Cybersecurity is the protection of networks and computer systems, including hardware and software, against cyberattacks. Of particular interest to engineers is the computer control of physical systems that monitor and control transportation, pipelines, water treatment, waste treatment, chemical manufacture, factories, energy production, and other industrial processes. Two areas of cybersecurity focus are:

Information Technology (IT): computer systems including software, data, and networks
Operational Technology (OT): devices that control the physical world

OT Cybersecurity is concerned with keeping intruders out of the local control system network and detecting malicious intent from those who have access. Malicious intent may be subtle such as signal manipulation to decrease production, damage equipment, or steal information. One of the first notable cyberattacks was the Stuxnet virus that replayed normal data to the operator to run undetected while damaging equipment over a period of months.
