Exporting Security Command Center data

This page describes two methods for exporting Security Command Center data, including assets, findings, and security marks:

• One-time exports for current findings, assets, and security marks
• Continuous Exports that automatically export new findings to Pub/Sub

Security Command Center lets you export data using the Security Command Center API or the Google Cloud console.

Alternatively, you can export findings to BigQuery.

One-time exports

One-time exports let you manually transfer and download current and historical findings and assets. You can transfer data to a Cloud Storage bucket and download it to your local workstation. You can also export data to a CSV file.

Permissions

To perform one-time exports, you need the following:

• The Identity and Access Management (IAM) role Security Center Admin Viewer (roles/securitycenter.adminViewer), or any role that has the following permissions:

  • resourcemanager.organizations.get (required only for organization-level activations of Security Command Center)
  • resourcemanager.projects.get (required for project-level activations of Security Command Center)
  • securitycenter.assets.group
  • securitycenter.assets.list
  • securitycenter.findings.group
  • securitycenter.findings.list
  • securitycenter.sources.get
  • securitycenter.sources.list
  • securitycenter.userinterfacemetadata.get

• The Storage Admin role, which lets you store data in Cloud Storage buckets.

The IAM roles for Security Command Center can be granted at the organization, folder, or project level. Your ability to view, edit, create, or update findings, assets, and security sources depends on the level for which you are granted access. To learn more about Security Command Center roles, see Access control.

Export data using the Google Cloud console

Using the Google Cloud console, you can do the following:

• Export assets or findings to a Cloud Storage bucket
• Export findings to a CSV file

Export assets or findings to a Cloud Storage bucket

This section describes how to export Security Command Center data to a Cloud Storage bucket. When you click Export in the Security Command Center dashboard, Security Command Center automatically gets credentials or permissions to write to the Cloud Storage bucket.

Findings and assets are exported in separate operations. You can export a JSON or JSONL file to an existing Cloud Storage bucket or create one during the export process.

You can export all current assets or findings, or select the filters you want to use before you export.

1. Go to Security Command Center in the Google Cloud console.

   Go to Security Command Center

2. To export assets, click the Assets tab. For findings, click the Findings tab.

3. In the Filter field, select the attributes, properties, and security marks you want to use to filter your data. A blank filter is evaluated as a wildcard and all assets or findings are exported. For more information on creating filters, see Using the Security Command Center dashboard.

4. When you're done creating a filter, click Export, and then, under One-time, click Cloud Storage.

5. On the Export page, configure the export:

   1. On the Group Results By drop-down list, select how you want to group the export data.
   2. On the Format drop-down list, select JSON or JSONL.
   3. The Filters field displays the values for attributes in the filter. To change the filter, return to the Findings page.
   4. In the Display Results From box, select the timestamp of the data you want to export.
   5. In the Export to box, select the project where you want to export the data.
   6. In the Export Path box, click Browse.
   7. On the Select object panel, select an existing Cloud Storage bucket or create a storage bucket.
   8. After you select or create a bucket, under Filename, enter a name for the export file.
   9. Click Select.

6. When you're finished configuring the export, click Export.

   If you selected an existing file in the bucket, the Confirm Overwrite dialog displays.

   • To overwrite the existing file, click Confirm.
   • To change the file you're writing to, click Cancel, then click Browse in the Export Path box and select or create a different file.

The configured data is saved to the Cloud Storage bucket you specified.

Download exported data from a Cloud Storage bucket

To download the exported JSON or JSONL data, perform the following steps:

1. Go to the Storage browser page in the Google Cloud console.

   Go to Storage browser

2. Select your project, and then click the bucket to which you exported data.

3. Select the checkbox next to the export file, and then click Download.

4. On the Save File dialog, select the location where you want to save the file, and then click Save.

The JSON or JSONL file is downloaded to the location you specified.

Export findings to a CSV file

To configure the export, you can filter findings by category, severity, and other properties. All findings that match the filter are included in the CSV file. You can export up to 3,500,000 findings at a time.

The finding records are exported with a default set of columns, which might not match what you see in the Google Cloud console. That is, hiding or unhiding columns using the Column display options doesn't change which columns are exported. Similarly, changing the Rows per page value has no effect on the exported content.

To export findings to a CSV file, perform the following steps:

1. On the Security Command Center page of the Google Cloud console, go to the Findings page.

   Go to Findings

2. On the toolbar, click the project selector, and select your project, folder, or organization.

   To use this feature, you must be on the redesigned Findings page. For more information, see Upgrade to the Findings Workflow Improvements.

3. Optional: To narrow down the findings to be exported, apply a filter.

4. Click Export, and click CSV. Security Command Center begins exporting the findings.

   When the export is complete, a notification appears on the toolbar.

5. On the toolbar, click the notification icon.

6. On the Saved export as CSV notification, click Download. The CSV file is downloaded to your local workstation.

Export data using the Security Command Center API

You can export assets, findings, and security marks to a Cloud Storage bucket or your local workstation by using the Security Command Center API. Follow the guides for listing security findings or listing assets. Once listed, the API responses for findings or assets can be downloaded or exported.

