=Course Abstract=
 +
This is not your traditional SCADA security course! This course
 +
teaches hands-on penetration testing techniques used to test embedded
 +
electronic field devices, network protocols, RF communications, and
 +
controlling servers of ICS and Smart Grid systems like PLCs, RTUs,
 +
smart meters, Home Area Networks (HAN), smart appliances, SCADA,
 +
substation automation, and synchrophasors. This course is structured
 +
around the formal penetration testing methodology created by the
 +
National Energy Sector Cybersecurity Organization Resource (NESCOR), a
 +
United States Department of Energy project. Using this methodology and
 +
SamuraiSTFU (Security Testing Framework for Utilities), an open source
 +
Linux distribution for pentesting energy sector systems and other
 +
critical infrastructure, we'll perform hands-on penetration testing
 +
tasks on embedded electronic field devices, their RF communications,
 +
and the myriad of user interfaces used throughout smart grid systems.
 +
We’ll tie these techniques and exercises back to the smart grid
 +
devices that can be tested using these techniques. We will also do
 +
exercises on dissecting and fuzzing smart grid protocols like modbus,
 +
DNP3, IEC 61850, ICCP, ZigBee, C37.118, and C12.22. The course
 +
exercises will be performed on a mixture of real world and simulated
 +
devices to give students the most realistic experience as possible in
 +
a portable classroom setting.
 +
 +
Advances in modern ICS systems such as the energy sector’s "Smart
 +
Grid" brings great benefits for electric utilities and customer alike,
 +
however these benefits come at a cost from a security perspective.
 +
With increased functionality and addition inter-system communication,
 +
the smart grid brings with it a greater risk of compromise that both
 +
utilities and customers must accept to realize their desired business
 +
benefits. To minimize this risk, penetration testing in conjunction
 +
with other security assessment types must be performed to minimize
 +
vulnerabilities before attackers can exploit the critical
 +
infrastructures that exist in all countries around the world.
 +
 +
