To learn more visit: http://www.unisys.com/gettozero Unisys Stealth™ can protect industrial enterprises’ critical infrastructure in a flexible, non-disruptive manner. Hacks or attacks on chemical processing controls could cause system failures, equipment damage, or environmental hazards. Stealth is innovative software-based security designed to protect the command and control center and conceal automated systems from hackers, viruses, or other cyber threats. If attackers cannot see the command center or any of its critical components, there is little attack surface to target or compromise. Proprietary processing techniques and other intellectual property can be safeguarded from theft or snooping.

Advance Safety and
Cybersecurity
DON’T BE A TARGET. GO DARK WITH UNISYS STEALTH.

2. Executive Overview2
Zero Incidents:
Your Goal. Our Mission.
To remain competitive, deliver the best products to
the market securely, and meet increased regulatory
requirements, the chemical processing industry must
modernize. Unfortunately, these goals are often at
odds with one another. Innovation and competitive-
ness rely on new technology that integrates business
processes (real-time analytics, enterprise resource
planning, supply chain automation) with production.
But the introduction of the latest supervisory control
and data acquisition (SCADA) systems, industrial
control systems (ICS), and programmable logic
controllers (PLCs) and their related human-machine
interface (HMI) and machine-to-machine (M2M)
software puts chemical companies at significant
risk for cyber-attacks.
According to a recent report in Reuters (March 2014),
at least 48 chemical and defense plants were
attacked with a virus called ‘Nitro.’ Sources report
the virus originated in China, and the targets were
vulnerable to data theft, such as formulas and pro-
cessing techniques. Such viruses can also disrupt
operations and bring down entire network systems.1

How can chemical companies protect their facilities
against advanced persistent threats (APT) and other
sophisticated cyber-attacks while also reducing
costs and improving agility? With Unisys Stealth™,
you can:
Go invisible. Make servers, devices, and other
endpoints dark and undetectable to hackers and
unauthorized users inside and outside your enterprise.
Isolate segments of your data center based
on user identity. Define and control access to
mission-critical systems and information based
on need-to-know access.
Secure data-in-motion. Protect data with
point-to-point encryption.
Consolidate. Reduce reliance on physical
IT infrastructure.
Scale and adapt. Upgrade legacy systems, easily
meet emerging needs and compliance requirements
with agile, software-based security.
Keep Critical Infrastructure Secure

3. Executive Overview3
Stop Cyber Assaults
Before They Happen
Unisys Stealth takes a radically different approach
to addressing the most critical security concerns.
Stealth is designed to make SCADA/ICS and PLC
endpoints at chemical processing plants on the
command and control network invisible to unauthor-
ized users and to secure data-in-motion across any
network. This is how Stealth can help chemical
companies Get to Zero Incidents.
By creating highly-trusted communities of interest
(COI), Stealth is designed to allow only authorized
users to access automated devices, applications,
and systems critical to the chemical processing
facility. In addition to strengthening mission-critical
protection, chemical companies can reduce
infrastructure costs by safely modernizing their
industrial controls and software with one unified
security solution. And as business requirements or
regulatory mandates change, Stealth can deliver
the agility enterprises need without requiring costly
upgrades or extensive reconfiguration.
Why Stealth Now?
Unisys Stealth is the innovative, mission-critical
security that chemical companies need to help
secure their operations:
No operational disruption. Stealth works with existing
firewall, intrusion detection, and other security
systems with easy installation so you can upgrade
your systems without compromising security.
Reduces risk. Make automated chemical processing
controls such as ICS/SCADA endpoints and HMI
systems invisible. Isolate critical systems from the
rest of the enterprise. Tighten access control based
on user identity. Make mobile and wireless
applications more secure. Protect data-in-motion
over the industrial control network.
Facilitates compliance. Stealth can help achieve
compliance with the Executive Order on Improving
Critical Infrastructure Cybersecurity, and other
regulatory requirements and recommendations.
Reduces costs. Protect the chemical processing
enterprise system, including sensitive financial,
production processes, formulas, and network data
with one cost-effective solution.
Improves agility. Stealth allows for quick, easy
changes to accommodate rapidly evolving
business needs.

When it comes to critical infrastructure, there
can be no compromise. Stealth can help move
your organization from vulnerable to mission-
critically secure. But don’t take our word for it.
