There is no longer a downward trend in the percentage of ICS computers on which malicious objects were blocked.
Starting with the second half (H2) of 2019, we observed a decline in the percentages of ICS computers on which malicious objects were blocked. This was observed in industrial control systems (ICS) as well as in corporate and personal computing environments. This downward trend was not observed in the second half of 2020.
Globally, the percentage of attacked ICS computers in the second half of the year was 33.4%, which was 0.85 percentage points (p.p.) higher than the first half (H1) of the year.
