VI. AWS CloudHSM FAQs
A. What is the difference between AWS KMS and AWS CloudHSM?
B. When should I use AWS CloudHSM instead of AWS KMS?
AWS CloudHSM is recommended when you need to control and manage your own encryption keys in single-tenant hardware, or when you have compliance requirements that cannot be met by AWS KMS.
C. What level of compliance is CloudHSM?
AWS CloudHSM is compliant with FIPS 140-2 Level 3, one of the highest levels of compliance for data security. This signifies that it meets stringent requirements for physical tamper-resistance, role-based access control, and ability to zeroize all plaintext cryptographic keys and critical security parameters within the module. This level of certification provides assurance that CloudHSM is designed to prevent unauthorized physical and logical access to cryptographic keys, making it suitable for handling sensitive data.
AWS CloudHSM offers a robust platform that enables organizations to generate, store, and manage encryption keys securely in the cloud. The service’s flexibility comes from its support for various APIs and its scalability from the ability to increase capacity on-demand. With its high compliance standards, including FIPS 140-2 Level 3, it ensures stringent security for cryptographic operations. As such, businesses seeking a solution for securely managing cryptographic keys, while maintaining control and meeting compliance requirements, will find AWS CloudHSM to be a highly suitable service.
