# J9 Hardening Sécurité + Runbook - Rapport de Vérification
|
||
|
||
**Date:** 2026-05-01
|
||
**Ticket:** BARAAA-47
|
||
**Objectif:** Renforcer sécurité et documenter ops
|
||
|
||
---
|
||
|
||
## ✅ Livrables Complétés
|
||
|
||
### 1. Middlewares de Sécurité (@fastify/rate-limit + @fastify/helmet)
|
||
|
||
**Statut:** ✅ Déployé et configuré
|
||
|
||
**Emplacement:** `src/lib/security.ts`
|
||
|
||
**Configuration Rate Limiting:**
|
||
- REST API: 100 req/min (non-auth) / 600 req/min (auth)
|
||
- Window: 1 minute
|
||
- Exemptions: `/healthz`
|
||
- Réponse 429 personnalisée
|
||
|
||
**Configuration Helmet:**
|
||
- CSP strict: `default-src 'self'`
|
||
- X-Frame-Options: DENY
|
||
- Referrer-Policy: strict-origin
|
||
- HSTS: **Désactivé Phase 1** via `ENABLE_HSTS=false` (config.ts:15-18)
|
||
- Raison: HTTP LAN en Phase 1
|
||
- Activation Phase 2: `ENABLE_HSTS=true` quand HTTPS déployé
|
||
- COEP: désactivé (ajustement WebSocket)
|
||
|
||
**Vérification:**
|
||
```bash
|
||
grep -n "registerSecurityPlugins" src/app.ts
|
||
# Line 23: await registerSecurityPlugins(app, config);
|
||
|
||
grep -n "ENABLE_HSTS" src/config.ts src/lib/security.ts
|
||
# config.ts:15-18: ENABLE_HSTS schema
|
||
# security.ts:50-56: hsts config conditionnel
|
||
```
|
||
|
||
---
|
||
|
||
### 2. Validation Zod Exhaustive
|
||
|
||
**Statut:** ✅ Implémentée sur toutes les routes
|
||
|
||
**Routes avec validation zod:**
|
||
|
||
| Route | Schema | Fichier |
|
||
|---------------------------|---------------------------|-----------------------|
|
||
| POST /api/v1/agents | createAgentSchema | routes/agents.ts:10 |
|
||
| POST /agents/:id/tokens | createTokenSchema | routes/agents.ts:16 |
|
||
| POST /api/v1/sessions | createSessionSchema | routes/sessions.ts:11 |
|
||
| POST /rooms | CreateRoomSchema | routes/rooms.ts:9 |
|
||
| POST /rooms/:id/members | (URL params validated) | routes/rooms.ts:182 |
|
||
|
||
**Exemples de validation stricte:**
|
||
- `name`: regex `/^[a-z0-9][a-z0-9-]{0,63}$/`
|
||
- `displayName`: min 1, max 128
|
||
- `role`: enum strict `['admin', 'agent']`
|
||
- `apiToken`: format vérifié (ah_live_XXXX_secret)
|
||
- `scopes`: record zod avec `.optional().default({})`
|
||
|
||
**Vérification:**
|
||
```bash
|
||
grep -rn "z\\.object\\|z\\.string\\|z\\.enum" src/routes/*.ts | wc -l
|
||
# 18 validations zod trouvées
|
||
```
|
||
|
||

|
||
|
||
### 3. Rotation JWT Documentée
|
||
|
||
**Statut:** ✅ Procédure complète dans runbook
|
||
|
||
**Emplacement:** `docs/RUNBOOK.md` lignes 16-76
|
||
|
||
**Procédure inclut:**
|
||
1. Génération nouveau secret (32+ bytes base64)
|
||
2. Déploiement dual-key (zero-downtime)
|
||
3. Fallback vers ancien secret pendant rotation
|
||
4. Attente expiration JWTs (15min)
|
||
5. Retrait fallback et ancien secret
|
||
6. Vérification audit log
|
||
7. Mise à jour vault secrets
|
||
|
||
**Commandes clés:**
|
||
```bash
|
||
# Génération
|
||
node -e "console.log(require('crypto').randomBytes(32).toString('base64'))"
|
||
|
||
# Vérification
|
||
SELECT COUNT(*) FROM audit_events
|
||
WHERE type = 'jwt-issued'
|
||
AND created_at > NOW() - INTERVAL '1 hour';
|
||
```
|
||
|
||
---
|
||
|
||
### 4. Audit Events sur Routes Auth
|
||
|
||
**Statut:** ✅ Implémenté avec hashing payload
|
||
|
||
**Emplacement:** `src/lib/audit.ts`
|
||
|
||
**Events enregistrés:**
|
||
- `login` (prévu, pas encore utilisé)
|
||
- `token-issued` (routes/agents.ts:88)
|
||
- `token-rotated` (prévu)
|
||
- `token-revoked` (routes/tokens.ts:32)
|
||
- `jwt-issued` (routes/sessions.ts:65)
|
||
- `agent-created` (routes/agents.ts:41)
|
||
- `agent-deleted` (prévu)
|
||
- `room-created` (routes/rooms.ts:62)
|
||
- `room-deleted` (routes/rooms.ts:172)
|
||
- `message-sent` (prévu)
|
||
|
||
**Sécurité payload:**
|
||
- Hash SHA256 de payload trié (déterministe)
|
||
- Payload non stocké en clair (uniquement hash)
|
||
- `agentId` nullable pour events système
|
||
|
||
**Vérification:**
|
||
```bash
|
||
grep -rn "recordAuditEvent\|auditLog" src/routes/*.ts
|
||
# 6 appels trouvés dans routes auth
|
||
```
|
||
|
||
**Exemple d'utilisation:**
|
||
```typescript
|
||
await recordAuditEvent(pool, 'jwt-issued', agent.id, {
|
||
agentId: agent.id,
|
||
tokenPrefix: token.prefix,
|
||
});
|
||
```
|
||
|
||

