Scan images for OS vulnerabilities automatically

Container Analysis provides vulnerability information for the container images in Container Registry and Artifact Registry. The metadata is stored as notes. An occurrence is created for each instance of a note associated with an image. See the overview and pricing documents for more information.

In this document you will learn how to enable the Container Analysis scanning API, push an image on Artifact Registry, and see the list of vulnerabilities found in the image.

Note: Enabling this API also triggers language package scans for Go and Java vulnerabilities.

Before you begin

1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

2. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   Go to project selector

3. Make sure that billing is enabled for your Cloud project. Learn how to check if billing is enabled on a project.

4. Enable the Container Scanning API.

   Enable the API

5. Install the Google Cloud CLI.

6. To initialize the gcloud CLI, run the following command:

   gcloud init

7. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   Go to project selector

8. Make sure that billing is enabled for your Cloud project. Learn how to check if billing is enabled on a project.

9. Enable the Container Scanning API.

   Enable the API

10. Install the Google Cloud CLI.

11. To initialize the gcloud CLI, run the following command:

    gcloud init

Important: When you enable the Container Scanning API, billing begins immediately. Once you enable the API for a project, Container Analysis automatically scans each newly pushed image to either Container Registry or Artifact Registry in that project. Container Analysis does not automatically scan existing images. To scan an existing image, you must push it again.

Create a repository and push a container image

Create a Docker repository in Artifact Registry and push a container image to the repository. If you are not familiar with Artifact Registry, see the Docker quickstart.

View the image vulnerabilities

Container Analysis scans new images when they're uploaded to Artifact Registry. This scan extracts information about the system packages in the container.

You can view vulnerability occurrences for your images in Container Registry or Artifact Registry using Google Cloud console, Google Cloud CLI, or the Container Analysis API. If an image has vulnerabilities, you can then obtain the details.

Container Analysis only updates the vulnerability metadata for images that were pushed or pulled in the last 30 days. Container Analysis archives vulnerability metadata that is older than 30 days. To re-scan an image with archived vulnerability metadata, push or pull that image.

Viewing occurrences in Google Cloud console

To see the vulnerabilities in an image:

1. Get the list of repositories.

   Open the Repositories page

2. In the repositories list, click a repository.

3. Click an image name.

   Vulnerability totals for each image digest are displayed in the Vulnerabilities column.

   

4. To view the list of vulnerabilities for an image, click the link in the Vulnerabilities column.

   The vulnerability list shows the severity, availability of a fix, and the name of the package that contains the vulnerability.

   Google Cloud console displays up to 1200 vulnerabilities. If your image has more than 1200 vulnerabilities, use gcloud or the API to view the full list.

5. To learn more about a specific vulnerability from the vulnerability source, click the link in the Documentation column.

Viewing occurrences using gcloud

Preview

This product or feature is covered by the Pre-GA Offerings Terms of the Google Cloud Terms of Service. Pre-GA products and features might have limited support, and changes to pre-GA products and features might not be compatible with other pre-GA versions. For more information, see the launch stage descriptions.

If you're using Cloud Build, you can also view image vulnerabilities in the Security insights side panel within the Google Cloud console.

The Security insights side panel provides a high-level overview of build security information for artifacts stored in Artifact Registry. To learn more about the side panel and how you can use Cloud Build to help protect your software supply chain, see View build security insights.

Filtering occurrences

You can use filter strings in the gcloud commands and the Container Analysis API to filter occurrences before viewing them. The following sections describe the supported search filters.

Viewing discovery occurrences

When an image is initially pushed to the Container Registry, it creates a discovery occurrence, which contains information about the initial scan of the container image.

To retrieve the discovery occurrence for an image, use the following filter expression:

kind="DISCOVERY" AND resourceUrl="RESOURCE_URL"

The following snippet shows how to use the above filter expression to view discovery occurrences for an image. The code snippets specify URLs for images in Container Registry. If you are using Artifact Registry, specify images with a URL in the format:

LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE_ID

gcloud CLI

To view discovery occurrences for an image:

In this case the expression is not used directly in the command, but the same information is passed as arguments:

Artifact Registry:

gcloud artifacts docker images list --show-occurrences \
--occurrence-filter='kind="DISCOVERY"' --format=json \
LOCATION-docker.pkg.dev/PROJECT_ID/REPOSITORY/IMAGE_ID

Container Registry:

gcloud beta container images list-tags \
--occurrence-filter='kind="DISCOVERY"' --format=json HOSTNAME/PROJECT_ID/IMAGE_ID

API

To retrieve the discovery occurrence, the above filter expression should be URL encoded and embedded in a GET request as follows:

GET https://containeranalysis.googleapis.com/v1/projects/PROJECT_ID/occurrences?filter=kind%3D%22DISCOVERY%22%20AND%20resourceUrl%3D%22ENCODED_RESOURCE_URL%22

Viewing occurrences of a specific type

In the two previous examples the only difference between the filter expressions is the value of kind, which identifies the type of occurrence. Use this field to limit the list of occurrences to a particular type, such as a vulnerability or deployment.

To retrieve occurrences for a specific image, use this filter expression:

kind="NOTE_KIND" AND resourceUrl="RESOURCE_URL"

Where:

• NOTE_KIND is the kind of note.
  • For example, use the kind DISCOVERY to list discovery occurrences. These are created for images when they are initially pushed to the Container Registry.
  • To list vulnerability occurrences, use the kind VULNERABILITY.
• RESOURCE_URL is the complete URL of the image https://HOSTNAME/PROJECT_ID/IMAGE_ID@sha256:HASH

The filter expression to retrieve occurrences of a specific kind across many images is:

kind="NOTE_KIND" AND has_prefix(resourceUrl, "RESOURCE_URL_PREFIX")

Where:

• RESOURCE_URL_PREFIX is the URL prefix for some images
  • To list for all version of an image: https://HOSTNAME/PROJECT_ID/IMAGE_ID@
  • To list for all images in a project: https://HOSTNAME/PROJECT_ID/

Note: This syntax is not supported by the gcloud command.

Viewing images associated with a specific note

You can retrieve a list of resources that are associated with a specific note ID. For example, you can list images with a specific CVE vulnerability.

To list all images within a project that are associated with a particular note, use the following filter expression:

noteProjectId="PROVIDER_PROJECT_ID" AND noteId="NOTE_ID"

To check a specific image for a specific note, use the following filter expression:

resourceUrl="RESOURCE_URL" AND noteProjectId="PROVIDER_PROJECT_ID" \
    AND noteId="NOTE_ID"

Where:

• PROVIDER_PROJECT_ID is the ID of the provider project. For example, goog-vulnz provides the default vulnerability analysis.
• NOTE_ID is the ID of the note. Security related notes are often formatted as CVE-2019-12345.
• RESOURCE_URL is the complete URL of the image https://HOSTNAME/PROJECT_ID/IMAGE_ID@sha256:HASH

For example, to check for all images that have an occurrence of CVE-2017-16231 as analyzed by Google, use the following filter expression:

noteProjectId="goog-vulnz" AND noteId="CVE-2017-16231"
