A company wants to identify Amazon S3 buckets that are shared with another AWS account. Which AWS service or feature will meet these requirements?
A
AWS Lake Formation
B
IAM credential report
C
Amazon CloudWatch
D
IAM Access Analyzer
Explanation:
IAM Access Analyzer is the correct service for identifying Amazon S3 buckets that are shared with another AWS account. Here's why:
Resource Analysis: Helps identify resources (like S3 buckets) that are shared with an external entity
Cross-Account Access Detection: Specifically designed to find resources accessible from outside your AWS account
Security Best Practices: Part of AWS security services that help maintain least-privilege access
AWS Lake Formation: Used for building, securing, and managing data lakes, not for identifying cross-account access
IAM Credential Report: Provides information about IAM users and their credentials, not resource sharing
Amazon CloudWatch: Used for monitoring and observability, not for identifying cross-account resource access
IAM Access Analyzer continuously monitors your AWS environment and alerts you when resources are shared with external entities, making it the ideal choice for this security requirement.
