HISTORY OF CYBER INCIDENTS AND THREATS TO INDUSTRIAL CONTROL SYSTEMS

Industrial control systems (ICSs) are embedded cyber devices that operate critical infrastructures (e.g., energy, transportation, water). ICS devices are lesser known and are typically unique to the operational technology (OT) framework of cyber, which differs from enterprise information technology (IT). This paper documents some of the more significant ICS threats, vulnerabilities, and incidents to help demonstrate the increase and complexity of ICS attacks. Cyber threats in ICSs manifest themselves in different ways.

In this paper, we examine the different ICS threat types, which include directed attacks, cyber intrusion campaigns, malware, and cyber threat groups.
