I'm interested in understanding the practical implications of OT (Operational Technology) cybersecurity in industrial environments. Given that many of these systems were historically isolated and not designed with modern cybersecurity in mind, what are the most effective strategies for protecting them against cyber threats? Additionally, how can industries strike a balance between maintaining operational efficiency and implementing robust security measures? If anyone has experience with specific tools or frameworks that have been successful in their organizations, sharing those insights would be really helpful.
