# HSM (Hardware Security Module)

## What is a Hardware Security Module (HSM)?

A **Hardware Security Module (HSM)** is a hardened, tamper-resistant device that plays a
critical role in securing cryptographic processes. It generates, manages, and protects
cryptographic keys used for encrypting and decrypting data, as well as creating digital
signatures and certificates.

HSMs adhere to rigorous standards like [FIPS 140-2](https://www.corbado.com/glossary/fips-140-2) and Common
Criteria, ensuring they meet the highest security levels required by regulatory standards
such as GDPR, [eIDAS](https://www.corbado.com/glossary/eidas), and
[PCI DSS](https://www.corbado.com/blog/pci-dss-4-0-authentication-passkeys).

### Understanding HSMs

- **Security and Compliance:** HSMs help organizations meet and exceed various
  cybersecurity standards, ensuring data protection and compliance with laws like GDPR and
  HIPAA.
- **Operational Flexibility:** Offers both on-premises and cloud solutions (HSM as a
  service), providing flexibility and scalability to businesses.

### Why Use an HSM?

- Ensures that cryptographic keys are well-protected against sophisticated attacks.
- Supports a wide range of applications, from cloud computing to digital signing,
  enhancing security across multiple platforms.

### Applications and Use Cases

- **Cloud and Containers:** Secures keys and data in cloud environments and containerized
  applications.
- **Public Key Infrastructure (PKI):** Protects critical PKI root and CA signing keys,
  linking back to the **Root of Trust**.
- **Digital Identity and Authentication:** Creates and manages credentials for secure
  digital identities and transactions.
