Indegy Awarded Patent for Invention that Actively Detects Security Threats in Industrial Control Networks

Technology Notifies Security Personnel of Unintended Changes or
Hostile Attack on Controller Firmware, Logic and/or Parameters

NEW YORK–(BUSINESS WIRE)–lt;a href=”” target=”_blank”gt;#ICSlt;/agt;–Indegy, a leader in industrial
cyber security, today announced it has received patent #10,261,489 from
the United States Patent & Trademark Office for software technology that
detects misconfigurations and hostile attacks in industrial control
networks using active querying. The patented
is part of the Indegy Industrial Cybersecurity Suite,
which is the first product to provide active and passive detection of
threats in industrial control system (ICS) based environments.

Industrial Control Systems use Programmable Controllers (PLC and DCS) to
manage processes. Any changes to the firmware, application logic or
configuration parameters of a controller, whether caused by human error
or intentionally by a hostile attacker, can result in potentially life
threatening physical and environmental damage. A recent investigative
published by the Wall Street Journal revealed that Russian
agents have already hacked into the US electric grid.

“This patent recognizes Indegy for inventing the active detection of
cyber threats to industrial control systems which accomplishes more than
passive network monitoring alone and provides visibility customers
cannot do without,” said Mille Gandelsman, CTO of Indegy. “Our unique
combination of both active and passive threat detection provides
complete visibility into all operational network activity, including
changes made directly on control devices that elude competitive

Highlights of the Indegy Patent

The patented invention works in the following way:

  • The Indegy product requests that a controller, which controls one or
    more field devices in an industrial control network, report the code
    it is currently using.
  • Indegy compares the code reported by the controller with a stored
    baseline version of the code.
  • When a discrepancy between the code reported by the controller and the
    baseline version is detected, Indegy automatically issues a
  • Indegy also reduces the number of devices needed to achieve 100%
    visibility since it eliminates the need to tap into every network
  • Finally, Indegy works in environments that don’t even have managed

The Indegy Industrial Cybersecurity Suite is purpose-built to provide
real-time situational awareness and visibility into ICS networks. It
combines behavioral anomaly detection with policy based rules for
comprehensive threat detection and mitigation, and unique visibility
into asset inventory. Industrial facilities including critical
infrastructure such as utilities, water, energy, pharmaceutical and
manufacturing use Indegy to automate operational oversight processes,
identify human errors such as misconfigurations and failed maintenance,
and protect against malware, cyber attacks and insider threats.
