What tool did Justin deploy for monitoring and ensuring the reliability of OT systems?

Wireshark
Flowmon
Nessus
Snort

The correct answer is: Flowmon

Flowmon is a sophisticated monitoring and analysis tool specifically designed for operational technology (OT) systems. It excels in providing visibility into network traffic, enabling organizations to ensure their systems remain reliable and secure. Through the use of flow data, Flowmon allows for the real-time monitoring of network performance and the identification of potential issues that could affect the reliability of OT systems. In contrast, Wireshark is a packet analyzer that is primarily used for deep packet inspection and is more suited for detailed troubleshooting rather than ongoing monitoring. Nessus is a vulnerability scanner that focuses on identifying security flaws rather than monitoring operational integrity. Snort is an intrusion detection system widely used for network security and can alert on suspicious activity, but it does not provide the same level of performance monitoring and analysis that Flowmon offers specifically for OT environments. Thus, Flowmon is the ideal choice in this context due to its tailored features that support the reliability of OT systems.
