Answer:
The answer is "Develop and implement security and resilience programs for the critical infrastructure under their control, while taking into consideration the public good as well".
Explanation:
In the past, industrial control systems were generally not connected to IT networks and did not contain complex computing capabilities; therefore, they could be adequately protected using physical security measures like locks and fences. However, as OT has become more integrated with IT, such physical measures are becoming less adequate in securing the underlying critical assets.
