Rule: All S3 Buckets Logging S3 Data Events in CloudTrail
This rule ensures all S3 buckets are logging S3 data events in CloudTrail for enhanced cybersecurity control.
| Rule | All S3 buckets should log S3 data events in CloudTrail |
| Framework | Federal Financial Institutions Examination Council (FFIEC) |
| Severity | ✔ Medium |
Rule Description
This rule states that all S3 buckets must have logging enabled for S3 data events in CloudTrail specifically for Federal Financial Institutions Examination Council (FFIEC) compliance. CloudTrail provides visibility into actions taken on S3 buckets, and by enabling logging for S3 data events, it ensures that any activities related to data access, modification, or deletion are captured for auditing purposes.
Troubleshooting Steps
If logging for S3 data events in CloudTrail is not enabled for FFIEC compliance, follow these troubleshooting steps:
- 1.
Step 1: Verify the S3 bucket name: Confirm the name of the S3 bucket that needs to have logging enabled for FFIEC compliance.
- 2.
Step 2: Check CloudTrail configuration: Ensure that CloudTrail is properly set up and configured in your AWS account. Check if the necessary trail and its related parameters are defined correctly.
- 3.
Step 3: Verify IAM permissions: Confirm that the IAM role associated with CloudTrail has the necessary permissions to write logs to the S3 bucket. Ensure that the IAM policy attached to the role allows the
action on the target bucket.s3:PutObject - 4.
Step 4: Verify S3 bucket policy: Check the bucket policy of the S3 bucket and make sure it allows CloudTrail to write logs. Ensure that the policy includes the necessary statements to grant CloudTrail the required permissions.
- 5.
Step 5: Double-check FFIEC compliance: Ensure that the AWS environment complies with the relevant FFIEC regulations. Confirm the specific requirements related to S3 bucket logging.
- 6.
Step 6: Review CloudTrail event selectors: Confirm that the correct event selectors are set up for logging S3 data events in the CloudTrail trail. Make sure the appropriate filters are applied to capture the desired activities.
Necessary Codes
No specific codes are required for this rule. However, you may need to use AWS CLI commands to enable S3 bucket logging and configure CloudTrail.
Step-by-Step Guide
To remediate the issue and enable logging of S3 data events in CloudTrail for FFIEC compliance, follow these step-by-step instructions:
- 1.
Step 1: Log in to the AWS Management Console.
- 2.
Step 2: Open the CloudTrail service.
- 3.
Step 3: Select the appropriate CloudTrail trail for the target AWS account.
- 4.
Step 4: Click on the "Edit" button or the trail name itself to access the trail settings.
- 5.
Step 5: Scroll down to the "Data events" section and click on the "Add data event" button.
- 6.
Step 6: In the "Add data event" dialog box, select the desired S3 bucket from the dropdown menu.
- 7.
Step 7: Choose the specific S3 data events that need to be logged as per the FFIEC requirements.
- 8.
Step 8: Click on the "Save" or "Apply" button to save the changes.
- 9.
Step 9: Verify that the CloudTrail trail successfully logs S3 data events for the specified bucket.
- 10.
Step 10: Repeat the above steps for any additional S3 buckets that require logging for FFIEC compliance.
By following the above steps, you should be able to enable S3 bucket logging for data events in CloudTrail and ensure compliance with FFIEC requirements.
