+# Security Audit Report - WorkRoot IT Solutions
+
+**Domain Migration**: `workroot.com` → `workroot.in`
+**Audit Date**: 2026-03-21
+**Auditor**: security-auditor agent
+**Status**: ✅ PASS (with recommendations implemented)
+
+---
+
+## Executive Summary
+
+This security audit was performed following the domain migration from `workroot.com` to `workroot.in`. The audit focused on:
+
+1. ✅ **CORS Settings**: No explicit CORS configuration found (server-side rendering mode)
+2. ✅ **CSP Headers**: Implemented via middleware
+3. ✅ **Authentication/Redirects**: No authentication system; domain validation implemented
+4. ✅ **Security Headers**: Comprehensive headers implemented
+5. ✅ **Domain References**: All updated to `workroot.in`
+
+**Overall Risk Level**: 🟢 **LOW** (after implementing recommendations)
+
+---
+
+## 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` |
+| Sitemap Generator | ✅ 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
+
