Cache side-channel attack is a common threat in cloud environments where caches are shared across co-located tenants. Detection of such attacks in real-time before the attack procedure is completed can enable cloud users to come up with a countermeasure and protect their privacy against these kinds of vulnerabilities. In this work, a real-time cache side-channel attack detection system for cloud systems is presented which leverages hardware performance counters. The combination of two neural networks is trained with long-term time sequences collected via hardware performance counters to learn the normal behavior of benign applications so that anomalies caused by attackers can be detected. This paper primarily examines the selection of best fit hardware performance counters for this purpose. Initial experiments are performed and time series feature extraction and selection methods are applied to preliminary results for the analysis.
