Code sample

Go

import (
	"context"
	"fmt"
	"io"

	securitycenter "cloud.google.com/go/securitycenter/apiv1"
	iam "google.golang.org/genproto/googleapis/iam/v1"
)

// getSourceIamPolicy prints the policy for sourceName to w and return it.
// sourceName is the full resource name of the source with the policy of interest.
func getSourceIamPolicy(w io.Writer, sourceName string) error {
	// sourceName := "organizations/111122222444/sources/1234"
	// 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 := &iam.GetIamPolicyRequest{
		Resource: sourceName,
	}

	policy, err := client.GetIamPolicy(ctx, req)
	if err != nil {
		return fmt.Errorf("GetIamPolicy(%s): %v", sourceName, err)
	}

	fmt.Fprintf(w, "Policy: %v", policy)
	return nil
}

Java

static Policy getIamPolicySource(SourceName sourceName) {
  try (SecurityCenterClient client = SecurityCenterClient.create()) {
    // Start setting up a request to get IAM policy for a source.
    // SourceName sourceName = SourceName.of(/*organization=*/"123234324",/*source=*/
    // "423432321");
    GetIamPolicyRequest request =
        GetIamPolicyRequest.newBuilder().setResource(sourceName.toString()).build();

    // Call the API.
    Policy response = client.getIamPolicy(request);

    System.out.println("Policy: " + response);
    return response;
  } catch (IOException e) {
    throw new RuntimeException("Couldn't create client.", e);
  }
}

Node.js

// Imports the Google Cloud client library.
const {SecurityCenterClient} = require('@google-cloud/security-center');

// Creates a new client.
const client = new SecurityCenterClient();

async function getSourceIamPolicy() {
  // sourceName is the full resource name to retrieve the policy for.
  /*
   * TODO(developer): Uncomment the following lines
   */
  // const sourceName = "organizations/111122222444/sources/1234";

  const [existingPolicy] = await client.getIamPolicy({
    resource: sourceName,
  });

  console.log('Current policy: %j', existingPolicy);
}
getSourceIamPolicy();

Python

from google.cloud import securitycenter

client = securitycenter.SecurityCenterClient()

# 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"
# Get the old policy so we can do an incremental update.
policy = client.get_iam_policy(request={"resource": source_name})
print("Policy: {}".format(policy))
