How can this task be accomplished?
Configure Amazon CloudWatch Events to trigger Amazon Inspector to scan the S3 buckets daily for PII. Configure Amazon Inspector to publish Amazon SNS notifications to the Compliance team if PII is detected.
Configure Amazon Macie to classify data in the S3 buckets and check the dashboard for PII findings. Configure Amazon CloudWatch Events to capture Macie alerts and target an Amazon SNS topic to be notified if PII is detected.
Check the AWS Trusted Advisor data loss prevention page in the AWS Management Console. Download the Amazon S3 data confidentiality report and send it to the Compliance team. Configure Amazon CloudWatch Events to capture Trusted Advisor alerts and target an Amazon SNS topic to be notified if PII is detected.
Enable Amazon GuardDuty in multiple Regions to scan the S3 buckets. Configure Amazon CloudWatch Events to capture GuardDuty alerts and target an Amazon SNS topic to be notified if PII is detected.
Explanations:
Amazon Inspector is designed for assessing the security of AWS resources but does not specialize in scanning S3 buckets for PII. It also does not provide specific features for identifying sensitive data like PII within S3. Therefore, this option does not effectively fulfill the task.
Amazon Macie is a security service that uses machine learning to automatically discover, classify, and protect sensitive data in AWS. It is specifically designed to detect PII within S3 buckets and provides a dashboard for findings. This option also includes using CloudWatch Events to alert the Compliance team via SNS, making it a comprehensive solution for the task.
AWS Trusted Advisor provides best practice recommendations and checks, but it does not specifically scan for PII in S3 buckets. The data loss prevention features are limited compared to what Amazon Macie offers for sensitive data detection. Thus, this option is not suitable for identifying PII.
Amazon GuardDuty is a threat detection service that continuously monitors for malicious activity and unauthorized behavior, but it is not designed to scan S3 buckets for specific types of sensitive data like PII. While it can alert on potential security issues, it does not fulfill the requirement of identifying PII in S3 buckets.
I would say the answer is:
Configure Amazon Macie to classify data in the S3 buckets and check the dashboard for PII findings. Configure Amazon CloudWatch Events to capture Macie alerts and target an Amazon SNS topic to be notified if PII is detected.
