Question #1152

A company needs to categorize its users into logical units to efficiently apply access policies across multiple accounts. Which AWS service or feature should be used to achieve this?

A

Security groups

B

AWS Identity and Access Management (IAM)

C

Resource groups

D

AWS Security Hub

Explanation

The correct answer is B (AWS IAM) because:
- IAM Groups allow organizing users into logical units and attaching policies to grant permissions collectively, ensuring efficient policy management.
- Security Groups (A) control network traffic for resources like EC2 instances, not user access policies.
- Resource Groups (C) organize AWS resources (e.g., EC2, S3), not users or access policies.
- AWS Security Hub (D) aggregates security findings but does not manage user access.

Key Points:
- IAM Groups simplify policy application by grouping users with similar access needs.
- Cross-account access can be achieved via IAM roles or AWS Organizations, but user grouping is inherently an IAM feature.
- Security Groups and Resource Groups are resource-centric, not user-centric.

Answer

The correct answer is: B
