Overview

CipherTrust Cloud Key Manager (CCKM) 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.

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

• AWS China

• AWS GovCloud

Supported Cloud Services

• AWS Customer Managed CMKs

Supported Key Sources

CCKM uses the CipherTrust Manager as the trusted key source for the encryption keys employed within the supported clouds. 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

• Oracle Cloud

• Microsoft Azure

• Google Cloud Platform

• Private Clouds - VMware vSphere and Microsoft Hyper-V

• Physical Appliances

Refer to the CipherTrust Manager Deployment Guide for details.

Supported Internet Browsers

The CCKM supports the following Internet browsers:

• Chrome 51.0.2704 (64-bit) or later

• Firefox 45.0 or later

• Internet Explorer 11 or later

  Note

  Internet Explorer is not supported for CipherTrust Manager version 2.5 or higher.

User Roles

CCKM has the following users with different responsibilities in administering and using the AWS resources.

CCKM Admins

There is a System Defined Group named "CCKM Admins". Users within the "CCKM Admins" group are CCKM Administrators.

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

• AWS Accounts

• AWS Keys

• CCKM Schedules

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 Admins permissions to perform the AWS key operations

• (Optional) The Audit Admins permissions to view the log messages

Proxy Configuration

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

Prerequisites

Make sure that:

• The root access is enabled. Contact Thales Customer Suport to enable the root access.

• DNS is already configured on the CipherTrust Manager if you want to use the hostname of the proxy server.

Steps

To configure the proxy:

1. SSH to the CipherTrust Manager appliance.

2. Go to /opt/keysecure/optional-services.

3. Open docker-compose.citrus.yml and docker-compose.cckm.yml files in an editor (for example, the vi editor).

4. Add the following two lines under the environment section in both the files.

   - https_proxy=172.14.3.4:3128/
   - NO_PROXY=localhost,127.0.0.1
   

   Note

   Make sure that indentation is proper.

   For example, the updated content should look similar to the following:

   services:
     citrus:
       image: 647496772601.dkr.ecr.us-east-1.amazonaws.com/ncryptify/citrus:latest
       depends_on:
         - fluentd
         - pg
         - doorway
       restart: unless-stopped
       environment:
         - PORT=8080
         - YUGOLOG
         - DEBUG_RESPONSES
         - ENABLE_DEBUG_METRICS
         - DATABASE_URL=postgres://postgres:postgres@/kylo?sslmode=disable&host=/var/run/postgresql&search_path=citrus,extensions
         - DATABASE_MAX_OPEN_CONNS=20
         - DATABASE_MAX_IDLE_CONNS=20
         - CLERK_URL=http://clerk:8084
         - MINERVA_URL=http://minerva:8082
         - ENIGMA_URL=http://enigma:8083
         - DBMGR_URL=http://dbmgr:9080
         - SALLYPORT_URL=http://sallyport:8081
         - RANDOM_SOURCE=PIPE
         - RANDOM_PIPE_NAME=/dev/urandom
         - TOKEN_PARTITION=ca1a7049-ca97-4473-b611-97a056c42246
         - NC_PUB_KEY=SERVICE
         - DARKSTAR_URL=http://citrus:@darkstar:8080
         - PRODUCTS=cckm,cte,data discovery
         - CLIENT_CREDENTIAL_PARTITION=edf4facc-4ccd-46dd-8aa3-b8538eef26d7
         - CLIENT_CREDENTIAL_ID_NAME=clientID
         - CLIENT_CREDENTIAL_SECRET_NAME=clientSecret
         - HOST_DAEMON_NTP_URL=/host-daemon/host-daemon.sock
         - DOORWAY_URL=http://doorway:8080
       volumes:
         - pg_sockets:/var/run/postgresql
         - ./csprng/rand:/dev/urandom
         - ./host-daemon:/host-daemon
       logging:
         driver: fluentd
         options:
           tag: ci
   

   Similarly, you can use the authenticated proxy. For example, add the following lines to the files:

   - https_proxy=pxuser:Vormetric123!@ip-172-31-16-234.ap-south-1.compute.internal:3128/
   - NO_PROXY=localhost,127.0.0.1
   

5. Go to /opt/keysecure.

6. Run ./up.sh.

7. In a different console, monitor the following:

   tail -f /opt/keysecure/logs/keysecure.system.log | grep "citrus"
   tail -f /opt/keysecure/logs/keysecure.system.log | grep "navic"
   

8. Make sure no errors related to the services are displayed. If any errors are reported, fix them.

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.

Amazon Web Services

AWS GovCloud

AWS China Cloud

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.
