How Benchmarks and Evaluation Protocols Shape Conclusions in Provenance-Based Intrusion Detection

Excerpt

arXiv:2608.01454v2 Announce Type: replace-cross Abstract: Provenance-based intrusion detection systems (PIDS) frequently report strong performance, but the conclusions drawn from these results can be highly sensitive to benchmarking choices and evaluation protocols. We investigate this dependency by re-evaluating representative PIDS on public datasets that meet our audit, labeling, and calibration requirements. Focusing primarily on the audited DARPA TC E3 datasets, we apply a unified protocol w
