Which AWS service assists in managing access across AWS resources through identity verification?

AWS Identity and Access Management (IAM) plays a crucial role in managing access to AWS resources by allowing you to create and manage users, groups, and permissions. With IAM, you can define who has access to what, ensuring that only authorized users can interact with specific resources within your AWS account. This includes the ability to set fine-grained access controls that are essential for maintaining security and compliance.

IAM provides several features that aid in identity verification, such as Multi-Factor Authentication (MFA), which adds an extra layer of security by requiring additional verification details beyond just a password. Moreover, the service allows the implementation of policies that grant or deny permissions based on specific conditions, which is critical in adapting to the changing security landscape.

In contrast, other options do not focus specifically on managing access through identity verification. AWS Security Hub consolidates security findings from various AWS services but does not directly handle user identity or access management. AWS Secrets Manager is designed for securely managing and accessing secrets such as API keys and database credentials but does not manage user access to AWS resources. AWS Key Management Service (KMS) deals with creating, managing, and using encryption keys but is not involved in user access management or identity verification either. Thus, IAM stands out as the
