ICS/OT Cybersecurity: Securing OT (Operational Technologies) and ICS (Industrial Control Systems) Networks Against Both Internal and External Threats, Intentional or Accidental

Manufacturers are continually looking for ways to improve their production efficiency, reduce cost and waste, and monitor quality to confirm standards are met. As a result, the world’s manufacturing facilities embrace the adoption and deployment of technologies that connect more and more assets and devices to their networks.  The benefits of collecting data for timely and clear reporting, or leveraging analytics to uncover process trends and predict manufacturing yields and equipment failure, can be huge.  A connected enterprise also presents risks to the manufacturing facility, its employees, and potentially the public if the network and its OT assets are not secure.  In fact, many experts in this field believe that it’s not a matter of “if” a cybersecurity incident occurs, but “when.”

The technology now deployed in OT environments and the risks they are exposed to have many similarities to that seen in IT / enterprise environments.  However, understanding the many significant differences between OT and IT environments (e.g., priorities) and the unique and evolving security threats to OT must be considered when designing, implementing, and maintaining a cybersecurity program for an ICS/OT environment and the Critical Infrastructure sectors.

To support our clients’ cybersecurity needs, LSI’s team of experts starts by listening, learning, and understanding our clients’ processes and business drivers. By combining that understanding with our knowledge and experience of ICS/OT cybersecurity frameworks, industry regulations, and acceptable practices to assess the environment’s cybersecurity posture, we can implement the needed remediation.  The result is a custom solution, tailored to the needs of that client’s process and environment, that reduces the attack surface and hardens the environment against cyber threats.
