Here is a summary of the content:
The conversation revolves around the importance of effective communication between IT and OT (Operational Technology) professionals in the context of industrial control systems (ICS) security. The speakers emphasize that building credibility and trust is crucial before asking for changes or implementing new security measures.
To achieve this, it’s essential to understand the pain points and challenges faced by OT personnel and to involve them in the decision-making process. By doing so, they will be more likely to follow guidance and implement security measures.
The conversation also touches on the importance of setting realistic goals and milestones for security implementation, using frameworks such as the Cyber Security Framework or IEC 62443. This approach allows for a measurable and incremental improvement in security over time.
Additionally, the speakers highlight the need for IT professionals to be aware of OT processes and terminology to facilitate better communication. They suggest that IT personnel should learn about OT operations and use relatable language to explain security concepts, making it easier for OT engineers to understand and implement security measures.
Overall, the discussion emphasizes the importance of collaboration, effective communication, and a gradual approach to implementing ICS security measures.
