Automated Detection of Spectre and MeltdownAttacks using Explainable Machine Learning

Spectre and Meltdown attacks exploit security vulnerabilities of advanced architectural features to access inherently concealed memory data without authorization. Existing defense mechanisms have three major drawbacks: (i) they can be fooled by obfuscation techniques, (ii) the lack of transparency severely limits their applicability, and (iii) it can introduce unacceptable performance degradation.

In this paper, we propose a novel detection scheme based on explainable machine learning to address these fundamental challenges. Specifically, this paper makes three important contributions. (1) Our work is the first attempt in applying explainable machine learning for Spectre and Meltdown attack detection. (2) Our proposed method utilizes the temporal differences of hardware events in sequential timestamps instead of overall statistics, which contributes to the robustness of ML models against evasive attacks. (3) Extensive experimental evaluation demonstrates that our approach can significantly improve detection efficiency (38.4% on average) compared to state-of-the-art techniques.
