Certified Incident Handler (CIH) Practice Ecam

What tool did Ramos deploy to detect malfunctioning of various ICS devices and security incidents in the ICS network?

1. Flowmon

2. Wireshark

3. NetworkMiner

4. Malcolm

The correct answer is: Flowmon

The choice of Flowmon as the tool deployed by Ramos to detect malfunctioning of various Industrial Control System (ICS) devices and security incidents in the ICS network is particularly fitting due to its design and capabilities. Flowmon excels in traffic analysis and network monitoring, which are crucial for maintaining the operational integrity of ICS environments. It offers features such as anomaly detection, performance monitoring, and visibility into network flows, which can aid in identifying both operational malfunctions and potential security incidents. This tool is tailored for environments like ICS where monitoring the behavior of devices connected to the network is essential. It helps in uncovering irregularities that may indicate a malfunction or an attack, thus enabling timely responses to mitigate risks. Overall, Flowmon is well-suited for enhancing situational awareness and ensuring the reliability of ICS networks. Other tools like Wireshark are primarily utilized for packet analysis and troubleshooting network issues but may not offer the same level of proactive monitoring for ICS-specific vulnerabilities. Similarly, NetworkMiner and Malcolm have their own specific use cases but do not provide the comprehensive suite of tools for both performance and security monitoring in an ICS context that Flowmon does.
