Collect AWS CloudWatch logs

Supported in:

This document explains how to ingest AWS CloudWatch logs to Google Security Operations using Amazon S3 or Amazon Kinesis Data Firehose. AWS CloudWatch is a monitoring and observability service, which collects operational data in the form of logs, metrics, and events. This integration lets you send these logs to Google SecOps for analysis and monitoring.

Before you begin

Make sure you have the following prerequisites:

  • Google SecOps instance
  • Privileged access to AWS

Configure CloudWatch logs export using AWS S3

This export process is required to be done regularly, in order to get the latest CloudWatch logs ingested into S3.

Create an Amazon S3 bucket

We recommend to use a bucket that was created specifically for CloudWatch logs.

  1. Open the Amazon S3 console .
  2. If required, you can change the Region.
    • On the navigation bar, select the Regionwhere your CloudWatch Logsreside.
  3. Click Create Bucket.
    • Bucket Name: enter a meaningful name for the bucket.
    • Region: select the region where your CloudWatch Logs data resides.
    • Click Create.

Create an IAM user with full access to Amazon S3 and CloudWatch Logs

  1. Open the IAM console .
  2. Click Users > Create user.
  3. Enter a name in the User namefield (for example, CWExport ).
  4. Select both Programmatic accessand AWS Management Console access.
  5. Select either Autogenerated passwordor Custom password.
  6. Click Next: Permissions.
  7. Choose Attach existing policies directly.
  8. Search for and select the AmazonS3FullAccessand CloudWatchLogsFullAccesspolicies to the user.
  9. Click Next: Tags.
  10. Click Next: Review.
  11. Click Create user.

Configure permissions on Amazon S3 bucket

  1. In the Amazon S3 console, choose the bucket that you previously created.
  2. Click Permissions > Bucket policy.
  3. In the Bucket Policy Editor, add the following policy.
