Query: A Model-Based Approach to Anomaly Detection Trading Detection Time and
  False Alarm Rate   The complexity and ubiquity of modern computing systems is a fertile ground
for anomalies, including security and privacy breaches. In this paper, we
propose a new methodology that addresses the practical challenges to implement
anomaly detection approaches. Specifically, it is challenging to define normal
behavior comprehensively and to acquire data on anomalies in diverse cloud
environments. To tackle those challenges, we focus on anomaly detection
approaches based on system performance signatures. In particular, performance
signatures have the potential of detecting zero-day attacks, as those
approaches are based on detecting performance deviations and do not require
detailed knowledge of attack history. The proposed methodology leverages an
analytical performance model and experimentation and allows to control the rate
of false positives in a principled manner. The methodology is evaluated using
the TPCx-V workload, which was profiled during a set of executions using
resource exhaustion anomalies that emulate the effects of anomalies affecting
system performance. The proposed approach was able to successfully detect the
anomalies, with a low number of false positives (precision 90%-98%).
