Abstract: 

Security Operations Centers (SOCs) not only employ various cyber defense technologies to continually monitor and control network traffic, but also rely heavily on cybersecurity analysts to make sense of the network monitoring data for attack detection and incident response. As the network monitoring data are usually generated at a rapid speed and contain a lot of noise, analysts are so far bounded by tedious and repetitive data triage tasks that they can hardly concentrate on in-depth analysis to generate timely and quality incident reports. These difficulties result in a great disparity in force between overwhelmed cybersecurity analysts and inspired attackers. Therefore, there is an urgent need to liberating cybersecurity analysts from the tedious data analytics to focus on the higher-level cyber situational awareness. Our work is aimed to reduce analysts' workloads by leveraging analysts' previous cognitive processes in data triage. We proposed an operation tracing method and captured the traces of analysts’ cognitive processes of data triage in an experiment. To utilize the captured traces, we developed an automated trace analysis method for constructing data triage rules from the traces. The rules are further used to build finite state machines for automated data triage. We evaluated the automated data triage systems constructed from the traces by applying them to a large dataset and comparing the data triage results with the ground truth.
