Why Securing our Critical Infrastructure Matters
Operational Technology (OT) remains a key, but vulnerable, technology for organizations with critical infrastructure. The U.S. Government has defined critical infrastructure as those “systems and assets, whether physical or virtual, so vital to the United States that the incapacity or destruction of such systems and assets would have a debilitating impact on security, national economic security, national public health or safety, or any combination of those matters.”
OT systems are crucial components in producing and delivering many of the resources that we rely on daily, such as clean water, fuel, and electricity. Other Industrial Control Systems (ICS) are fundamental to necessary services such as traffic light systems, automotive plants, and waste management facilities. Despite the societal importance and reliability of these systems, OT infrastructure remains insecure and vulnerable to cyberattacks that can cause physical harm to the public or interrupt the delivery of critical services.
Organizations operating critical infrastructure can mitigate the impact of security incidents and increase the resiliency of their OT infrastructure by following some key components of basic cybersecurity hygiene.
