A company is storing sensitive data in an Amazon S3 bucket. The company must log all activities for objects in the S3 bucket and must keep the logs for 5 years. The company's security team also must r

Configuring AWS CloudTrail to log S3 data events captures all object-level API actions, including deletion attempts, which is crucial for comprehensive activity logging and security auditing.

S3 server access logging records requests to the bucket, but CloudTrail data events provide a more granular and API-centric view of object activities, which is better for auditing specific actions like deletions and integrates with CloudTrail's centralized logging.

While S3 can send events directly to SNS, using EventBridge (as in option D) provides more advanced filtering and routing capabilities, making it a more flexible and robust solution for specific event types like object deletions before sending notifications.

Configuring Amazon S3 to send object deletion events to an Amazon EventBridge event bus, which then routes to an SNS topic, provides a robust and flexible mechanism to filter specifically for deletion attempts and send immediate email notifications to the security team.

Amazon Timestream is a time-series database and is not the primary or most cost-effective service for storing general S3 access logs or CloudTrail logs for long-term retention and compliance; an S3 bucket with lifecycle policies is more appropriate.

Configuring a new S3 bucket to store the logs, combined with an S3 Lifecycle policy, ensures cost-effective storage for the required 5-year retention period by transitioning data to cheaper storage classes like S3 Glacier after an initial period.
