Security in Amazon Web Services (CISN 74A) 2025 – 400 Free Practice Questions to Pass the Exam

The main service used to manage user identities and permissions in AWS is AWS Identity and Access Management (IAM). IAM allows organizations to create and manage AWS users and groups and set permissions to allow or deny access to AWS resources. This capability is essential for maintaining security and adhering to the principle of least privilege, which recommends granting users the minimum levels of access required to perform their job functions.

With IAM, administrators can define fine-grained access policies that control what IAM users and roles can do with various AWS services and resources. This includes assigning permissions based on roles, which simplifies the management of credentials and enhances security by allowing permissions to be tied to job functions rather than individual users.

In contrast, the other services mentioned serve different purposes. The AWS Personal Health Dashboard provides a personalized view into the performance and availability of AWS services underlying your AWS resources, which isn't focused on identity or permissions management. AWS Resource Access Manager helps users share resources across accounts but does not handle user identity management. AWS Config is utilized to assess, audit, and evaluate the configurations of AWS resources, primarily for compliance purposes, rather than managing user identities and permissions.
