Amazon Macie

AWS data security service that uses machine learning and pattern matching to discover sensitive data such as PII in Amazon S3.

Definition

Macie inventories S3 buckets, evaluates their security and access controls, and runs discovery jobs to identify sensitive data such as names, credit card numbers and credentials. Findings integrate with Security Hub and EventBridge.

Example

Macie finds a publicly shared bucket containing files with Social Security numbers.

Exam tip

Macie is S3-focused sensitive data discovery; it does not scan databases or EC2 disks.
