This guide walks you through using the Security Command Center (Security Command Center) API to create a source for an organization to generate findings. When you add a source, Security Command Center will create appropriate sources and assign them the relevant permissions.
Before you begin
Before you set up a source, you'll need to complete the following:
Creating a source
This example shows to create a source with a specific display name and description that will be used in the Security Command Center dashboard.
The source's ID is automatically assigned by the server.
Python
from google.cloud import securitycenter
client = securitycenter.SecurityCenterClient()
# organization_id is the numeric ID of the organization. e.g.:
# organization_id = "111122222444"
org_name = "organizations/{org_id}".format(org_id=organization_id)
created = client.create_source(
org_name,
{
"display_name": "Customized Display Name",
"description": "A new custom source that does X",
},
)
print("Created Source: {}".format(created.name))Java
static Source createSource(OrganizationName organizationName) {
try (SecurityCenterClient client = SecurityCenterClient.create()) {
// Start setting up a request to create a source in an organization.
// OrganizationName organizationName = OrganizationName.of(/*organizationId=*/"123234324");
Source source =
Source.newBuilder()
.setDisplayName("Customized Display Name")
.setDescription("A new custom source that does X")
.build();
CreateSourceRequest.Builder request =
CreateSourceRequest.newBuilder().setParent(organizationName.toString()).setSource(source);
// Call the API.
Source response = client.createSource(request.build());
System.out.println("Created Source: " + response);
return response;
} catch (IOException e) {
throw new RuntimeException("Couldn't create client.", e);
}
}Go
import (
"context"
"fmt"
"io"
securitycenter "cloud.google.com/go/securitycenter/apiv1"
securitycenterpb "google.golang.org/genproto/googleapis/cloud/securitycenter/v1"
)
// 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: %v", 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)

description: 'A new custom source that does X',
},

});
console.log('New Source: %j', source);
}
createSource();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.
Python
from google.cloud import securitycenter
from google.protobuf import field_mask_pb2
client = securitycenter.SecurityCenterClient()
# Field mask to only update the display name.
field_mask = field_mask_pb2.FieldMask(paths=["display_name"])
# source_name is the resource path for a source that has been
# created previously (you can use list_sources to find a specific one).
# Its format is:
# source_name = "organizations/{organization_id}/sources/{source_id}"
# e.g.:
# source_name = "organizations/111122222444/sources/1234"
updated = client.update_source(
{"name": source_name, "display_name": "Updated Display Name"},
update_mask=field_mask,
)
print("Updated Source: {}".format(updated))Java
static Source updateSource(SourceName sourceName) {
try (SecurityCenterClient client = SecurityCenterClient.create()) {
// Start setting up a request to update a source.
// SourceName sourceName = SourceName.of(/*organization=*/"123234324",/*source=*/
// "423432321");
Source source =
Source.newBuilder()
.setDisplayName("Updated Display Name")
.setName(sourceName.toString())
.build();
FieldMask updateMask = FieldMask.newBuilder().addPaths("display_name").build();

UpdateSourceRequest.newBuilder().setSource(source).setUpdateMask(updateMask);
// Call the API.

updateSource();Setting Cloud IAM policies on a source
After you create a source, update the Cloud Identity and Access Management (Cloud IAM) policies to allow
Python

You can verify that a source was created or updated appropriately by querying Security Command Center with the source's absolute resource name:
gcloud
# Note: For GCloud you can use either full resource name or just ID Flags. # In this example, we are using ID Flags. # ORGANIZATION_ID=12344321 # SOURCE_ID=43211234 gcloud alpha scc sources describe $ORGANIZATION_ID --source=$SOURCE_ID
For more examples, run:
