Smart Grid, autOmatiOn, and
Scada SyStem Security
YONGGE WANG
In this chapter, we discuss the challenges for secure smart
energy grid and automation systems. We first describe the
current security status and existing attacks on power grid and
critical infrastructures. en, we use the supervisory con-
trol and data acquisition (SCADA) system as an example to
show the challenges in securing the automation and smart
power grid systems. Distributed control systems (DCSs) and
SCADA systems were developed to reduce labor costs and
to allow systemwide monitoring and remote control from
a central location. Control systems are widely used in such
critical infrastructures as the smart electric grid, natural gas,
water, and wastewater industries. W
