Why are safety constraints a critical aspect of the OT environment for ICS?

To reduce the cost of software licenses

To protect personnel, equipment, and the environment from harm

To improve the speed of internet browsing

To ensure data is encrypted during transmission

A food processing plant is designing a new control system. The safety engineer insists that the system must include emergency stop circuits that are hardwired and independent of the network. What is the primary reason for this requirement?

To comply with IT security policies

To reduce the cost of network infrastructure

To ensure safety functions operate even if the control network fails

To allow remote monitoring of emergency stops

A cybersecurity analyst is assessing a chemical plant's control network. The analyst proposes encrypting all traffic between the HMI and the PLC. The control engineer objects, stating that encryption could introduce latency and complicate troubleshooting. What is the most important factor to consider before implementing encryption?

The preference of the IT department

The real-time requirements of the control loop and the potential for latency

The compatibility with legacy protocols

The cost of encryption hardware

A natural gas pipeline company is updating its leak detection system. The current system uses a SCADA system with remote terminal units (RTUs) that poll pressure sensors every second. The company wants to add a new analytics server that will process the data to predict leaks. The analytics server is a commercial off-the-shelf (COTS) server running a modern OS. The security team wants to install antivirus and apply monthly patches. The operations team is concerned about the impact on the SCADA system. What is the best approach?

Replace the RTUs with modern ones that support encryption

Place the analytics server on a separate network segment and use a data diode to receive data from the SCADA system

Install the analytics server directly on the SCADA network and disable antivirus to avoid interference

Run the analytics server on a virtual machine on the same hardware as the SCADA server
