Integration features

Automated XCrypt Full Disk installation and administration processes simplify deployment.

No changes to VMware Tanzu Greenplum customers’ existing back-up process, high-level applications nor code is required when deploying XCrypt Full Disk, making the solution non-disruptive.

XCrypt Full Disk automatically integrates with KMIP key managers and PKCS#11 HSMs that exist in the customer’s environment, protecting the customer’s security infrastructure investment.

XCrypt Full Disk also includes a software-based Virtual Key Manager, Client and Virtual HSM (hardware security module), which can be alternatively deployed.

VMware Tanzu Greenplum customers can use XCrypt Full Disk to encrypt data at rest (DAR) and data in motion (DIM). XCrypt for DIM encrypts and protects all traffic within the VMware Tanzu Greenplum cluster/segment nodes.

XCrypt Full Disk is tightly integrated with VMware Tanzu Greenplum to provide encrypted data access control. As a result, enterprise applications running in VMware Tanzu Greenplum, on top of XCrypt Full Disk, experience no degradation in performance.

XCrypt Full Disk is transparent to higher level file systems, databases, and applications. No customization of high-level applications or code modification is required when deploying XCrypt.

Typical VMware Tanzu Greenplum deployments use Data Domain as their backup infrastructure, which is a necessity for data recovery. De-duplication in the backup infrastructure requires data to be in the clear. With XCrypt Full Disk, no changes need to be made to the existing backup process.

VMware Tanzu GemFire customers can use XCrypt Full Disk for automatic snap-shotting of the in-memory database contents at user-configurable intervals.

“The largest advantage that I found in working with Zettaset’s DAR and DIM modules was how easy they were to deploy. Usually, adding encryption is a painful endeavor. However, Zettaset’s installation was fairly simplistic. Making maintenance a simple, disciplined process is a key part of the overall solution.”

How it works

As the VMware Tanzu Greenplum server boots up and mounts an encrypted partition, it needs to exchange information with a key management server. Once the proper handshakes have taken place, the Zettaset XCrypt Full Disk technology allows a decrypted version of the server volumes to be mounted and treated like a normal partition. Zettaset provides the pieces to automate all of this and integrate with your existing key management and HSM (hardware security module) solutions. The Zettaset XCrypt Full Disk solution also includes a virtual key manager and virtual HSM which can alternatively be deployed if needed.

Encrypting Data at Rest

Figure 1 depicts the mount points that you would typically encrypt in a VMware Tanzu Greenplum environment in order to protect data. In this scenario, you would be using the Zettaset key management server to store and manage credentials. As the servers in the cluster booted, they would do a key exchange with the Zettaset server following the LUKS specification. If this exchange works, the server would then be able to mount the /data partition us dm-crypt so that the primary could read the files it needs out of /data/primary. The segment nodes would each individually go through their own exchange and validations so that they could access the /data partition which contains the files necessary to run the primary, and mirror and present their data.

Encrypting Data in Motion

Many companies also want to protect data as it is passed between nodes. Normally, this traffic sits on its own interconnect, and it is segmented away from any other network access. This is typically enough protection for most use cases. Since we see more cloud and virtualized deployments of VMware Tanzu Greenplum, there are more requests to encrypt the traffic that passes between the nodes. Zettaset’s XCrypt Full Disk encryption for DIM (Data In Motion) installs and manages the pieces that allow you to encrypt data as it passes between nodes. The encryption is applied to communication from the primary to segment hosts, segment hosts to the primary, and between the segment hosts themselves.
