Fournir des métadonnées pour les images

Vous pouvez choisir de fournir vos propres métadonnées de faille à Container Analysis pour répondre à un besoin professionnel spécifique. Par exemple, une organisation qui assure la gestion de la sécurité des conteneurs Docker de ses clients peut utiliser Container Analysis pour stocker et récupérer des métadonnées liées à la sécurité de ces images.

Suivez les étapes ci-dessous pour fournir des métadonnées de faille personnalisées pour vos images à l'aide de l'API Container Analysis. Vous pouvez utiliser les mêmes instructions pour stocker et récupérer tout type de métadonnées accepté par Container Analysis.

Avant de commencer

  1. Activez l'API Container Analysis.

  2. Lisez la présentation de Container Analysis.

  3. Découvrez comment configurer le contrôle d'accès de Container Analysis pour vos projets.

Créer des notes et des occurrences de failles pour des projets

Dans cette section, nous expliquons comment les fournisseurs tiers d'informations sur les failles peuvent créer des notes et des occurrences pour les projets de leurs utilisateurs.

En tant que fournisseur, vous créez une note dans votre projet pour chaque type de faille, et vous créez une occurrence dans le projet de votre client pour une occurrence de cette faille.

Créer des notes

Pour créer une note :

API

  1. Créez un fichier nommé note.json contenant une description ainsi que les détails de la faille. Le code suivant illustre un exemple de fichier note.json :

         {
             "shortDescription": "A brief Description of the note",
             "longDescription": "A longer description of the note",
             "kind": "PACKAGE_VULNERABILITY",
             "vulnerabilityType": {
                 "details": [
                 {
                     "package": "libexempi3",
                     "cpeUri": "cpe:/o:debian:debian_linux:7",
                     "minAffectedVersion": { "name": "2.5.7", "revision": "1"},
                     "maxAffectedVersion": { "name": "2.5.9", "revision": "1"},
                 },
                 {
                     "cpeUri": "something else"
                 }
                 ]
             }
         }
    
  2. Exécutez la commande curl ci-dessous pour créer une note, où [PROVIDER_PROJECT_ID] correspond à l'ID de votre projet :

    curl -X POST -H "Content-Type: application/json" -H \
        "Authorization: Bearer $(gcloud auth print-access-token)" \
        https://containeranalysis.googleapis.com/v1/projects/[PROVIDER_PROJECT_ID]/notes?note_id=[NOTE_ID] -d @note.json

Obtenir toutes les occurrences associées à une note spécifique

Vous pouvez afficher toutes les occurrences d'une faille spécifique dans l'ensemble des projets de votre client à l'aide de notes.occurrences.list().

API

Pour répertorier toutes les occurrences d'une note, envoyez une requête GET basée sur le modèle suivant :

GET https://containeranalysis.googleapis.com/v1/projects/PROJECT_ID/notes/NOTE_ID/occurrences

Reportez-vous au point de terminaison projects.notes.occurrences.list de l'API pour obtenir des informations complètes.
