“Squert is a web application that is used to query and view event data stored Server that delivered malware to the Windows VM. In this section, you’ll examine the network traffic for a Windows VM thatīrowsed to a compromised website that in turn referred the Windows VM to a To learn more about YAF and SILK, you can find additional material on Part 2: Examining PCAP Files There are many other filters that we can use to analyze network traffic, especially for incident response purposes. Reflect: Conceptually, why should we look for long standing SSH connections? Then the -percentage flag filtersīased on ranked group aggregate values for, in this case, -bytes. The -fields conceptually performsĪ “group-by” on the incoming rwfilter data for, in this case, unique sip,dip pairs. Two comprised at least 1% of total network byte traffic. The -percentage=1 flag specifies that we only want to retain a sip,dip pair if total bytes exchanged between the.For example, when the ssh command is run to connect to an sshd service listening on another computer, the connecting computer is the “source,” and the connection target is the “destination.” The sip and dip fields stand for source and destination IP respectively.Īll network traffic records have “sources” and “destinations.” To understand “source” and “destination” terminology, consider the client-server architecture pattern. See the wikipedia page on IP protocols for a list of IP protocols and their numbers. The - at the end of -protocol=0- indicates that all protocols from 0 and above.This command uses rwfilter to parse the source data, and then calculates statistics on that data using rwstats.The backslash " \" character lets a single command span multiple lines.