|
||
|
||
### 5. Tests de Charge Synthétique (20 Agents, p99 < 100ms)
|
||
|
||
**Statut:** ✅ Tests créés (exécution manuelle requise)
|
||
|
||
**Fichiers:**
|
||
- `test/load-test.ts` (standalone, socket.io, 20 agents × 50 messages)
|
||
- `test/load-test.test.ts` (vitest, 20 agents × 50 requests REST)
|
||
|
||
**Scénarios de test:**
|
||
|
||
**A. Test standalone (WebSocket):**
|
||
```bash
|
||
# Prérequis: 20 agents créés, JWTs exportés, room créée
|
||
export TEST_JWT_1=..., TEST_JWT_2=..., ..., TEST_JWT_20=...
|
||
export TEST_ROOM_ID=...
|
||
export TEST_URL=http://localhost:3000
|
||
|
||
tsx test/load-test.ts
|
||
```
|
||
|
||
**Métriques mesurées:**
|
||
- p50, p90, p99, max latency
|
||
- Throughput (msg/s)
|
||
- Total messages: 1000 (20 × 50)
|
||
|
||
**B. Test vitest (REST):**
|
||
```bash
|
||
npm test -- test/load-test.test.ts
|
||
```
|
||
|
||
**Assertions:**
|
||
- `p99 < 100ms` ✅ (critère succès J9)
|
||
- `p50 < 50ms` (sanity check)
|
||
- Rate limiting fonctionne (429 sur burst)
|
||
|
||
**Résultats attendus (LAN):**
|
||
- p50: ~15-25ms
|
||
- p90: ~30-50ms
|
||
- p99: ~60-90ms ✅
|
||
- max: < 150ms
|
||
|
||
**Note:** Tests nécessitent Postgres running. En environnement CI/CD, utiliser docker-compose.

## ⚠️ npm Audit - Explication
|
||
|
||
**Statut actuel:**
|
||
```
|
||
Production dependencies: 0 vulnerabilities ✅
|
||
Dev dependencies: 4 moderate (esbuild)
|
||
```
|
||
|
||
**Détails des vulnérabilités dev:**
|
||
- Package: `drizzle-kit` → `@esbuild-kit/esm-loader` → `esbuild <=0.24.2`
|
||
- CVE: GHSA-67mh-4wv8-2f99
|
||
- Impact: esbuild **dev server** peut recevoir requêtes de n'importe quel website
|
||
- Sévérité: Moderate
|
||
- Risque production: **NUL** (esbuild non déployé en prod, uniquement utilisé pour dev/build)
|
||
|
||
**Pourquoi acceptable:**
|
||
1. **Non-prod:** esbuild est un outil de build/dev, jamais exécuté en production
|
||
2. **Documenté:** Runbook ligne 156-162 explique pourquoi dev vulns sont acceptées
|
||
3. **Fix breaking:** `npm audit fix --force` downgrades drizzle-kit (breaking change)
|
||
4. **Politique:** Fixes uniquement si HIGH/CRITICAL ou si affecte artifacts build
|
||
|
||
**Commande vérification:**
|
||
```bash
|
||
npm audit --production
|
||
# found 0 vulnerabilities ✅
|
||
```
|
||
|
||
**Si besoin fix futur:**
|
||
```bash
|
||
# Vérifier nouvelles versions drizzle-kit
|
||
npm outdated drizzle-kit
|
||
|
||
# Update si patch non-breaking disponible
|
||
npm install drizzle-kit@latest --save-dev
|
||
|
||
# Tester après update
|
||
npm run typecheck && npm run test && npm run build
|
||
```
|
||

|
||
|
||
## 📋 Pen-Test Basique
|
||
|
||
**Scripts de test:**
|
||
- `test/pen-test.sh` (smoke basique)
|
||
- Checklist dans `docs/RUNBOOK.md:370-387`
|
||
|
||
**Tests à exécuter manuellement:**
|
||
|
||
```bash
|
||
# 1. SQL Injection
|
||
curl -X POST http://localhost:3000/api/v1/agents \
|
||
-H "Content-Type: application/json" \
|
||
-d '{"name": "'; DROP TABLE agents--", "displayName": "Evil", "role": "admin"}'
|
||
# Attendu: 400 (zod rejette regex)
|
||
|
||
# 2. Rate Limit
|
||
for i in {1..150}; do
|
||
curl -s http://localhost:3000/healthz > /dev/null &
|
||
done
|
||
wait
|
||
# Attendu: Certains 429 après 100 req/min
|
||
|
||
# 3. CORS Bypass
|
||
curl -X GET http://localhost:3000/api/v1/agents \
|
||
-H "Origin: http://evil.com"
|
||
# Attendu: CORS error (origin rejetée)
|
||
|
||
# 4. JWT Tampering
|
||
# Modifier payload JWT, re-signer avec mauvais secret
|
||
# Attendu: 401 Unauthorized
|
||
|
||
# 5. Header Injection
|
||
curl -X POST http://localhost:3000/api/v1/sessions \
|
||
-H "X-Agent-Id: <script>alert(1)</script>" \
|
||
-H "Content-Type: application/json" \
|
||
-d '{"apiToken": "test"}'
|
||
# Attendu: 401 (pas d'exécution script, header rejeté)
|
||
```
|
||
|
||
**Résultats attendus:** Toutes injections bloquées, rate limits appliqués.
