## 🔐 Security Architecture

### Multi-Layer Security

1. **Client-Side Sanitization**
   - Input validation (length, patterns)
   - Output sanitization (DOMPurify)
   - XSS detection

2. **Backend Proxy**
   - API key hidden from client
   - Rate limiting (10 req/min for AI)
   - Input validation
   - Security headers (Helmet.js)

3. **Data Protection**
   - Encrypted localStorage
   - Session expiration
   - Secure cookie handling

4. **Network Security**
   - CORS configuration
   - CSP headers
   - HTTPS enforcement (in production)

### Risk Mitigation

| Risk | Original | Mitigated |
|------|----------|-----------|
| Prompt Injection | CRITICAL | ✅ Controlled |
| API Key Exposure | CRITICAL | ✅ Controlled |
| XSS Attacks | CRITICAL | ✅ Controlled |
| DoS Attacks | CRITICAL | ✅ Controlled |
| Session Hijacking | HIGH | ✅ Controlled |
| Data Exposure | MEDIUM | ✅ Controlled |

**Overall Risk Level**: CONTROLLED (down from CRITICAL)

## 🚀 How to Use

### Option 1: Frontend Only (Demo Mode)
1. Open `index.html` in a web browser
2. Type `help` to see commands
3. Try commands like `echo hello`, `date`, `theme monokai`
4. AI commands work in demo mode

### Option 2: Full Setup with Backend
1. Install Node.js dependencies:
   ```bash
   cd ai-cli-webapp
   npm install
   ```

2. Create `.env` file:
   ```bash
   cp .env.example .env
   # Edit .env and add your OpenAI API key
   ```

3. Start backend server:
   ```bash
   npm start
   ```

4. Open `index.html` in browser
5. AI features now connect to real OpenAI API
