Rule: CloudTrail Log File Validation Enabled
Ensure CloudTrail log file validation is enabled and operational.
| Rule | CloudTrail log file validation should be enabled |
| Framework | PCI v3.2.1 |
| Severity | ✔ Medium |
Rule Description:
This rule ensures that CloudTrail log file integrity validation is enabled for compliance with PCI (Payment Card Industry) version 3 requirements. Enabling log file validation helps to detect any unauthorized modifications or tampering of CloudTrail log files, ensuring the integrity and trustworthiness of the audit trails.
Enabling this feature allows you to regularly verify the integrity of your CloudTrail log files by checking the cryptographic hashes and signatures associated with each log file, thus providing an additional layer of security and protecting against potential data manipulation attempts.
Troubleshooting Steps:
- 1.Verify if AWS CloudTrail service is enabled in the AWS Management Console.
- 2.Check if you have sufficient permissions to enable CloudTrail log file validation.
- 3.Ensure that you are complying with the PCI v3 requirements regarding log file validation.
- 4.Check if the necessary AWS SDKs and software libraries are installed and up to date.
Necessary Codes:
There are no specific codes required for enabling CloudTrail log file validation. This is a configuration setting that can be updated through the AWS Management Console, AWS CLI, or AWS SDKs.
Step-by-Step Guide for Remediation:
Option 1: AWS Management Console
- 1.Open the AWS Management Console and navigate to the CloudTrail service.
- 2.Select the appropriate CloudTrail trail that needs log file validation enabled.
- 3.Click on the "Edit" button to modify the trail settings.
- 4.In the "Advanced" section, locate the "Log file integrity validation" option and enable it.
- 5.Click "Save" to apply the changes.
Option 2: AWS CLI
- 1.Install and configure the AWS CLI if not already done.
- 2.Open your preferred command-line interface.
- 3.Run the following command to enable log file integrity validation for the CloudTrail trail:
aws cloudtrail update-trail --name <trail_name> --enable-log-file-validation
Replace
with the name of your CloudTrail trail.<trail_name>
Option 3: AWS SDKs
- 1.Choose your preferred programming language and install the corresponding AWS SDK.
- 2.Configure the necessary credentials to authenticate with your AWS account.
- 3.Use the SDK to make API calls for enabling log file integrity validation for the CloudTrail trail.
Refer to the AWS SDK documentation for the specific language you are using to get detailed code examples and instructions.
