Which AWS service provides a solution for validating CloudTrail log integrity?

1. AWS Config

2. Amazon CloudWatch

3. Validate Logs functionality

4. AWS Inspector

The correct answer is: Validate Logs functionality

CloudTrail log integrity validation is a crucial part of ensuring that the logs collected by AWS CloudTrail are tamper-proof and have not been altered after they were generated. The Validate Logs functionality specifically exists within AWS CloudTrail to provide checksums for log files, allowing users to confirm that the logs have not been modified. Each log file created by CloudTrail is accompanied by a hash that can be used to verify the file's integrity against any potential changes. By utilizing the Validate Logs feature, users can ensure compliance and security standards are maintained, helping to detect malicious activity or accidental changes. This capability is essential for organizations that need to adhere to security and auditing regulations. Other options, while important in their own right, do not serve the specific purpose of validating log integrity. AWS Config, for example, helps track AWS resource configurations and compliance with governance rules, but it doesn’t deal directly with the integrity of CloudTrail logs. Amazon CloudWatch focuses on monitoring operational performance and resource health and does not provide features for log integrity verification. AWS Inspector is a security assessment service that analyzes applications for vulnerabilities and compliance, but it does not handle CloudTrail log validation.
