# GCP - Permissions for a Pentest

Si vous souhaitez effectuer un pentest dans un environnement **GCP**, vous devez demander suffisamment de permissions pour **vérifier tous ou la plupart des services** utilisés dans **GCP**. Idéalement, vous devriez demander au client de créer :

* **Créer** un **nouveau projet**
* **Créer** un **compte de service** à l'intérieur de ce projet (obtenir des **identifiants json**) ou créer un **nouvel utilisateur**.
* **Donner** au **compte de service** ou à l'**utilisateur** les **rôles** mentionnés plus tard sur l'ORGANISATION
* **Activer** les **API** mentionnées plus tard dans ce post dans le projet créé

**Ensemble de permissions** à utiliser avec les outils proposés plus tard :
```bash
roles/viewer
roles/resourcemanager.folderViewer
roles/resourcemanager.organizationViewer
```
APIs à activer (de starbase) :
```
