Operational Technology (OT) systems have been used to manage everything from factories to transportation networks to utilities for years. Most citizens, however, do not consider these mechanisms until there is a problem. That's why the attack on Colonial Pipeline in May 2021 came as such a shock. The attack on a segment of the enterprise went beyond IT, causing a brief but significant disruption in OT-based fuel supplies, prompting the Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) to issue an advisory urging critical infrastructure (CI) asset owners and operators to maintain a high level of awareness.
