AWS Identity and Access Management (IAM) is the service designed for managing permissions and access to AWS resources. It allows you to create and manage AWS users, groups, and roles, as well as define permissions to specify who can access what resources and under which conditions. Through IAM, you can implement fine-grained access control over your AWS infrastructure, enabling you to enforce security best practices by ensuring that users have only the permissions they need to perform their tasks.

For instance, IAM policies can be attached to users or roles to grant specific permissions, such as the ability to launch EC2 instances or access specific S3 buckets. Additionally, IAM supports multi-factor authentication (MFA), which adds an extra layer of security for user accounts, making it a critical component in securing your AWS environment.

Other services mentioned do not primarily focus on access management. AWS CloudTrail provides logging of API calls and helps you track changes and monitor activities in your AWS account, while Amazon Inspector is a security assessment service designed to analyze applications for vulnerabilities. Amazon S3, on the other hand, is a storage service that allows you to store and retrieve data, and while it supports IAM roles for controlling access to its resources, it does not serve as a dedicated access management service itself
