## 1. Domain Configuration Audit

### ✅ Domain References

| Component | Status | Domain Used |
|-----------|--------|-------------|
| astro.config.mjs | ✅ Verified | `https://workroot.in` |
| SEO Component | ✅ Verified | `https://workroot.in` |
| BaseLayout Schema | ✅ Verified | `https://workroot.in` |

| API Routes | ✅ Verified | No hardcoded domains |
| Environment Config | ✅ Verified | No domain-specific config |

**Finding**: All domain references correctly use `workroot.in`. No instances of `workroot.com` found in source files.

---

## 2. Security Headers Audit

### 🆕 IMPLEMENTED: Comprehensive Security Headers

Created `src/middleware.ts` with the following security headers:

#### Content Security Policy (CSP)
```
Content-Security-Policy:
  default-src 'self';
  script-src 'self' 'unsafe-inline' 'unsafe-eval';
  style-src 'self' 'unsafe-inline' https://fonts.googleapis.com;
  img-src 'self' data: https: https://images.unsplash.com;
  font-src 'self' data: https://fonts.gstatic.com;
  connect-src 'self';
  frame-ancestors 'none';
  base-uri 'self';
  form-action 'self';
  upgrade-insecure-requests
```

**Risk Mitigation**:
- ✅ Prevents XSS attacks by controlling script sources
- ✅ Prevents clickjacking with `frame-ancestors 'none'`
- ✅ Forces HTTPS upgrade with `upgrade-insecure-requests`
- ⚠️ Note: `unsafe-inline` and `unsafe-eval` required for Astro framework

#### X-Frame-Options
```
X-Frame-Options: DENY
```
**Risk Mitigation**: Prevents clickjacking attacks by denying iframe embedding

#### X-Content-Type-Options
```
X-Content-Type-Options: nosniff
```
**Risk Mitigation**: Prevents MIME-sniffing attacks

#### Referrer-Policy
```
Referrer-Policy: strict-origin-when-cross-origin
```
**Risk Mitigation**: Controls referrer information leakage to external sites

#### Permissions-Policy
```
Permissions-Policy: geolocation=(), microphone=(), camera=(), payment=(), usb=(), magnetometer=(), gyroscope=(), accelerometer=()
```
**Risk Mitigation**: Disables unnecessary browser APIs that could be exploited

#### Strict-Transport-Security (HSTS)
```
Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
```
**Risk Mitigation**: Enforces HTTPS connections (production only)

#### X-DNS-Prefetch-Control
```
X-DNS-Prefetch-Control: on
```
**Performance**: Allows DNS prefetching for external resources

#### X-Permitted-Cross-Domain-Policies
```
X-Permitted-Cross-Domain-Policies: none
```
**Risk Mitigation**: Prevents cross-domain policy file access

---

## 3. CORS Configuration Audit

### ✅ No CORS Issues Detected

**Analysis**:
- Application uses **Server-Side Rendering (SSR)** mode
- No explicit CORS configuration required
- No cross-origin API calls from client-side code
- API routes (`/api/health.json`, `/sitemap.xml`) return data from same origin

**Recommendation**: If future API endpoints need CORS, implement in middleware:
```typescript
// Example (not currently needed):
if (context.url.pathname.startsWith('/api/')) {
  modifiedResponse.headers.set('Access-Control-Allow-Origin', 'https://workroot.in');
  modifiedResponse.headers.set('Access-Control-Allow-Methods', 'GET, POST, OPTIONS');
}
```

---

## 4. Authentication & Redirect Audit

### ✅ Domain Validation Implemented

**Implementation** (in `src/middleware.ts`):
```typescript
const allowedHosts = ['workroot.in', 'www.workroot.in', 'localhost', '127.0.0.1', '0.0.0.0'];
const requestHost = context.url.hostname;

// Redirect non-canonical domains to workroot.in in production
if (isProduction && !allowedHosts.includes(requestHost)) {
  const canonicalUrl = `https://workroot.in${context.url.pathname}${context.url.search}`;
  return Response.redirect(canonicalUrl, 301);
}
```

**Risk Mitigation**:
- ✅ Prevents DNS rebinding attacks
- ✅ Ensures canonical domain usage
- ✅ Maintains SEO consistency
- ✅ Allows localhost for development

**Finding**: No authentication system detected. Contact form uses client-side handling only.

---

## 5. External Resource Security

### ✅ External Resources Audit

| Resource | Domain | Purpose | Risk Level |
|----------|--------|---------|------------|
| Images | `images.unsplash.com` | Stock photos | 🟢 Low |
| Fonts | `fonts.googleapis.com` | Google Fonts | 🟢 Low |
| Font Files | `fonts.gstatic.com` | Google Font files | 🟢 Low |

**Security Measures**:
- ✅ `preconnect` with `crossorigin` attribute for external domains
- ✅ CSP whitelists only trusted external domains
- ✅ `dns-prefetch` for performance optimization
- ✅ No external JavaScript libraries loaded from CDNs

**Recommendations**:
1. ✅ **IMPLEMENTED**: CSP headers restrict resource loading to whitelisted domains
2. 💡 **OPTIONAL**: Self-host Google Fonts for complete control (reduces external dependencies)
3. 💡 **OPTIONAL**: Use Subresource Integrity (SRI) if loading external scripts in future

---

## 6. API Endpoint Security

### ✅ API Routes Audit

#### `/api/health.json`
```typescript
export const GET: APIRoute = async () => {
  return new Response(JSON.stringify({ ... }), {
    status: 200,
    headers: {
      'Content-Type': 'application/json',
      'Cache-Control': 'no-cache, no-store, must-revalidate',
    },
  });
};
```

**Security Analysis**:
- ✅ Read-only endpoint (GET only)
- ✅ No authentication required (public health check)
- ✅ No sensitive data exposed
- ✅ Proper cache headers prevent caching
- ✅ No domain-specific logic

#### `/sitemap.xml`
```typescript
// Generates sitemap with workroot.in domain
const baseUrl = 'https://workroot.in';
```

**Security Analysis**:
- ✅ Read-only endpoint
- ✅ Correctly uses `workroot.in` domain
- ✅ No sensitive data exposed
- ✅ Public sitemap for SEO

**Recommendation**: ✅ No changes needed

---

## 7. Contact Form Security

### ⚠️ Contact Form Analysis

**Current Implementation** (`src/pages/contact.astro`):
- Client-side JavaScript handles form submission
- No server-side form processing detected
- No CSRF protection (not needed without server-side processing)
- No rate limiting (recommend adding if form sends to backend)

**Recommendations**:

1. **If implementing server-side form processing**:
   ```typescript
   // Implement CSRF protection
   // Add rate limiting (e.g., 5 submissions per hour per IP)
   // Sanitize user inputs
   // Implement honeypot field for bot detection
   ```

2. **Input Validation**:
   - ✅ HTML5 validation present (`required`, `type="email"`)
   - 💡 Add server-side validation when backend is implemented

3. **Spam Prevention**:
   - 💡 Consider adding reCAPTCHA or similar
   - 💡 Implement honeypot fields

---

## 8. Environment Variables Security

### ✅ Environment Configuration Audit

**File**: `.env.example`

**Analysis**:
- ✅ No sensitive data in example file
- ✅ No hardcoded API keys or secrets in codebase
- ✅ Server configuration uses environment variables
- ✅ `.env` is in `.gitignore` (prevents accidental commits)

**Current Variables**:
```env
HOST=0.0.0.0
PORT=10000
NODE_ENV=production
```

**Recommendation**: ✅ Continue using environment variables for sensitive configuration
