Detective Client - AWS SDK for JavaScript v3

@aws-sdk/client-detective

NPM version NPM downloads

Description

AWS SDK for JavaScript Detective Client for Node.js, Browser and React Native.

Detective uses machine learning and purpose-built visualizations to help you to analyze and investigate security issues across your Amazon Web Services (Amazon Web Services) workloads. Detective automatically extracts time-based events such as login attempts, API calls, and network traffic from CloudTrail and Amazon Virtual Private Cloud (Amazon VPC) flow logs. It also extracts findings detected by Amazon GuardDuty.

The Detective API primarily supports the creation and management of behavior graphs. A behavior graph contains the extracted data from a set of member accounts, and is created and managed by an administrator account.

To add a member account to the behavior graph, the administrator account sends an invitation to the account. When the account accepts the invitation, it becomes a member account in the behavior graph.

Detective is also integrated with Organizations. The organization management account designates the Detective administrator account for the organization. That account becomes the administrator account for the organization behavior graph. The Detective administrator account is also the delegated administrator account for Detective in Organizations.

The Detective administrator account can enable any organization account as a member account in the organization behavior graph. The organization accounts do not receive invitations. The Detective administrator account can also invite other accounts to the organization behavior graph.

Every behavior graph is specific to a Region. You can only use the API to manage behavior graphs that belong to the Region that is associated with the currently selected endpoint.

The administrator account for a behavior graph can use the Detective API to do the following:

  • Enable and disable Detective. Enabling Detective creates a new behavior graph.

  • View the list of member accounts in a behavior graph.

  • Add member accounts to a behavior graph.

  • Remove member accounts from a behavior graph.

  • Apply tags to a behavior graph.

The organization management account can use the Detective API to select the delegated administrator for Detective.

The Detective administrator account for an organization can use the Detective API to do the following:

  • Perform all of the functions of an administrator account.

  • Determine whether to automatically enable new organization accounts as member accounts in the organization behavior graph.

An invited member account can use the Detective API to do the following:

  • View the list of behavior graphs that they are invited to.

  • Accept an invitation to contribute to a behavior graph.

  • Decline an invitation to contribute to a behavior graph.

  • Remove their account from a behavior graph.

All API actions are logged as CloudTrail events. See Logging Detective API Calls with CloudTrail.

We replaced the term "master account" with the term "administrator account." An administrator account is used to centrally manage multiple accounts. In the case of Detective, the administrator account manages the accounts in their behavior graph.

Installing

To install the this package, simply type add or install @aws-sdk/client-detective using your favorite package manager:

  • npm install @aws-sdk/client-detective
  • yarn add @aws-sdk/client-detective
  • pnpm add @aws-sdk/client-detective

Getting Started

Import

The AWS SDK is modulized by clients and commands. To send a request, you only need to import the DetectiveClient and the commands you need, for example AcceptInvitationCommand:

// ES5 example
const { DetectiveClient, AcceptInvitationCommand } = require("@aws-sdk/client-detective");
// ES6+ example
import { DetectiveClient, AcceptInvitationCommand } from "@aws-sdk/client-detective";

Usage

To send a request, you:

  • Initiate client with configuration (e.g. credentials, region).
  • Initiate command with input parameters.
  • Call send operation on client with command object as input.
  • If you are using a custom http handler, you may call destroy() to close open connections.
// a client can be shared by different commands.
const client = new DetectiveClient({ region: "REGION" });

const params = {
  /** input parameters */
};
const command = new AcceptInvitationCommand(params);

Async/await

We recommend using await operator to wait for the promise returned by send operation as follows:

// async/await.
try {
  const data = await client.send(command);
  // process data.
} catch (error) {
  // error handling.
} finally {
  // finally.
}

Async-await is clean, concise, intuitive, easy to debug and has better error handling as compared to using Promise chains or callbacks.

Promises

You can also use Promise chaining to execute send operation.

client.send(command).then(
  (data) => {
    // process data.
  },
  (error) => {
    // error handling.
  }
);

Promises can also be called using .catch() and .finally() as follows:

client
  .send(command)
  .then((data) => {
    // process data.
  })
  .catch((error) => {
    // error handling.
  })
  .finally(() => {
    // finally.
  });

Callbacks

We do not recommend using callbacks because of callback hell, but they are supported by the send operation.

// callbacks.
client.send(command, (err, data) => {
  // process err and data.
});

v2 compatible style

The client can also send requests using v2 compatible style. However, it results in a bigger bundle size and may be dropped in next major version. More details in the blog post on modular packages in AWS SDK for JavaScript

import * as AWS from "@aws-sdk/client-detective";
const client = new AWS.Detective({ region: "REGION" });

// async/await.
try {
  const data = await client.acceptInvitation(params);
  // process data.
} catch (error) {
  // error handling.
}

// Promises.
client
  .acceptInvitation(params)
  .then((data) => {
    // process data.
  })
  .catch((error) => {
    // error handling.
  });

// callbacks.
client.acceptInvitation(params, (err, data) => {
  // process err and data.
});

Troubleshooting

When the service returns an exception, the error will include the exception information, as well as response metadata (e.g. request id).

try {
  const data = await client.send(command);
  // process data.
} catch (error) {
  const { requestId, cfId, extendedRequestId } = error.$$metadata;
  console.log({ requestId, cfId, extendedRequestId });
  /**
   * The keys within exceptions are also parsed.
   * You can access them by specifying exception names:
   * if (error.name === 'SomeServiceException') {
   *     const value = error.specialKeyInException;
   * }
   */
}
