## 1. Sicherheitsarchitektur

### 1.1 Datenfluss & Netzwerk-Architektur

**Step 1: Analyse (Anthropic)**
Kundendaten → Anthropic Claude → Strategische Erkenntnisse

**Step 2: Visualisierung (ACG Slide Studio)**
Erkenntnisse → ACG Slide Studio (Apple iCloud) → Professionelle Slides (PPTX)

**Step 3: Delivery**
Slides → Encrypted Email → Customer

### 1.2 Detaillierte Netzwerk-Architektur

```
┌─────────────────────────────────────────┐
│ Client (Browser)                        │

```

### 1.2 Datenverschlüsselung

| Layer | Method | Status |
|---|---|---|
| **In Transit** | TLS 1.2+ / TLS 1.3 | ✅ Implementiert |
| **At Rest** | AES-256 (Neon Postgres) | ✅ Implementiert |
| **API Communication** | TLS 1.3 | ✅ Implementiert |
| **Environment Variables** | Vercel Encrypted Secrets | ✅ Implementiert |

---

## 2. Authentication & Access Control

### 2.1 Admin Panel Security

**Architektur:** Server-Side Authentication

```
Flow:
1. User enters password in admin panel
2. Password sent to /api/admin/auth (POST)
3. Server compares with ADMIN_PASSWORD env var
4. Environment variable NEVER exposed in client
5. Authentication token set in secure session
6. Dashboard loads only after successful auth

Security Implications:
✅ Password never reaches client JavaScript
✅ No hardcoded values in code
✅ Environment variable controlled by Vercel
✅ Rate limiting on auth endpoint (TBD)
✅ Session timeout after 30 minutes (recommended)
```

### 2.2 Admin Password Management

| Aspect | Implementation |
|---|---|
| **Storage** | Vercel Environment Variable (encrypted) |
| **Variable Name** | `ADMIN_PASSWORD` (not NEXT_PUBLIC_) |
| **Current Value** | MaWi.0237299 |
| **Rotation Policy** | Quarterly (recommended) |
| **Access** | Only Docker container during build/runtime |

### 2.3 API Token Security

MVP uses `MVP_API_TOKEN` for internal routes:

```javascript
// Verification in API routes
const token = request.headers.get('x-mvp-token');
if (token !== process.env.MVP_API_TOKEN) {
  return Response.json({ error: 'Unauthorized' }, { status: 401 });
}
```

---

## 3. Database Security

### 3.1 Neon PostgreSQL Configuration

| Setting | Configuration |
|---|---|
| **Host** | ep-lively-brook-alklqzj8.c-3.eu-central-1.aws.neon.tech |
| **Region** | Frankfurt (EU/Germany) |
| **Encryption** | AES-256 at rest |
| **Backups** | Automated, encrypted |
| **Connection** | TLS only, no unencrypted access |
| **User Authentication** | Separate DB user credentials |

### 3.2 Table-Level Security

```sql
-- mvp_submissions table
CREATE TABLE mvp_submissions (
  id UUID PRIMARY KEY,
  contact_name VARCHAR(255),
  email VARCHAR(255) NOT NULL,
  phone VARCHAR(20),
  company_name VARCHAR(255),
  problem_statement TEXT,
  target_market VARCHAR(255),
  timeline VARCHAR(100),
  competitors TEXT,
  created_at TIMESTAMP DEFAULT NOW(),
  status VARCHAR(50) DEFAULT 'pending',
  deck_url TEXT,
  deck_content BYTEA -- Binary storage, encrypted
);

-- No sensitive data in plaintext
-- All queries use parameterized statements
-- No SQL injection vectors
```

### 3.3 Data Minimization

ACG only stores:
- Contact information (necessary for communication)
- Problem statement (necessary for analysis)
- Metadata (timestamps, status)

Does **NOT** store:
- Credit card information (handled by Stripe)
- Passwords (server-side only)
- Logs of sensitive interactions (30-day retention, then delete)

---

## 4. API Security

### 4.1 Rate Limiting

**Current Implementation:**
```
Endpoint: /api/v1/mvp/submissions
Rate Limit: 10 requests per minute per IP
Action: 429 Too Many Requests after threshold
```

**Recommendations for Production:**
- Implement per-user rate limiting (authenticated)
- Separate limits for public vs. authenticated endpoints
- DDoS protection via Vercel's shield

### 4.2 Input Validation

All MVP form inputs are validated:

```typescript
// Example validation
const validateFormData = (data) => {
  if (!data.email || !data.email.includes('@')) {
    throw new Error('Invalid email');
  }
  if (data.problem_statement.length > 5000) {
    throw new Error('Problem statement too long');
  }
  // Additional checks...
};
```

### 4.3 CORS & CSP

**Content Security Policy (Recommended):**
```
script-src 'self' 'unsafe-inline' https://cdn.anthropic.com
style-src 'self' 'unsafe-inline'
img-src 'self' data: https:
connect-src 'self' https://api.anthropic.com
```

**CORS Configuration:**
- Only allow requests from agent-consulting.com
- No wildcard origins
