AWS CloudTrail

Overview

See AWS Configuration for Cloud SIEM if you are setting up AWS CloudTrail for Cloud SIEM.

AWS CloudTrail provides an audit trail for your AWS account. Datadog reads this audit trail and creates events. Search your Datadog events explorer for these events or use them for correlation on your dashboards. Here is an example of a CloudTrail event:

For information on other AWS services, see the Amazon Web Services integration page

Setup

Installation

If you haven’t already, set up the Amazon Web Services integration first.

Event collection

Note: The Datadog CloudTrail integration requires events to be collected in a CloudTrail bucket.

Add the following permissions to your Datadog IAM policy to collect AWS CloudTrail events. For more information on CloudTrail policies, see the AWS CloudTrail API Reference. CloudTrail also requires some S3 permissions to access the trails. These are required on the CloudTrail bucket only. For more information on Amazon S3 policies, see the Amazon S3 API Reference.

AWS Permission	Description
`cloudtrail:DescribeTrails`	Lists trails and the s3 bucket the trails are stored in.
`cloudtrail:GetTrailStatus`	Skips inactive trails.
`s3:ListBucket`	Lists objects in the CloudTrail bucket to get available trails.
`s3:GetBucketLocation`	Obtains the bucket’s region to download trails.
`s3:GetObject`	Fetches available trails.
`organizations:DescribeOrganization`	Returns information about an account’s organization (required for org trails).

Add this policy to your existing main Datadog IAM policy:

{
    "Sid": "AWSDatadogPermissionsForCloudtrail",
    "Effect": "Allow",
    "Principal": {
        "AWS": "<ARN_FROM_MAIN_AWS_INTEGRATION_SETUP>"
    },
    "Action": ["s3:ListBucket", "s3:GetBucketLocation", "s3:GetObject"],
    "Resource": [
        "arn:aws:s3:::<YOUR_S3_CLOUDTRAIL_BUCKET_NAME>",
        "arn:aws:s3:::<YOUR_S3_CLOUDTRAIL_BUCKET_NAME>/*"
    ]
}

Note: The principal ARN is the one listed during the installation process for the main AWS integration. See the Resources section of How AWS CloudTrail works with IAM for more information on CloudTrail resource ARNs. If you are updating your policy (as opposed to adding a new one), you don’t need the SID or the Principal.

Install the Datadog - AWS CloudTrail integration: On the integration page, choose the types of events to show as normal priority (the default filter) in the Datadog events explorer. The accounts you configured in the Amazon Web Services page are also shown here. If you would like to see other events that are not mentioned here, contact Datadog support.

Log collection

Enable logging

In AWS CloudTrail, create a Trail and select an S3 bucket to write the logs in.

Send logs to Datadog

If you haven’t already, set up the Datadog Forwarder Lambda function in your AWS account.
Once set up, go to the Datadog Forwarder Lambda function. In the Function Overview section, click Add Trigger.
Select the S3 trigger for the Trigger Configuration.
Select the S3 bucket that contains your CloudTrail logs.
Leave the event type as All object create events.
Click Add to add the trigger to your Lambda.

Go to the Log Explorer to start exploring your logs.

For more information on collecting AWS Services logs, see Send AWS Services Logs with the Datadog Lambda Function.

The AWS CloudTrail integration creates many different events based on the AWS CloudTrail audit trail. All events are tagged with #cloudtrail in your Datadog events explorer. You can set their priority in the integration configuration.

CloudTrail events that can be set to a normal priority (they appear in the Event Explorer under the default filter):

apigateway
autoscaling
cloudformation
cloudfront
cloudsearch
cloudtrail
codedeploy
codepipeline

Troubleshooting

The CloudTrail tile is missing or there are no accounts listed

You need to first configure the Amazon Web Services integration. Then the CloudTrail tile can be configured.
