3. Zettaset: Born in Big Data
Zettaset™ Big Data encryption
solutions protect and assure the
integrity of critical data, on-
premises and in the cloud
3 © 2016 Zettaset, Inc. | Proprietary and Confidential
 Specifically designed for
optimized scalability and
performance in today’s
distributed computing systems
and Big Data environments
 Ideally suited for elastic cloud
deployments, massive volumes
of structured / unstructured
content
 Software-based approach to
encryption key management
and hardware security modules
sets new bar for ease of
administration combined with
significant TCO advantages

4. Data-centric security solutions for Big Data and Cloud environments
must not suffer the same drawbacks that make legacy solutions
irrelevant, namely:

What Problems with Existing Technology Does
Zettaset Address?
• Inability to adapt to elastic environments
• Inability to adapt to distributed
architectures
• Lack of automation
• Scalability issues
• Performance issues
• Inability to adapt to multiple databases,
file systems
• Intrusive implementations

5. • In today’s competitive economy,
data is the primary asset
enterprises and individuals possess
• In cloud computing, foremost
concern is about data integrity,
confidentiality and privacy
• The only way to secure databases
on virtual machines or in cloud
environments, without sacrificing
the huge benefits of these new
architectures, is to use software-
based solutions that share the
elasticity of virtual machines and
cloud computing

6. Zettaset Encryption Suite:
Optimized for Protection, Performance and Scalability
in Big Data Distributed Systems and the Elastic Cloud
© 2016 Zettaset, Inc. | Proprietary and Confidential6
High performance volume-
level encryption for
Hadoop, NoSQL, and
Relational data stores
Granular, authenticated
file-level encryption for
HDFS and S3, plus added
data integrity protection

7. Application
Direct integration with encrypt and decrypt API
Database (RDBMS)
Transparent to applications with integration to crypto API
File System
Files and directories that are part of database
Disk
Partition-level or entire disk
Self-Encrypting Drive (SED)
Transparent to all layers above

Data-at-Rest Encryption Layers

Key
Manager

8. • Basic roles of key manager and hardware
security module (HSM) no longer sufficient
– Provide secure storage
– Protect and retrieve keys
Scale and volume of Big Data and
complexity of cloud requires more
comprehensive approach to key
management and administration
• Automation of features, like node removal and
key revocation
• Policy creation and enforcement
• Key rotation without re-encryption
• Per-user granularity

Key Management for Big Data:
Old Rules Don’t Apply
© 2016 Zettaset, Inc. | Proprietary and Confidential
"Key management is
the hardest part of
cryptography and often
the Achilles' heel of an
otherwise secure
system.”
- Bruce Schneier
Cryptographer and Security Expert,
Berkman Center for Internet &
Society at Harvard Law School

Performance and Scalability in
Any Big Data Environment:
NoSQL, Relational, and Hadoop

V-Key Mgr V-HSM
• Data-at-Rest
• Data-in-Motion
• Certificate Authority
• Advanced, automated key management
• Certificates generated automatically during install
• Admin can revoke all certificates on a node to securely remove that node
Data-at-Rest
 Measured 3% performance impact
 Encrypts all existing data regardless of media
 Encrypts data on any disks – avoids premium
SED costs and offers integrated key
management
 Standalone, turnkey solution or can integrate
and leverage existing infrastructure
 Transparent to the file system
 AES 256-bit standard for optimum security
Data-in-Motion
 Measured 7% performance impact
 Secures all connections between cluster
nodes, and between cluster and management
console
 Eliminates possibility of unauthorized access
by anyone within corporate network or server
cluster
 Ensures networking connections are secure
within encrypted and authenticated tunnel

20. • To remove one or more nodes, their certificates must be
revoked, so KMIP server would no longer issue keys to
those nodes
• Get list of currently enabled hosts
– $ /usr/share/zts/bin/zts.ca list-hosts
• Revoke node certificates
– $ /usr/share/zts/bin/zts.ca revoke-host node15
• Data at Rest: node will stop functioning on next reboot
• Data in Motion: active connections will be dropped
