Audit reveals flaws in CAGE 4 cyber-defense benchmark scoring

A new audit of the CAGE 4 benchmark, used for evaluating learned cyber-defense agents, reveals significant issues with its scoring and methodology. The research indicates that the simulator silently discards actions, leading to inflated scores, and that the evaluation process seeds the environment but not the policy, making reported means unreliable. Furthermore, the study highlights inconsistencies in recovery precision and a lack of clarity in published comparison tables regarding the artifacts, sampling, and criteria used. The researchers are releasing their findings, code, and a disclosure checklist to address these concerns. AI

IMPACT Highlights critical issues in evaluating AI-driven cyber-defense systems, potentially impacting the reliability of future security benchmarks.

    What a CAGE 4 Score Measures: An Audit of a Learned Cyber-Defense Benchmark, Its Reference Defenders, and the Tables Built on Them

    arXiv:2611.14068v1 Announce Type: cross Abstract: CAGE Challenge 4 is the benchmark on which learned multi-agent cyber defenders are compared. We reproduce its two reference defenders, KEEP and H-MARL Expert, in a pinned container and show that three things read from it measure l…
