Operational Technology (OT) refers to hardware and software used to monitor control and
manage industrial processes infrastructure and assets across sectors like manufacturing
energy transportation and utilities. It includes systems such as Industrial Control Systems
(ICS) SCADA PLCs and DCS. ICS Security is the protection of industrial automation and
control systems that manage critical operations like power generation water treatment and oil
and gas production. Its goal is to safeguard confidentiality integrity and availability while
mitigating risks from cyber threats disruptions and unauthorized access. With this book
our goal is to help readers understand how to secure complex industrial environments by
providing a clear introduction to ICS and OT security. We will begin by explaining what ICS
and OT are how they differ from traditional IT and why those differences matter. From there
the discussion will focus on the increasing importance of ICS OT security—particularly in the
context of IT and OT convergence where systems and data are becoming more interconnected.
You will also gain an understanding of the key components that make up Industrial Control
Systems and how they work together to monitor and control industrial operations. These
components—including SCADA PLC HMI and DCS—are essential for ensuring operational efficiency
safety and security in industries like manufacturing energy and critical infrastructure.
