Security incidents not only produce trace evidence on host systems, but also leave traces throughout the devices and traffic flows within a network. The ability to analyze this trace evidence will allow incident response analysts to have a better understanding of what type of incident they are investigating, as well as potential actions that can be taken. This chapter addressed how to evaluate log files through the rapid process of blacklist comparison or DNS analysis to log analysis utilizing the Elastic Stack or other SIEM. Augmenting this primary method of network evidence evaluation was the inclusion of NetFlow analysis, and examining packet captures with Moloch and Wireshark. Network evidence is a critical component of incident investigation. This trace evidence, taken in conjunction with evidence obtained from potentially compromised websites, goes a long way in...
