Researchers have developed an explainable AI framework aimed at improving network intrusion detection systems (NIDS). This framework integrates SHAP-based feature attribution with a semantic interpretation layer, allowing for better human-readable explanations of model behavior. Evaluations were conducted using the UNSW-NB15 and CIC-IDS2017 datasets, achieving high agreement between model rules and SHAP evidence. The framework retained 67 rules for UNSW-NB15 and 86 for CIC-IDS2017, with strong semantic coverage. However, the study emphasizes that high classification performance does not guarantee reliable post-hoc explanations. The findings suggest that explanation reliability should be assessed alongside feature rankings and perturbation controls. The research highlights the importance of rigorous evaluation methods in AI-driven cybersecurity tools.
