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 Components
The CCKM solution comprises the following components:
CCKM GUI on the CipherTrust Manager for administrators and users
At least one of the supported clouds
A supported trusted key source
A supported Internet browser
The product is delivered as a licensed component of the CipherTrust Manager appliance that can be installed on any one of the supported deployment methods.
Supported Clouds
Amazon Web Services (AWS)
AWS China
AWS GovCloud
Azure Cloud
Azure China Cloud
Azure US Government
Google Cloud
Oracle Cloud

- Salesforce Sandbox
SAP Data Custodian
Note
AWS China cloud does not support uploading 256-bit keys. It supports 128-bit keys only. CCKM automatically uploads 128-bit keys to the AWS China cloud through the GUI. Other AWS clouds support upload of 256-bit keys.
AWS China cloud does not support creation of native asymmetric keys.
Azure China cloud has not been tested from CipherTrust Manager 2.9.0 release onward.

Supported Key Sources
CCKM uses the following as the trusted key sources for the encryption keys employed within the supported clouds:
CipherTrust Manager
External CipherTrust Manager
Azure Dedicated HSM
Luna Network HSM (referred to as Luna HSM in this document): This release supports:
Luna Network HSM Software and Firmware versions v7.3.x and higher.
PED and Password-based HSM configurations.
Import of RSA-4096 keys from Luna HSM Software and Firmware versions 7.4.x and higher.
Symmetric and asymmetric keys with Luna HSM.
Note
CCKM doesn't support FM-enabled Luna HSM as a key source.
Data Security Manager (DSM): This release supports DSM v6.4 Cumulative Patch 3 and higher.
The CipherTrust Manager supports all clouds that CCKM supports. The CipherTrust Manager stores its own keys and the backup keys from the supported clouds.
Note
On the CipherTrust Manager, CCKM cannot manage source keys created on the CCKM Appliance v1.x.
Supported Deployment Methods
The CCKM is delivered as part of the CipherTrust Manager appliance. So, CCKM can be automatically deployed with the deployment of the CipherTrust Manager in the following supported environments:
Amazon Web Services
Google Cloud Platform
Microsoft Azure
Oracle Cloud
Private Clouds - Oracle VMware vSphere, Microsoft Hyper-V, and OpenStack
Physical Appliances
Refer to the CipherTrust Manager Deployment Guide for the complete list of supported environments and deployment instructions.
Supported Internet Browsers
The CCKM supports the following Internet browsers:
Chrome 51.0.2704 (64-bit) or later
Firefox 45.0 or later
Microsoft Edge 91.0.864.37 or later
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, Luna Network HSM, DSM)
Key storage in public or private clouds, inaccessible to cloud services with FIPS 140-2 Level 1 (Luna Network HSM, DSM)
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
Luna HSM Partitions, Luna Keys
DSM Domains, DSM Keys
Google Cloud Projects, Key Rings, and Keys
Google EKM 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, DSM Domains, Google Key Rings, Luna HSM Partitions, Oracle Vaults, Salesforce Organizations, and SAP Groups.
Refer to the CCKM documentation of the respective clouds.
Proxy Configuration
If you plan to run the CipherTrust Manager appliance behind a proxy, you must configure the proxy, as described in Proxy Configuration.
Note
For CCKM, configure an HTTPS proxy.
For the list of URLs to be whitelisted, refer to URLs to Whitelist for Running CipherTrust Manager Behind Proxy.
Now, you should be able to connect CCKM with the cloud through the proxy.

Connecting CCKM in Amazon Virtual Private Cloud (VPC)
When AWS KMS is in Amazon VPC:
IAM is not supported, as it is a global AWS service. Therefore, CCKM users cannot fetch IAM roles and users.
CCKM cannot connect with the EC2, KMS, Logs, and STS services using public IP addresses. If their endpoints are not added on AWS, you cannot add AWS connections and AWS keys on the CipherTrust Manager. For successful connection, add the IP addresses of VPC endpoints for these services for your AWS regions to the DNS hosts on the CipherTrust Manager.
For example, you need to add the IP addresses of VPC endpoints of sts.amazonaws.com, ec2.us-east-1.amazonaws.com, logs.us-east-1.amazonaws.com, and kms.us-east-1.amazonaws.com service URLs to the DNS hosts list.
To add the IP address of a VPC endpoint:
On AWS Console
Create the VPC endpoint for a service.
Copy the DNS name of the service.
Ping the DNS name to find out the associated IP address.
Copy the IP address.
On CipherTrust Manager
Log on to the CipherTrust Manager GUI.
In the left pane, click Admin Settings > DNS Hosts.
Click Add DNS Host.
In the Hostname field, enter the service URL, for example,
sts.amazonaws.com.In the IP Address field, paste the copied IP address.
Click Save.
Similarly, add the DNS host entries for all three services, for all your AWS regions.
