Secure Critical Infrastructure
 SEL cybersecurity solutions are an
essential element to protecting systems
that operate our nation’s critical
infrastructure. Utility executives and
technicians alike are finding that these
solutions provide an effective means
for reducing electronic vulnerabilities
in their critical communications
systems. National and international
research firms have identified threats
and documented specific cases of real
cyberattacks. In some cases, it cost
hundreds of thousands of dollars to
repair the damage. SEL cybersecurity
solutions start at just under $500.
SCADA Systems Security
 SEL security devices ensure supervisory control and data acquisition
(SCADA) systems will not fall victim to disgruntled insiders, network
hackers, or even cyberterrorism.
SEL security solutions are
compatible with existing SCADA
communications protocols and
have little impact on data flow.
Proven Compatibility
With SCADA Systems
Cybersecurity devices must be
compatible with existing SCADA
communications devices and
protocols, such as data radios
and modems using DNP3 or
Modbus® protocols. Also, SCADA
cybersecurity devices must not
interfere with data flow on control and/or monitoring systems.

Authentication, Encryption, and Logging
SEL devices secure SCADA systems by authenticating and logging users as
well as encrypting and authenticating data on a wide variety of industrial
and commercial applications. SEL rigorously tests the operation of its
security devices with various SCADA devices and protocols, resulting in
designs that have little or no impact on data throughput. SEL wireless and
serial encrypting transceivers allow users to comply with NERC CIP standards.
Cybersecurity Training
 SEL provides real-world, hands-on cybersecurity training to help
customers comply with NERC cybersecurity requirements, teaching
them to implement strong electronic access controls in SEL relays and
communications products.
Participants learn how to
identify and mitigate possible
attacks and to assess real
threats and risks to power
system security.
