Rule: All S3 Buckets Should Log S3 Data Events in CloudTrail

Rule Description:

Troubleshooting Steps:

2. 1.
   Ensure that the IAM user or role used to enable CloudTrail and S3 logging has sufficient permissions. It should have permissions to create and update CloudTrail configurations and access S3 buckets.
4. 2.
   Verify that the S3 bucket to be configured for logging is accessible and properly configured. Make sure the bucket exists and the appropriate permissions are set.
6. 3.
   Check if there are any conflicting IAM policies or bucket policies that may prevent CloudTrail from logging S3 data events.
8. 4.
   Ensure that the CloudTrail service is enabled in your AWS account.

Step-by-step Remediation:

Using AWS Management Console:

2. 1.
   Sign in to the AWS Management Console.
4. 2.
   Go to the CloudTrail console.
6. 3.
   Create a new trail or select an existing trail.
8. 4.
   On the Trail details page, select the S3 bucket where the CloudTrail logs should be stored. This bucket should be different from the S3 buckets you want to monitor.
10. 5.
    Enable logging of Data Events in the CloudTrail configuration for the chosen trail.
12. 6.
    Choose the specific S3 bucket(s) to log data events for.
14. 7.
    Review other settings such as storage options, log file validation, and encryption, based on your requirements.
16. 8.
    Confirm and create the trail.

Using AWS CLI:

2. 1.

   Open the AWS CLI or terminal.

4. 2.

   Run the following command to create a trail with S3 logging:

   $ aws cloudtrail create-trail --name my-trail --s3-bucket-name my-bucket --include-global-service-events --is-multi-region-trail --enable-log-file-validation --enable-cloud-watch-logs-exports 'CloudWatchLogsLogGroupArn=my-log-group-arn'
   

   Adjust the values for

   --name

   ,

   --s3-bucket-name

   , and

   --enable-cloud-watch-logs-exports

   as per your requirements.

6. 3.

   To enable logging of specific S3 buckets, run the following command:

   $ aws cloudtrail put-event-selectors --trail-name my-trail --event-selectors '[{"ReadWriteType": "All", "IncludeManagementEvents": true, "DataResources": [{"Type": "AWS::S3::Object", "Values": ["arn:aws:s3:::my-bucket"]}]}]'
   

   Replace

   my-trail

   with the appropriate trail name and

   my-bucket

   with the desired S3 bucket.

8. 4.

   Review other settings such as storage options, log file validation, and encryption using separate CLI commands as per your requirements.
