AI-Driven Software Supply Chain Security and Risk Assessment

The growing complexity of software ecosystems has made the Software Supply Chain (SSC) a primary target for cyberattacks, as evidenced by SolarWinds, Log4Shell, and the XZ Utils backdoor. Traditional Software Composition Analysis (SCA) and static scanning tools are reactive and poorly suited to detecting novel or prove...

Explainable Artificial Intelligence-Based Intrusion Detection for Zero-Day Cyber Attacks: A Hybrid Transformer–Long Short-Term Memory Framework with SHapley Additive exPlanations and Local Interpretable Model-Agnostic Explanations Interpretability

The findings indicate that embedding explainability directly into the zero-day detection pipeline, rather than treating it as an auxiliary diagnostic layer, materially improves both detection robustness and analyst-facing transparency without incurring prohibitive computational overhead.
