Ethical Hacking Essentials Practice Test

What tool was employed by Clark to protect the IoT infrastructure?

1. Network Firewall

2. FortiNAC

3. Antivirus Software

4. Intrusion Detection System

The correct answer is: FortiNAC

The selection of FortiNAC as the tool used by Clark to protect the IoT infrastructure reflects its specific capabilities tailored for managing and securing network access for various connected devices. FortiNAC stands for Fortinet Network Access Control, which specializes in maintaining visibility and control over all devices connected to the network, making it ideal for environments with many Internet of Things (IoT) devices. This tool provides several key features relevant to IoT infrastructure, such as device identification, compliance enforcement, and real-time monitoring of device behavior. By effectively managing access to the network and ensuring that only authorized devices can connect, FortiNAC helps mitigate risks associated with unauthorized access and potential vulnerabilities in IoT devices. In contrast, while a network firewall provides perimeter defense against external attacks, it does not specifically focus on the unique challenges posed by numerous IoT devices. Antivirus software primarily protects against malware and malicious software but may not address network access and device management comprehensively. An intrusion detection system (IDS) is useful for identifying threats after they penetrate the network but doesn't inherently manage access for IoT devices in a proactive manner. Therefore, FortiNAC serves as a specialized and effective solution for securing IoT infrastructure, which is why it is the appropriate answer
