OT security remains a challenge for the leaders



Organizations represented by the OT leaders who participated in a survey have been largely unsuccessful at preventing cyber criminals from intruding their systems. Nine out of 10 organizations experienced at least one intrusion in the past year, which is almost identical to the results of last year’s survey. Even though the pandemic was an unusual situation, a 90% rate of intrusion represents a significant problem that should concern OT leaders. There was a significant change in insider breach instances, which have increased to 42%. Unlike unintentional security accidents, such as an employee who clicks a bad link, bad actors have malicious intent, which means OT leaders should carefully consider who has access to their systems. Additionally, with many employees working from home, it is likely that the security issues related to home networks contributed to problems.



The fact is OT leaders were not prepared for changes related to the pandemic and had to quickly increase budgets and change processes. The two most important things are SOCs and NOCs which needs more staff and equipment because the pandemic accelerated digital transformation and increased the need for connectivity for secure remote access. The pandemic accelerated the need for third-party secure remote access because technical staff could not be on-site doing work in person. The survey showed significant growth in phishing attacks with 58% reporting this type of intrusion, up from 43% last year. The increase in phishing stems from attackers exploiting weaknesses related to the rapid changes to working that occurred at the beginning of 2020. No one was immune, and along with everyone else, OT organizations were affected. Increased digital connectivity of OT and IT networks rolls on.
