A company is running its application on AWS.

Amazon Macie is the AWS service designed specifically to discover, classify, and inventory sensitive data stored in Amazon S3. According to the AWS Certified Security – Specialty Study Guide, Macie can be enabled organization-wide using AWS Organizations, with a delegated administrator account that centrally manages findings across all member accounts.

By designating the security account as the delegated administrator for both Amazon Macie and AWS Security Hub, the company can centralize sensitive data findings in a single location. Macie automatically scans S3 buckets for sensitive data such as personally identifiable information (PII) and publishes findings to Security Hub for centralized visibility and reporting.

Option B and C are incorrect because Amazon Inspector does not scan S3 objects for sensitive data. Option D is invalid because AWS Trusted Advisor does not ingest Macie sensitive data findings.

AWS best practices recommend Amazon Macie with delegated administration and Security Hub integration for centralized sensitive data inventory across multi-account environments.