To list findings or assets, with any attached security marks, you can use the following API methods:

• organizations.sources.findings/list
• organizations.assets/list
• folders.sources.findings/list
• folders.assets/list
• project.sources.findings/list
• project.assets/list

The methods return assets or findings with their full set of properties, attributes, and associated marks in JSON format. If your application requires data to be in a different format, you need to write custom code to convert the JSON output.

If you specify a value in the groupBy field, you can use the following methods:

• organizations.assets/group
• organizations.sources.findings/group
• folders.sources.findings/list
• folders.assets/list
• projects.assets/group
• projects.sources.findings/group

TheGroupAssets and GroupFindings methods return a list of an organization's assets or findings, grouped by specified properties.

To export API output to a Cloud Storage bucket, you can use Cloud Shell to list assets or findings. Then, write the output to a file, and then copy that file to your selected storage bucket.

1. Open Cloud Shell.

   Go to Cloud Shell

2. To write findings or assets to a file, add an output string to the gcloud CLI commands for listing findings or listing assets.

   For example, the following command stores listed findings in a text file named FINDINGS.txt.

    gcloud scc findings list PARENT_ID --source=SOURCE_ID \
      --filter="FILTER" > FINDINGS.txt
   

   Replace the following:

   • FILTER: An optional expression to limit the list of findings printed to those that match the filter expression.

   • PARENT_ID: the ID of any of the following parent resources:

     • Organization, specified as organizations/ORGANIZATION_ID or ORGANIZATION_ID
     • Folder, specified as folders/FOLDER_ID
     • Project, specified as projects/PROJECT_ID

   • SOURCE_ID: the source ID for the finding provider. To find a source ID, see Getting the source ID.

   • FINDINGS.txt: the name and extension of a target file to store the list of findings.

3. Copy FINDINGS.txt to your Cloud Storage bucket.

   gsutil cp FINDINGS.txt gs://BUCKET_NAME

   Replace BUCKET_NAME with the name of your bucket.

4. To save FINDINGS.txt to your local workstation instead of a Cloud Storage bucket, run the following command:

   cloudshell download FINDINGS.txt

Continuous Exports

Continuous Exports simplify the process of automatically exporting Security Command Center findings into Pub/Sub. When new findings are written, they are automatically exported to designated Pub/Sub topics in near-real time, letting you integrate them into your existing workflow.

To learn more about Pub/Sub, see What is Pub/Sub?

Continuous Exports versus finding notifications

Security Command Center lets you set up finding notifications for Pub/Sub using the Security Command Center API. The API requires you to use Google Cloud CLI to set up Pub/Sub topics, create finding filters, and create NotificationConfigs, files that contain configuration settings to send notifications. Continuous Exports offer the same functionality, but creating exports is simplified by using the Security Command Center dashboard.

Permissions

To create and manage continuous exports, you need one of the following roles.

• roles/securitycenter.adminEditor
• roles/securitycenter.adminViewer

You can also use any role that has the following permissions:

• To view or publish Pub/Sub topics:

  • pubsub.topics.publish
  • pubsub.topics.list

• To view the continuous exports page:

  • securitycenter.notificationconfig.get
  • securitycenter.notificationconfig.list

• To manage continuous exports:

  • securitycenter.notificationconfig.create
  • securitycenter.notificationconfig.update
  • securitycenter.notificationconfig.delete

To learn more about Security Command Center roles, see Access control.

Configuring Pub/Sub exports

Continuous Exports let you automate the export of all future findings to Pub/Sub or create filters to export future findings that meet specific criteria. You can filter findings by category, source, asset type, security marks, severity, state, and other variables.

Creating continuous exports

Your organization can create a maximum of 500 continuous exports.To create an export for Pub/Sub, do the following:

1. Go to the Security Command Center Findings page in the Google Cloud console.

   Go to Findings

2. In the Filter field, select the attributes, properties, or security marks you want to use to filter findings and enter desired variables. A blank filter is evaluated as a wildcard and all findings are exported. For more information on finding properties, see Using the Security Command Center dashboard.

3. Click Export, and then, under Continuous, click Pub/Sub.

4. Review your filter to ensure it's correct and, if necessary, return to the Findings page to modify it.

5. Under Continuous export name, enter a name for the export.

6. Under Continuous export description, enter a description for the export.

7. Under Export to, select a project for your export. You can't create a project on this page. To create a new project, see Creating a project.

8. Under Pub/Sub topic, select the topic where you want to export findings. To create a topic, do the following:

   1. Select Create a topic.
   2. Enter a Topic ID, and then select other options as needed:
      1. Learn about Creating and managing schemas.
      2. Learn about using customer-managed encryption keys (CMEK) with Pub/Sub.
   3. Click Create Topic.

9. Click Save. You see a confirmation and are returned to the findings page.

10. Follow the guide to create a subscription for your Pub/Sub topic.

The Pub/Sub export configuration is complete. To publish notifications, a service account is created for you in the form of [e-mail]. This service account is automatically granted the securitycenter.notificationServiceAgent role at the organization level. This service account role is required for notifications to function.
