Kaspersky reported recently that it only saw a small increase in the percentage of industrial control system (ICS) computers targeted in 2021, compared to the previous year.

However, of the more than 300 respondents who took part in the latest survey, half reported seeing an increase in security incidents affecting ICS or other operational technology (OT) systems since the end of 2019.

In the past year, nearly one-third of the organizations that took part in the survey experienced a high number of incidents (at least 20). These incidents are often related to staff violating IT security policies, devices getting infected with malware, or employees inappropriately using IT resources.
