This paper proposes a novel trace clustering approach for workflow mining to allow for security audits that regard the evolution of process models along time. Specifically, the trace-clustering method allows auditors to distinguish between different “active” process variants within a timeframe, thereby allowing the visualization of the process evolution. Separately analyzing subsequent process variants allows auditors to localize time-frames and corresponding models for identified vulnerabilities and thus more sophisticated security audits.
