A healthcare company has acquired another organization and inherited its AWS environment. Ahead of an audit, the company must discover personal health information (PHI) in Amazon S3 buckets and identify any publicly accessible S3 buckets. The company also needs to collect evidence with minimal operational effort. Which combination of actions meets these requirements? (Choose three.)

Enabling Amazon Macie and running an on-demand sensitive data discovery job using the PERSONALINFORMATION managed data identifier directly addresses the requirement to discover PHI in S3 buckets. Macie is designed for sensitive data discovery and classification. Enabling AWS Audit Manager and creating an assessment using a supported framework helps collect evidence with minimal operational effort, as Audit Manager automates evidence collection for compliance. Enabling AWS Security Hub with the AWS Foundational Security Best Practices standard and reviewing the controls dashboard for failed S3 Block Public Access controls identifies publicly accessible S3 buckets. Security Hub aggregates findings and provides a centralized view of security posture against best practices. AWS Glue with Detect PII is for data transformation and masking, not primarily for discovery and evidence collection for an audit. Amazon GuardDuty S3 Protection focuses on suspicious access patterns, not sensitive data discovery or public access identification. AWS Config with s3-bucket-public-write-prohibited checks for public write access, but Security Hub with the Foundational Security Best Practices provides a broader and more integrated view of public access controls, including read access.
