What does AWS CloudHSM provide?

AWS CloudHSM provides a cryptographic service that allows users to maintain hardware security modules (HSMs) in the cloud. This service is focused on helping organizations securely manage cryptographic keys and perform cryptographic operations in a secure environment. By offering dedicated HSMs, AWS CloudHSM ensures that sensitive cryptographic material is protected with robust security measures and gives users full control over their keys while integrating seamlessly with their AWS applications.

The key features of AWS CloudHSM include high availability and scalability, along with compliance capabilities, making it suitable for industries that require stringent security standards. Organizations can use CloudHSM to support various cryptographic algorithms and reinforce data protection for applications and services.

The other options encompass different functionalities that are not the primary focus of AWS CloudHSM, such as user authentication, resource monitoring, and IAM (Identity and Access Management) role management, which do not pertain to the specific features and capabilities of CloudHSM. This clarity on the primary purpose of AWS CloudHSM solidifies option B as the appropriate choice.
