A new research paper published on arXiv explores how the choice of benchmarks and evaluation protocols significantly influences the conclusions drawn about provenance-based intrusion detection systems (PIDS). The study re-evaluates several PIDS using a unified protocol on DARPA TC E3 datasets, revealing that alerting success can diverge from investigation utility, with some systems failing to provide sufficient context for forensic analysis. The research also found that simple allowlists often matched or exceeded the performance of more complex learned baselines, suggesting that many reported PIDS successes may be due to lexical novelty rather than advanced modeling. The paper emphasizes that PIDS architectural claims should be interpreted in conjunction with the specific benchmark properties and evaluation methods used. AI
