Instrumenting Competition-Based Exercises to Evaluate Cyber Defender Situation Awareness

Abstract

Cyber defense exercises create simulated attack and defense scenarios used to train and evaluate incident responders. The most pervasive form of competition-based exercise is comprised of jeopardy-style challenges, which compliment a fictional cyber-security event. Multiple competitions were instrumented to collect usage statistics on a per-challenge basis. The competitions use researcher-developed challenges containing over twenty attack techniques, which generate forensic evidence and observable second-order effects. The following observations were made: (1) a group of defenders performs better than an individual; (2) situation awareness of the fictional event may be measured; (3) challenge complexity does not imply difficulty. This research introduces a novel application of system instrumentation on competition-based exercises and describes an exercise development methodology for effective challenge and competition creation. Effective challenges correctly represent difficulty and reward competitors with objective points and optional forensic clues. Effective competitions compliment training goals and appropriately improve the knowledge and skill of a competitor.
