Insider Threats in Operational Technology How to Mitigate the Risks

In the realm of cybersecurity, external attacks often dominate headlines, but a more insidious danger lurks within: insider threats. Insider threats are particularly concerning in Operational Technology (OT) environments, which manage critical infrastructure such as power plants, transportation systems, water treatment facilities, and manufacturing lines. These environments are vital for maintaining societal functions, yet they are often vulnerable to internal risks.

While insider threats may not receive as much media attention as ransomware or nation-state attacks, they represent a serious challenge. Employees, contractors, or vendors with access to sensitive systems have the potential to cause unintentional or deliberate harm. The complexity of OT systems, coupled with the trust placed in employees, makes mitigating insider threats a difficult but crucial task.

This article explores the nature of insider threats in OT environments and outlines strategies for mitigating these risks.

Insider threats come in two main forms: malicious insiders and negligent insiders. Both pose significant risks in OT environments.
