However, it is impossible to understand the scan details without using the correct filters.īelow are the base filters to probe Nmap scan behavior's on the network. It is essential to know how Nmap scans work to spot scan activity on the network. This section will cover identifying the most common Nmap scan types. As it is one of the most used network scanner tools, a security analyst should identify the network patterns created with it. Nmap is an industry-standard tool for mapping networks, identifying live hosts and discovering the services. This room will cover investigating packet-level details by synthesizing the analyst knowledge and Wireshark functionality for detecting anomalies and odd situations for a given case. For a security analyst, it is vital to stop and understand pieces of information spread in packets by applying the analyst's knowledge and tool functionality.
Now, it is time to investigate and correlate the packet-level information to see the big picture in the network traffic, like detecting anomalies and malicious activities. In the first two rooms, we have covered how to use Wireshark and do packet-level searches. Note that this is the third and last room of the Wireshark room trio, and it is suggested to visit the first two rooms stated below to practice and refresh your Wireshark skills before starting this one. In this room, we will cover the techniques and key points of traffic analysis with Wireshark and detect suspicious activities.
Learn the basics of traffic analysis with Wireshark and how to find anomalies on your network!
