxy(order, {
|
||||
get(target, prop) {
|
||||
if (shouldFilterField(prop, context)) {
|
||||
return undefined
|
||||
}
|
||||
return target[prop]
|
||||
},
|
||||
})
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. **Batch Processing**
|
||||
|
||||
```typescript
|
||||
// Batch audit log insertions
|
||||
class BatchAuditLogger {
|
||||
private queue: AuditLog[] = []
|
||||
|
||||
async logAccess(params: AuditParams) {
|
||||
this.queue.push(params)
|
||||
|
||||
if (this.queue.length >= 100) {
|
||||
await this.flush()
|
||||
}
|
||||
}
|
||||
|
||||
private async flush() {
|
||||
await this.prisma.commercialDataAudit.createMany({
|
||||
data: this.queue,
|
||||
})
|
||||
this.queue = []
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## 🛡️ Security Vulnerabilities
|
||||
|
||||
### Identified Issues
|
||||
|
||||
1. **Rate Limiting** (Medium)
|
||||
- No built-in rate limiting for API calls
|
||||
- Recommendation: Implement Redis-based rate limiting
|
||||
|
||||
2. **Session Management** (Low)
|
||||
- No session timeout configuration
|
||||
- Recommendation: Add configurable session timeouts
|
||||
|
||||
3. **Input Validation** (Low)
|
||||
- Limited input sanitization
|
||||
- Recommendation: Add comprehensive input validation
|
||||
|
||||
### Mitigation Plan
|
||||
|
||||
```typescript
|
||||
// Add rate limiting middleware
|
||||
const rateLimiter = rateLimit({
|
||||
windowMs: 15 * 60 * 1000, // 15 minutes
|
||||
max: 100, // limit each IP to 100 requests per windowMs
|
||||
keyGenerator: (req) => `${req.ip}:${req.user?.id}`,
|
||||
})
|
||||
|
||||
// Add input validation
|
||||
const validateSupplyOrderInput = z.object({
|
||||
id: z.string().uuid(),
|
||||
status: z.enum(['PENDING', 'APPROVED', 'REJECTED']),
|
||||
items: z.array(
|
||||
z.object({
|
||||
productId: z.string().uuid(),
|
||||
quantity: z.number().positive(),
|
||||
}),
|
||||
),
|
||||
})
|
||||
```
|
||||
|
||||
