| 3 | +## Protected Features - Production Security |
| 4 | + |
| 5 | +This document verifies that all protected features are properly secured in production and cannot be accessed without proper authentication. |
| 6 | + |
| 7 | +--- |
| 8 | + |
| 9 | +## ✅ Security Measures in Place |
| 10 | + |
| 11 | +### 1. **Server-Side Authentication (GetServerSideProps)** |
| 12 | + |
| 13 | +All protected pages use `GetServerSideProps` which runs on the server **before** the page is rendered. This means: |
| 14 | +- Authentication is checked on the server, not the client |
| 15 | +- Users cannot bypass checks by manipulating browser JavaScript |
| 16 | +- Unauthenticated users are redirected before any protected content loads |
| 17 | + |
| 18 | +**Protected Pages:** |
| 19 | +- `/resume-translator` - Line 140 |
| 20 | +- `/courses` - Line 262 |
| 21 | +- `/courses/software-engineering` - Line 302 |
| 22 | +- `/courses/data-engineering` - Line 302 |
| 23 | +- `/courses/ai-engineering` - Line 302 |
| 24 | +- `/courses/web-development` - Line 421 |
| 25 | +- `/courses/devops` - Line 420 |
| 26 | +- `/courses/web-development/[moduleId]/[lessonId]` - Line 419 |
| 27 | +- `/jobs` - Line 347 (already had it) |
| 28 | + |
| 29 | +### 2. **GitHub Organization Membership Verification** |
| 30 | + |
| 31 | +**File:** `src/pages/api/auth/options.ts` (Lines 56-96) |
| 32 | + |
| 33 | +In production, the login flow: |
| 34 | +1. User signs in with GitHub OAuth |
| 35 | +2. System checks if user is in "Vets-Who-Code" GitHub org via API call |
| 36 | +3. HTTP 204 response = member, allowed to proceed |
| 37 | +4. Any other response = denied access |
| 38 | + |
| 39 | +**Exception:** Only `jeromehardaway` can login as admin regardless of org membership (Line 52) |
| 40 | + |
| 41 | +**Development:** All GitHub users can login for testing (Line 47) |
| 42 | + |
| 43 | +### 3. **Dev Login Protection** |
| 44 | + |
| 45 | +**File:** `src/pages/dev-login.tsx` (Lines 91-100) |
| 46 | + |
| 47 | +```typescript |
| 48 | +if (process.env.NODE_ENV !== "development") { |
| 49 | + return { |
| 50 | + redirect: { |
| 51 | + destination: "/", |
| 52 | + permanent: false, |
| 53 | + }, |
| 54 | + }; |
| 55 | +} |
| 56 | +``` |
| 57 | + |
| 58 | +- In production, `/dev-login` redirects to homepage |
| 59 | +- Dev login button is hidden in production (conditional rendering) |
| 60 | +- Dev session API endpoint returns 403 in production |
| 61 | + |
| 62 | +**File:** `src/pages/api/auth/dev-session.ts` (Lines 10-12) |
| 63 | + |
| 64 | +```typescript |
| 65 | +if (process.env.NODE_ENV !== 'development') { |
| 66 | + return res.status(403).json({ error: 'Not available in production' }); |
| 67 | +} |
| 68 | +``` |
| 69 | + |

| 72 | +## 🔒 Security Verification Checklist |
| 73 | + |
| 74 | +### Client-Side Bypasses - PREVENTED ✅ |
| 75 | + |
| 76 | +- ❌ **Cannot** bypass auth by manipulating localStorage |
| 77 | + - *Why:* All auth checks happen server-side via `getServerSession()` |
| 78 | + - *Old approach removed:* No longer checking `localStorage.getItem("dev-session")` |
| 79 | + |
| 80 | +- ❌ **Cannot** bypass auth by manipulating browser DevTools |
| 81 | + - *Why:* Server-side rendering checks auth before sending HTML |
| 82 | + |
| 83 | +- ❌ **Cannot** access `/dev-login` in production |
| 84 | + - *Why:* `GetServerSideProps` redirects to "/" in production |
| 85 | + |
| 86 | +### Server-Side Bypasses - PREVENTED ✅ |
| 87 | + |
| 88 | +- ❌ **Cannot** access dev-session API in production |
| 89 | + - *Why:* Returns 403 if `NODE_ENV !== 'development'` |
| 90 | + |
| 91 | +- ❌ **Cannot** forge NextAuth session |
| 92 | + - *Why:* Sessions are validated against database and signed with secret |
| 93 | + |
| 94 | +- ❌ **Cannot** access protected pages without GitHub org membership |
| 95 | + - *Why:* Org membership verified during login via GitHub API |
| 96 | + |
| 97 | +### Environment-Based Security ✅ |
| 98 | + |
| 99 | +**Development Mode (`NODE_ENV=development`):** |
| 100 | +- ✅ Dev login accessible for testing |
| 101 | +- ✅ All GitHub users can login |
| 102 | +- ✅ Dev-session API works |
| 103 | +- ✅ localStorage dev-session (legacy, not used on protected pages) |
| 104 | + |
| 105 | +**Production Mode (`NODE_ENV=production`):** |
| 106 | +- ✅ Dev login redirects to homepage |
| 107 | +- ✅ Only Vets-Who-Code org members + jeromehardaway can login |
| 108 | +- ✅ Dev-session API returns 403 |
| 109 | +- ✅ All protected pages require valid NextAuth session |
| 110 | + |
