Overview

CipherTrust Cloud Key Manager (CCKM, also referred to as CCKM Embedded) centralizes the management of key life cycle for various cloud services providers. The CCKM complies with data security mandates in cloud storage environments while retaining the custodianship of the encryption keys. Enterprises can back up keys on-premise, destroy keys when no longer needed, and manage the entire life cycle of the cloud keys.

The following diagram shows the high level CCKM overview:

CCKM Functionality

The CCKM provides following functionalities for the supported cloud services:

• Life cycle management of keys, key versions, and attributes:

  • View Keys

  • Update Keys

  • Upload Keys

  • Rotate Keys

  • Delete Keys

• Disaster recovery of keys:

  • Backup Keys

  • Restore Keys

• Hybrid key management:

  • On-premise keys storage

  • Management of both keys originating from trusted key sources and cloud-provider-sourced keys

  • Key synchronization

• Compliance management:

  • On-premise key storage with up to FIPS 140-2 Level 3 certification (CipherTrust Manager K570 with K7 card)

• Key visibility reporting:

  • Key Activity Report: Inspect individual key histories by operations, for example, when they were refreshed, rotated, edited, or deleted. Also, use this report to compare key activities between CCKM and a cloud service.

  • Key Aging Report: Track keys by their expiration dates. Audit a range of dates, from past material deletions to future scheduled deletions, within a cloud service.

  • Service/Usage Report: Monitor key usage by tracking services and applications consuming the keys. View when and where a service requests the use of each key.

  Note

  Reporting is not supported for the Azure Stack cloud. All clouds do not support all types of reports. Refer to related sections of the CCKM documentation for cloud-specific reports.

User Roles

CCKM has the following users with different responsibilities in administering and using the resources of supported clouds and key sources.

CCKM Admins

There is a System Defined Group named "CCKM Admins". Users within the "CCKM Admins" group are CCKM Administrators. Additionally, the CCKM administrators need the Key Users, Connection Admins, and User Admins permissions to perform key operations on the supported clouds.

A CCKM Administrator is responsible for creating and managing the following resources:

• AWS KMS Accounts, AWS Keys, AWS Custom Key Stores

• Azure Key Vaults, Azure Subscriptions, and Azure Keys

• Google Cloud Projects, Key Rings, and Keys

• Google EKM endpoints

• Microsoft DKE endpoints

• Salesforce Organizations, Tenant Secrets

• SAP Groups, SAP Keys

• CCKM Schedules

• CCKM Reports

CCKM Users

There is a System Defined Group named "CCKM Users". CCKM users registered with the CipherTrust Manager are part of this group. Additionally, the CCKM users need the Key Users permissions to perform key operations on the supported clouds. As well, they need custom key store permissions to manage AWS custom key stores.

Additional ACLs/Permissions

Additional ACLs/permissions can be granted to different CCKM roles on individual cloud resources such as AWS Accounts, Azure Key Vaults, Google Key Rings, Oracle Vaults, Salesforce Organizations, and SAP Groups.

Refer to the CCKM documentation of the respective clouds.
