Which of the following services is focused on managing access permissions in AWS?

• A. AWS Certificate Manager (ACM)
• B. AWS Identity and Access Management (IAM)
• C. AWS WAF
• D. AWS Firewall Manager

Answer: (B)

The correct choice is AWS Identity and Access Management (IAM), as it is specifically designed for managing access permissions within AWS. IAM allows users to create and manage AWS users and groups and set permissions to allow or deny their access to AWS resources. It provides fine-grained access control, enabling organizations to implement the principle of least privilege—granting only the permissions necessary for users to perform their tasks. IAM supports various authentication methods, including multi-factor authentication (MFA), and allows you to define detailed policies that dictate which actions can be taken on specific resources. This service plays an integral role in securing AWS environments by ensuring that access to resources is tightly controlled and monitored. AWS Certificate Manager (ACM) is focused on managing SSL/TLS certificates, primarily used for securing website communications. AWS WAF (Web Application Firewall) is a security service that helps protect web applications from common web exploits. AWS Firewall Manager is used to centrally manage firewall rules across multiple AWS accounts and resources. While these services contribute to overall security, they do not specifically manage access permissions in the same way that IAM does.
