Managing security sources using the Security Command Center API

This guide walks you through using the Security Command Center API to create a source to generate findings. When you add a source, Security Command Center creates appropriate sources and assigns them the relevant permissions.

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.

Before you begin

Before you set up a source, you need to authenticate with the Security Command Center API.

Creating a source

This example shows how to create a source with a specific display name and description that is used in Security Command Center.

The server automatically assigns an ID to the source.

REST

In the API, make a request to the organizations.sources.create method. The request body contains an instance of Source.

  POST https://securitycenter.googleapis.com/v2/organizations/ORGANIZATION_ID/sources

  {
    "name": "SOURCE_NAME",
    "description": "SOURCE_DESCRIPTION",
    "displayName": "DISPLAY_NAME"
  }

Replace the following:

  • ORGANIZATION_ID: your organization ID.
  • SOURCE_NAME: the name of the source.
  • SOURCE_DESCRIPTION: a description of the source (max: 1,024 characters).
  • DISPLAY_NAME: the display name of the source (between one and 64 characters).

Go

	"context"
	"fmt"
	"io"

	securitycenter "cloud.google.com/go/securitycenter/apiv2"
	"cloud.google.com/go/securitycenter/apiv2/securitycenterpb"
)

// createSource creates a new source for organization orgID. orgID is
// the numeric identifier of the organization
func createSource(w io.Writer, orgID string) error {
	// orgID := "12321311"
	// Instantiate a context and a security service client to make API calls.
	ctx := context.Background()
	client, err := securitycenter.NewClient(ctx)
	if err != nil {
		return fmt.Errorf("securitycenter.NewClient: %w", err)
	}
	defer client.Close() // Closing the client safely cleans up background resources.

	req := &securitycenterpb.CreateSourceRequest{
		Source: &securitycenterpb.Source{
			DisplayName: "Customized Display Name",
			Description: "A new custom source that does X",
		},
		Parent: fmt.Sprintf("organizations/%s", orgID),
	}
	source, err := client.CreateSource(ctx, req)
	if err != nil {

The source is not visible in the Security Command Center console until it generates findings. You can verify it was created by following the instructions in Get a specific source.

Updating a source

You can update a source's display name and description after it's created. You can also use a field mask to update only one field. The example below uses a field mask to only update the display name, leaving the description unchanged.

REST

In the API, make a request to the organizations.sources.patch method. The request body contains an instance of Source.

  PATCH https://securitycenter.googleapis.com/v2/organizations/ORGANIZATION_ID/sources/SOURCE_ID?updateMask=displayName -d

  {
    "description": "SOURCE_DESCRIPTION",
    "displayName": "DISPLAY_NAME",
  }

Replace the following:

  • ORGANIZATION_ID: your organization ID.
  • SOURCE_ID: the source ID; to learn how to find a source ID, see Getting the source ID.
  • SOURCE_DESCRIPTION: a description of the source (max: 1024 characters).
  • DISPLAY_NAME: the display name of the source (between one and 64 characters).
