Security Command Center API を使用したセキュリティ ソースの管理

このガイドでは、Security Command Center API を使用して検出結果を作成するためのソースを作成する方法について説明します。ソースを追加すると、Security Command Center によって適切なソースが作成され、そのソースに関連する権限が付与されます。

Security Command Center の IAM ロールは、組織レベル、フォルダレベル、またはプロジェクト レベルで付与できます。検出結果、アセット、セキュリティ ソースを表示、編集、作成、更新する権限は、アクセス権が付与されているレベルによって異なります。Security Command Center のロールの詳細については、アクセス制御をご覧ください。

始める前に

ソースを設定する前に、Security Command Center API で認証する必要があります。

ソースの作成

この例は、Security Command Center で使用される特定の表示名と説明を使用してソースを作成する方法を示しています。

サーバーでソースに自動的に ID が割り当てられます。

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 = f"organizations/{organization_id}"

created = client.create_source(
    request={
        "parent": org_name,
        "source": {
            "display_name": "Customized Display Name",
            "description": "A new custom source that does X",
        },
    }
)
print(f"Created Source: {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"
	"cloud.google.com/go/securitycenter/apiv1/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 {
		return fmt.Errorf("CreateSource: %w", err)
	}

	fmt.Fprintf(w, "New source created: %s\n", source.Name)
	fmt.Fprintf(w, "Display Name: %s\n", source.DisplayName)
	return nil
}

Node.js

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

// Creates a new client.
const client = new SecurityCenterClient();
// organizationId is numeric organization identifier.
/*
 * TODO(developer): Uncomment the following lines
 */
// const organizationId = "1234567777";
async function createSource() {
  const [source] = await client.createSource({
    source: {
      displayName: 'Customized Display Name',
      description: 'A new custom source that does X',
    },
    parent: client.organizationPath(organizationId),
  });
  console.log('New Source: %j', source);
}
createSource();

API

API で、organizations.sources.create メソッドに対するリクエストを行います。リクエストの本文には Source のインスタンスが含まれます。

  POST https://securitycenter.googleapis.com/API_VERSION/organizations/ORGANIZATION_ID/sources -d

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

以下を置き換えます。

  • API_VERSION: ターゲットとする API のバージョン。
  • ORGANIZATION_ID: 組織 ID。
  • SOURCE_NAME: ソースの名前。
  • SOURCE_DESCRIPTION: ソースの説明(最大 1,024 文字)。
  • DISPLAY_NAME: ソースの表示名(1~64 文字)。

検出結果が生成されるまで、Security Command Center コンソールにソースは表示されません。特定のソースの取得の手順に沿って、作成されたことを確認できます。

ソースの更新

ソースの表示名と説明は作成後に更新できます。また、フィールド マスクを使用して、更新するフィールドを 1 つのみにすることもできます。次の例では、フィールド マスクを使用して表示名のみを更新し、説明は変更していません。

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(
    request={
        "source": {"name": source_name, "display_name": "Updated Display Name"},
        "update_mask": field_mask,
    }
)
print(f"Updated Source: {updated}")

Java

  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.Builder request =
        UpdateSourceRequest.newBuilder().setSource(source).setUpdateMask(updateMask);

    // Call the API.
    Source response = client.updateSource(request.build());

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

API

API で、organizations.sources.patch メソッドに対するリクエストを行います。リクエストの本文には Source のインスタンスが含まれます。

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

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

以下を置き換えます。

  • API_VERSION: ターゲットとする API のバージョン。
  • ORGANIZATION_ID: 組織 ID。
  • SOURCE_ID: ソース ID。ソース ID を取得する手順については、ソース ID の取得をご覧ください。
  • SOURCE_DESCRIPTION: ソースの説明(最大 1,024 文字)。

特定のソースの取得

ソースの絶対リソース名を指定して Security Command Center にクエリすることで、ソースが正しく作成または更新されたことを確認します。

  # Note: For GCloud you can use either full resource name or just ID Flags.
  # In this example, we are using ID Flags.

ソースの一覧表示

Security Command Center を使用すると、特定のソースを一覧表示することや、組織で現在使用可能なすべてのソースを一覧表示できます。

Python

# Call the API and print out each existing source.
for i, source in enumerate(client.list_sources(request={"parent": parent})):
    print(i, source)

Java
