Abstract

In 2010, IT-security experts from northern European governments and organizations gathered to conduct the first of a series of NATO-led cyber-defense exercises in a pilot attempt of training cyber defense. To gain knowledge on how to assess team effectiveness in cyber-defense exercises, this case study investigates the role of behavioral assessment techniques as a complement to task-based performance measurement. The collected data resulted in a massive data set including system logs, observer reports, and surveys. Six different methods were compared for feasibility in assessing the teams’ performance, including automated availability check, exploratory sequential data analysis, and network intrusion detection system attack analysis. In addition, observer reports and surveys were used to collect aspects relating to team structures and processes, aiming to discover whether these aspects can explain differences in effectiveness. The cross-disciplinary approach and multiple metrics create possibilities to study not only the performance-related outcome of the exercise, but also why this result is obtained. The main conclusions found are (1) a combination of technical performance measurements and behavioral assessment techniques are needed to assess team effectiveness, and (2) cyber situation awareness is required not only for the defending teams, but also for the observers and the game control.
