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:

Supported Key Sources

CCKM uses the following as the trusted key sources for the encryption keys employed within the supported clouds:

• 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.

The CipherTrust Manager supports all clouds that CCKM supports. The CipherTrust Manager stores its own keys and the backup keys from the supported clouds.

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

• 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.

Proxy Configuration

If you plan to run the CipherTrust Manager appliance behind a proxy, you must configure the proxy, as described in Proxy Configuration.

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.

URLs to Whitelist for Running CipherTrust Manager Behind Proxy

The following URLs must be whitelisted before you run the CipherTrust Manager behind a proxy.

Connecting CCKM in Amazon Virtual Private Cloud (VPC)

When AWS KMS is in Amazon VPC, CCKM cannot connect with the EC2, KMS, and STS services using public IP addresses. 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, 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

1. Create the VPC endpoint for a service.

2. Copy the DNS name of the service.

3. Ping the DNS name to find out the associated IP address.

4. Copy the IP address.

On CipherTrust Manager

1. Log on to the CipherTrust Manager GUI.

2. In the left pane, click Admin Settings > DNS Hosts.

3. Click Add DNS Host.

4. In the Hostname field, enter the service URL, for example, sts.amazonaws.com.

5. In the IP Address field, paste the copied IP address.

6. Click Save.

Similarly, add the DNS host entries for all three services, for all your AWS regions.
