Overview

Amazon Security Lake is a security data lake for aggregating and managing security log and event data.

This integration ingests security logs stored in Amazon Security Lake into Datadog for further investigation and real-time threat detection. To learn more about Amazon Security Lake, visit the Amazon Security Lake user guide in AWS.

Setup

Prerequisites

Amazon Security Lake must be configured for your AWS account or AWS organization. See the Amazon Security Lake user guide for more details.
You must have a Datadog account that is using both Datadog Log Management and Datadog Cloud SIEM.
If you haven’t already, set up the Amazon Web Services integration for the AWS account where Amazon Security Lake is storing data.

Note: If you only want to integrate this AWS Account to use the Amazon Security Lake integration, you can disable metric collection in the AWS integration page so that Datadog doesn’t monitor your AWS infrastructure and you are not billed for Infrastructure Monitoring.

Log collection

Add the following IAM policy to your existing DatadogIntegrationRole IAM role so that Datadog can ingest new log files added to your security lake.

{
  "Version": "2012-10-17",
  "Statement": [
      {

          "Action": [
              "s3:GetObject"
          ],
          "Resource": "arn:aws:s3:::aws-security-data-lake-*"
      }
  ]
}
