What type of connectivity is essential for Industrial Control Systems (ICS) monitoring?

1. Only wired connectivity

2. Both wired and wireless connectivity

3. Limited to site-specific connections

4. Strictly wireless with no external access

The correct answer is: Both wired and wireless connectivity

The essential connectivity for Industrial Control Systems (ICS) monitoring is both wired and wireless connectivity. This is due to the diverse operational environments and varying requirements of ICS. Wired connections are often more reliable and secure, making them suitable for critical systems that require consistent performance and low latency, such as those found in manufacturing and processing plants. These systems rely on wired networks to ensure stable communication between control devices, sensors, and monitoring systems. On the other hand, wireless connectivity is also vital in scenarios where mobility or flexible installation is necessary, such as in remote or hazardous locations where running cables is impractical. Wireless solutions can facilitate real-time data transmission from mobile assets or temporarily deployed sensors that need to be monitored without being constrained to fixed locations. Furthermore, the integration of both wired and wireless solutions enables a more robust and redundant system that can adapt to changing operational needs or unexpected situations, enhancing overall system resilience and flexibility in monitoring and controlling industrial processes. Other options, such as limiting connectivity to only wired, site-specific connections, or strictly wireless without external access, fail to account for the practical realities of modern ICS environments, where a hybrid approach is often the most effective solution.
