What tool helps incident responders monitor and analyze network traffic?

1. OmniPeek

2. WireShark

3. Tcpdump

4. Pcap

The correct answer is: OmniPeek

The correct choice for a tool that helps incident responders monitor and analyze network traffic is WireShark. This application is widely recognized in the field of network analysis and is particularly beneficial for incident response scenarios. WireShark provides a user-friendly interface that allows responders to capture and view the details of network traffic in real-time or from previously saved capture files. It supports a vast array of protocols and offers powerful filtering capabilities, enabling responders to isolate and examine specific packets of interest. This detailed analysis assists in identifying suspicious behavior, unauthorized access, or potential security incidents within the network. While other tools like OmniPeek, Tcpdump, and Pcap have their own merits, WireShark's extensive protocol support and analysis features make it a preferred choice among incident responders for monitoring and analyzing network traffic. Tcpdump, for instance, is a command-line tool for packet capturing while Pcap refers to the packet capture format that is used by various network analysis tools, including WireShark. OmniPeek, while useful, is less commonly referenced than WireShark in many incident response contexts.
