# 🛡️ CSP Testing Results - Pre-Deployment Verification

## Test Date: Thursday, November 6, 2025

### ✅ CSP Header Verification

**Status:** CSP is properly configured and active

**Current CSP Policy:**
```
Content-Security-Policy: 
  default-src 'self' https://365devnet.eu https://*.365devnet.eu; 
  script-src 'self' 'unsafe-inline' 'wasm-unsafe-eval' https://chat.365devnet.eu; 
  style-src 'self' 'unsafe-inline'; 
  img-src 'self' data: https: blob:; 
  font-src 'self' data:; 
  connect-src 'self' https://365devnet.eu https://*.365devnet.eu https://chat.365devnet.eu https://git.365devnet.eu wss://chat.365devnet.eu; 
  frame-src 'self' https://chat.365devnet.eu; 
  frame-ancestors 'none'; 
  base-uri 'self'; 
  form-action 'self'
```

### 🔍 External Resource Audit

All external domains have been identified and added to CSP:

| Resource | Domain | CSP Directive | Status |
|----------|--------|---------------|--------|
| Latest Commits | `https://git.365devnet.eu` | `connect-src` | ✅ Added |
| RocketChat Widget | `https://chat.365devnet.eu` | `script-src`, `connect-src`, `frame-src` | ✅ Included |
| RocketChat WebSocket | `wss://chat.365devnet.eu` | `connect-src` | ✅ Included |
| Images (any HTTPS) | `https:` | `img-src` | ✅ Wildcard |
| Internal APIs | `https://*.365devnet.eu` | `connect-src` | ✅ Wildcard |
| Uptime Kuma | Server-side only | N/A | ✅ No CSP needed |

### 📊 Client-Side vs Server-Side Calls

**Client-side calls (affected by CSP):**
- `/api/commits` → Internal (OK)
- `/api/contact` → Internal (OK)
- `/api/uptime` → Internal (OK)
- RocketChat widget → `chat.365devnet.eu` (Added to CSP)

**Server-side calls (NOT affected by CSP):**
- API routes fetch from `git.365devnet.eu` ✅
- API routes fetch from `UPTIME_KUMA_URL` ✅

### 🧪 Testing Performed

#### 1. Build Test
```bash
npm run build
```
**Result:** ✅ Build successful (astro-compress warning is harmless)

#### 2. CSP Enabled Server Test  
```bash
ENABLE_SSR_CSP=1 npm run start
```
**Result:** ✅ Server started successfully on port 3000

#### 3. CSP Header Present
```bash
curl -I http://localhost:3000/en/
```
**Result:** ✅ CSP header is present and correctly formatted

### 🎯 Key Fixes Applied

#### Fix #1: Added `git.365devnet.eu` to `connect-src`
**Problem:** Latest Commits widget was calling Gitea API but domain wasn't in CSP  
**Solution:** Added `https://git.365devnet.eu` to `connect-src`

#### Fix #2: Made `img-src` more permissive
**Problem:** Too restrictive, only allowed specific domains  
**Solution:** Changed to `https:` to allow all HTTPS images

#### Fix #3: Added wildcard subdomain support
**Problem:** Only specific subdomains were allowed  
**Solution:** Added `https://*.365devnet.eu` to `connect-src`

#### Fix #4: Kept `'unsafe-inline'` for scripts
**Problem:** Astro's inline scripts require this directive  
**Solution:** Included `'unsafe-inline'` in `script-src`

### ⚠️ Manual Testing Required

Before deploying to production, **manually test these features** with CSP enabled:

**Test URL:** http://localhost:3000/en/ (with `npm run dev:prod` or `ENABLE_SSR_CSP=1 npm run start`)

#### Features to Test:

- [ ] **Mobile Menu Toggle**
  - Open site on mobile (or use browser DevTools responsive mode)
  - Click hamburger menu icon
  - Menu should expand/collapse
  - Check console for CSP violations

- [ ] **Language Selector**
  - Desktop: Click language dropdown
  - Select different language
  - Page should reload with new language
  - Mobile: Use select dropdown

- [ ] **Theme Switcher**
  - Click sun/moon icon
  - Theme should toggle between light/dark
  - Preference should persist

- [ ] **Contact Form**
  - Fill out form
  - Submit
  - Check for successful submission
  - Check console for CSP violations

- [ ] **Latest Commits Widget** ← Critical test!
  - Navigate to `/en/development/`
  - Widget should load commit history
  - Check browser console for errors
  - Verify commits are displayed

- [ ] **RocketChat Widget**
  - Widget should appear in bottom right
  - Should be clickable and functional
  - Check console for CSP violations

- [ ] **Smooth Scrolling**
  - Click any anchor link (e.g., "Services" in nav)
  - Page should scroll smoothly
  - No console errors

- [ ] **Images Loading**
  - All images should load correctly
  - Check different pages
  - No broken images

### 🔧 Debugging Tips

#### If Something Doesn't Work:

1. **Open Browser DevTools** (F12)
2. **Go to Console tab**
3. **Look for red CSP violation errors:**
   ```
   Refused to load ... because it violates CSP directive...
   ```

4. **Identify the blocked resource:**
   - What domain?
   - What type? (script, style, image, fetch, etc.)

5. **Add to appropriate CSP directive:**
   - Scripts → `script-src`
   - API calls → `connect-src`
   - Images → `img-src`
   - Styles → `style-src`

6. **Rebuild and test again**

### 📝 Deployment Checklist

Before enabling CSP in production:

- [ ] Run `npm run dev:prod` locally
- [ ] Complete all manual tests above
- [ ] Check browser console (no CSP violations)
- [ ] Test on Chrome, Firefox, and Safari
- [ ] Test on actual mobile device
- [ ] Verify Latest Commits widget works
- [ ] Verify RocketChat widget works
- [ ] Document any new CSP changes

### 🚀 Deployment Instructions

#### Option 1: Full Test (Recommended)
```bash
# Build and test locally with CSP
npm run dev:prod

# Manual testing...

# If all tests pass, rebuild Docker
docker-compose up -d --build
```

#### Option 2: Direct Deploy (Use with caution)
```bash
# Make sure ENABLE_SSR_CSP=1 is in docker-compose.yml
docker-compose up -d --build

# Monitor logs
docker-compose logs -f web

# Check production site immediately
# Open browser DevTools and check console
```

### 📊 Confidence Level

**Current Status:**
- ✅ CSP policy created and verified
- ✅ All external domains identified
- ✅ Server runs with CSP enabled
- ✅ CSP header present in responses
- ⚠️ Manual browser testing required

**Confidence for Production:** 85%

**Why not 100%?** Manual browser testing of interactive features (mobile menu, language selector, Latest Commits widget) has not been performed with CSP enabled. This requires opening a browser and testing each feature while monitoring the console for CSP violations.

### 🎯 Recommendation

**Before deploying to production:**

1. Run `npm run dev:prod`
2. Open http://localhost:3000/en/ in your browser
3. Open DevTools Console (F12)
4. Test each interactive feature
5. Verify NO CSP violation errors appear
6. **Especially test Latest Commits widget** - this was the main issue!

If all tests pass → **Deploy with confidence!** ✅  
If CSP violations appear → **Document them and add domains to CSP** 🔧
