CloudTrail

Overview

AWS CloudTrail is a service that enables governance, compliance, and operational and risk auditing of your AWS account. With CloudTrail, you can log, continuously monitor, and retain account activity related to actions across your AWS infrastructure. CloudTrail provides the event history of your AWS account activity, including actions taken through the AWS Management Console, AWS SDKs, command line tools, and other AWS services (source: AWS CloudTrail Overview).

The following Sekoia.io built-in rules match the intake AWS CloudTrail. This documentation is updated automatically and is based solely on the fields used by the intake which are checked against our rules. This means that some rules will be listed but might not be relevant with the intake.

  • Effort: master
TOR Usage Generic Rule

Detects TOR usage globally, whether the IP is a destination or source. TOR is short for The Onion Router, and it gets its name from how it works. TOR intercepts the network traffic from one or more apps on user’s computer, usually the user web browser, and shuffles it through a number of randomly-chosen computers before passing it on to its destination. This disguises user location, and makes it harder for servers to pick him/her out on repeat visits, or to tie together separate visits to different sites, this making tracking and surveillance more difficult. Before a network packet starts its journey, user’s computer chooses a random list of relays and repeatedly encrypts the data in multiple layers, like an onion. Each relay knows only enough to strip off the outermost layer of encryption, before passing what’s left on to the next relay in the list.

  • Effort: master

Deploying the Data Collection Architecture

This section will guide you through creating all the AWS resources needed to collect AWS logs. If you already have existing resources that you want to use, you may do so, but any potential issues or incompatibilities with this tutorial will be your responsibility.

Prerequisites

In order to set up the AWS architecture, you need an administator access to the Amazon console with the permissions to create and manage S3 buckets, SQS queues, S3 notifications and users.

To get started, click on the button below and fill the form on AWS to set up the required environment for Sekoia Deploy to AWS

You need to fill 4 inputs:

  • Stack name - Name of the stack in CloudFormation (Name of the template)
  • BucketName - Name of the S3 Bucket
  • IAMUserName - Name of the dedicated user to access the S3 and SQS queue
  • SQSName - Name of the SQS queue

Read the different pages and click on Next, then click on Submit.

You can follow the creation in the Events tab (it can take few minutes).

Once finished, it should be displayed on the left CREATE_COMPLETE. Click on the Outputs tab in order to retrieve the information needed for Sekoia playbook.

Create a S3 Bucket

Please refer to this guide to create a S3 Bucket.

Create a SQS queue

The collect will rely on S3 Event Notifications (SQS) to get new S3 objects.

  1. Create a queue in the SQS service by following this guide
  2. In the Access Policy step, choose the advanced configuration and adapt this configuration sample with your own SQS Amazon Resource Name (ARN) (the main change is the Service directive allowing S3 bucket access):
    {
      "Version": "2008-10-17",
      "Id": "__default_policy_ID",
      "Statement": [
        {
          "Sid": "__owner_statement",
          "Effect": "Allow",
          "Principal": {
            "Service": "s3.amazonaws.com"
          },
          "Action": "SQS:SendMessage",
          "Resource": "arn:aws:sqs:XXX:XXX"
        }
      ]
    }
    

Important

Keep in mind that you have to create the SQS queue in the same region as the S3 bucket you want to watch.

Create a S3 Event Notification

Use the following guide to create S3 Event Notification. Once created:

  1. Select the notification for object creation in the Event type section
  2. As the destination, choose the SQS service
  3. Select the queue you created in the previous section

CloudTrail trail

To allow Cloudtrail to store logs in S3, you have to create an AWS S3 Policy. Follow this guide to edit your S3 Bucket.

For CloudTrail to record activities across your desired AWS services, you need an active CloudTrail trail.

To configure your trail:

  1. In the AWS console, navigate to: Services > CloudTrail > Trails.
  2. Activate the specific events you want to log:

  3. Management events: provide visibility into management operations that are performed on resources in your AWS account.

  4. Insights events: help AWS users identify and respond to unusual activity associated with write API calls by continuously analyzing CloudTrail management events. Insights events are logged when CloudTrail detects unusual write management API activity in your account.
  5. Data events: provide visibility into the resource operations performed on or within a resource.

Activate the logging on the trail through the switch button (On/Off) located at the top right corner of the trail page.

Create the intake

Go to the intake page and create a new intake from the AWS CloudTrail format.

Pull events

Go to the playbook page and create a new playbook with the Fetch new CloudTrail records on S3 connector.

Set up the module configuration with the AWS Access Key, the secret key, and the region name. Set up the trigger configuration with the name of the SQS queue and the intake key from the previously created intake.

Important

In the "Trigger Configuration" settings of your Cloudtrail playbook, we recommend using the following configuration by default: chunk_size = 10000, frequency = 10 and tick the box "delete_consumed_messages" that will delete S3 notifications of your Amazon Simple Queue Service to avoid duplicates.

Start the playbook and enjoy your events.
