A manufacturing company is integrating its operational technology (OT) network with its information technology (IT) network to improve efficiency and data analytics. The information security manager recognizes the unique security challenges presented by OT environments. What is the PRIMARY concern when securing this converged IT/OT environment?
- APreventing intellectual property theft from the IT network impacting manufacturing processes.
- BEnsuring data privacy for customer information processed across the integrated network.
- CManaging the increased volume of log data generated by the converged infrastructure.
- DMaintaining the availability and integrity of critical industrial control systems (ICS).
Show answer & explanationAnswer & explanation
Correct answer: D. Maintaining the availability and integrity of critical industrial control systems (ICS).
In OT environments, the primary concern is always the safety, availability, and integrity of physical processes and industrial control systems (ICS). A breach in OT can lead to physical damage, environmental harm, or loss of life, making these concerns paramount over typical IT concerns like data privacy or intellectual property theft. The convergence increases the attack surface for these critical systems.
Why the other options are wrong
- A. Intellectual property theft is an important IT concern, but it does not carry the same safety and operational criticality as ICS integrity.
- B. Data privacy is an important IT concern, but availability and integrity of physical processes are paramount in OT.
- C. Managing log data volume is an operational challenge, not the primary security concern for the converged environment's core mission.
IT/OT Convergence Security
The integration of Information Technology (IT) and Operational Technology (OT) systems, requiring a security strategy that addresses the unique risks and priorities of both domains.
- OT prioritizes safety and availability.
- IT prioritizes confidentiality, integrity, availability (CIA).
- Convergence expands attack surface.
Memory trick: OT's heart is availability; IT's is data.
