A survey conducted recently by cybersecurity firm Fortinet showed that more than 90% of organizations that use operational technology (OT) systems have experienced some sort of cyber incident in the past year.
Fortinet’s 2021 State of Operational Technology and Cybersecurity Report is based on responses received in late February and early March from 100 people working for organizations with more than 2,500 employees in the manufacturing, energy and utilities, healthcare, and transportation sectors.
Fortinet told SecurityWeek that the study focused on OT systems and all respondents were responsible for some aspect of manufacturing or plant operations, but admitted that some of the reported incidents may have actually involved the organization’s IT systems.
The survey found that more than 90% of organizations experienced at least one cyber incident, and 12% reported more than 10 incidents in the past year. More than half of respondents said the incident resulted in an operational outage that affected productivity, and 45% said it resulted in an operational outage that put physical safety at risk.
The types of incidents reported by respondents included phishing (58%), malware (57%), insider breaches involving bad actors (42%), exploitation of vulnerabilities (40%), mobile security breaches (40%), removable storage devices (33%), ransomware (32%), unintentional insider breaches (31%), and DDoS attacks (24%). Phishing and malicious insider breaches recorded the most significant increase compared to previous years.

Only 4% of respondents said they were prepared for remote work before the pandemic.
