To meet the requirements of rotating the master key every 45 days, achieving FIPS 140-2 Level 3 validation, and ensuring the master key is stored redundantly in multiple US regions, you should use Customer-managed encryption keys with Cloud HSM. Here's how:
* Set Up Cloud HSM:
* Deploy Cloud HSM in your Google Cloud environment. Cloud HSM provides a hardware-based key management solution that meets FIPS 140-2 Level 3 compliance.
* Create and Manage Keys:
* Create your encryption keys in Cloud HSM. These keys can be managed and rotated per your policy requirements.
* Key Rotation:
* Set up a key rotation schedule to rotate the master key every 45 days. Cloud HSM allows you to automate this process.
* Geographic Redundancy:
* Ensure that your Cloud HSM configuration spans multiple regions within the US to achieve redundancy. This will ensure that your keys are available even if a particular region experiences an outage.
* Compliance:
* Cloud HSM's FIPS 140-2 Level 3 validation ensures that your encryption keys are managed in a secure and compliant manner.
Benefits:
* Security and Compliance: Meets stringent compliance requirements.
* Automated Management: Simplifies key management and rotation.
* Redundancy: Ensures high availability of keys across multiple regions.
