AWS Certified Cloud Practitioner (CLF-C02) · Test 2 · question 4 of 10

Security & Complianceeasy

A compliance officer needs to find out which of the company's hundreds of Amazon S3 buckets contain personally identifiable information, such as passport numbers and credit card numbers, and to be alerted if a bucket becomes publicly accessible. Which AWS service is designed for this?

Select one answer
Show answer and explanation

Answer:

  • C. Amazon Macie

Amazon Macie is a data security service that discovers sensitive data in Amazon S3 by using machine learning and pattern matching. Its managed data identifiers detect many types of PII, financial information, and credentials, and it maintains an inventory of your S3 buckets and generates findings for issues such as a bucket becoming publicly accessible.

Option A, GuardDuty, is a threat detection service that analyzes logs such as CloudTrail events to identify unexpected or malicious activity; it does not inspect object contents for PII. Option B, Amazon Inspector, scans EC2 instances, container images, and Lambda functions for software vulnerabilities and unintended network exposure. Option D, Amazon Detective, helps investigate the root cause of security findings by analyzing and visualizing related activity; it does not classify data stored in S3.
