As IT and OT systems converge, organizations must navigate complex cybersecurity and privacy challenges to protect their integrated environments. Both David and Florian highlighted the critical importance of maintaining the security triad—Confidentiality, Integrity, and Availability (CIA)—to ensure that sensitive data is protected, accurate, and accessible:

• Confidentiality: Protecting sensitive data from unauthorized access is paramount, especially as IT/OT convergence involves the integration of operational and corporate data. Robust access controls, encryption, and secure data transmission are essential. Florian emphasized that, "Robust access controls and encryption are crucial to safeguarding data across both environments."

• Integrity: Ensuring the accuracy and reliability of data throughout its lifecycle is critical for operational decision-making. Data integrity must be maintained across both IT and OT environments to prevent manipulation or corruption that could lead to operational failures or security breaches. David noted, "Maintaining data integrity across connected systems prevents manipulation or corruption that could lead to operational failures or security breaches."

• Availability: Ensuring that systems and data remain accessible when needed is particularly vital in OT environments, where downtime can have costly and potentially dangerous consequences. Strategies should focus on balancing accessibility with robust security measures, such as deploying redundant systems and backup solutions.

The Growing Role of Edge Computing

Both David and Florian underscored the increasing importance of edge computing in enhancing data privacy and reducing costs. By processing data closer to its source, organizations can minimize latency, decrease the exposure of data to external threats, and comply more easily with data protection regulations. As David noted, "We are seeing more use of edge components than a year or two ago, especially as people start to accept the high costs of cloud computing."

Florian elaborated on the benefits of edge computing, stating that it "drastically decreases data protection requirements, compliance costs, and latency issues," making it a compelling alternative to centralized cloud processing.

Data Management Strategies: The Bronze-Silver-Gold Framework

David introduced the “Bronze-Silver-Gold” data management framework as a strategic approach to prioritize data management efforts:

• Bronze: Raw, unfiltered data that serves as the foundational layer.
