# Frontend Security Implementation Summary
|
|
|
|
## ✅ Completed Security Enhancements
|
|
|
|
### 1. Package Security
|
|
- ✅ **No postinstall scripts** - Verified package.json is clean
|
|
- ✅ **.npmrc configured** - Security settings enabled
|
|
- ✅ **Security scripts added** - `security:audit`, `security:fix`, `security:check`, `security:scan`
|
|
- ✅ **Vulnerabilities fixed** - All npm audit vulnerabilities resolved
|
|
|
|
### 2. XSS Prevention
|
|
- ✅ **DOMPurify installed** - `isomorphic-dompurify` for server/client-side sanitization
|
|
- ✅ **HTML sanitization implemented** - All `dangerouslySetInnerHTML` now uses `sanitizeHTML()`
|
|
- ✅ **Fixed components:**
|
|
- `components/pages/blog/BlogSingle.tsx`
|
|
- `components/pages/case-study/CaseSingle.tsx`
|
|
- `components/pages/support/KnowledgeBaseArticleModal.tsx`
|
|
- `app/policy/page.tsx`
|
|
|
|
### 3. Content Security Policy (CSP)
|
|
- ✅ **Removed 'unsafe-eval'** from production CSP
|
|
- ✅ **Removed localhost** from production CSP
|
|
- ✅ **Added security directives** - `object-src 'none'`, `upgrade-insecure-requests`
|
|
- ✅ **Environment-specific CSP** - Different policies for dev/prod
|
|
|
|
### 4. IP Whitelisting & Access Control
|
|
- ✅ **Security middleware** - `middleware.ts` implemented
|
|
- ✅ **IP whitelisting utility** - `lib/security/ipWhitelist.ts`
|
|
- ✅ **Protected paths** - `/api/admin`, `/api/scripts`, `/api/deploy`
|
|
- ✅ **Request validation** - Blocks non-whitelisted IPs on protected paths
|
|
|
|
### 5. Request Security
|
|
- ✅ **Malicious user agent blocking** - Known bots/scrapers blocked
|
|
- ✅ **Suspicious pattern detection** - XSS/SQL injection patterns blocked
|
|
- ✅ **IP blocking** - Configurable blocked IPs list
|
|
- ✅ **Security logging** - All security events logged
|
|
|
|
### 6. Security Configuration
|
|
- ✅ **Centralized config** - `lib/security/config.ts`
|
|
- ✅ **Security headers** - All critical headers configured
|
|
- ✅ **Rate limiting config** - Ready for implementation
|
|
- ✅ **File upload restrictions** - Config defined
|
|
|
|
### 7. Security Scanning
|
|
- ✅ **Automated scan script** - `scripts/security-scan.sh`
|
|
- ✅ **Comprehensive checks:**
|
|
- Postinstall scripts
|
|
- Suspicious code patterns
|
|
- Dangerous code patterns
|
|
- Exposed secrets
|
|
- npm audit
|
|
- Outdated packages
|
|
- .env file security
|
|
- Malware patterns
|
|
|
|
### 8. Documentation
|
|
- ✅ **Security audit report** - `SECURITY_AUDIT.md`
|
|
- ✅ **Security module README** - `lib/security/README.md`
|
|
- ✅ **Implementation summary** - This document
|
|

|
## 🚀 Usage
|
|
|
|
### Run Security Scan
|
|
```bash
|
|
cd frontEnd
|
|
./scripts/security-scan.sh
|
|
```
|
|
|
|
### Run Security Audit
|
|
```bash
|
|
npm run security:audit
|
|
npm run security:fix
|
|
npm run security:check
|
|
npm run security:scan
|
|
```
|
|
|
|
### Configure IP Whitelisting
|
|
Edit `lib/security/config.ts`:
|
|
```typescript
|
|
export const ALLOWED_IPS = [
|
|
'127.0.0.1',
|
|
'::1',
|
|
'your-trusted-ip',
|
|
];
|
|
```
|
|
|
|
### Sanitize HTML Content
|
|
```typescript
|
|
import { sanitizeHTML } from '@/lib/security/sanitize';
|
|
|
|
const safeHTML = sanitizeHTML(userContent);
|
|
```
|
|
|
|
## 📊 Security Status
