Abstract
With the advances in machine learning (ML) and deep learning (DL) techniques, and the potency of cloud computing in offering services efficiently and cost-effectively, Machine Learning as a Service (MLaaS) cloud platforms have become popular. In addition, there is increasing adoption of third-party cloud services for outsourcing training of DL models, which requires substantial costly computational resources (e.g., high-performance graphics processing units (GPUs)). Such widespread usage of cloud-hosted ML/DL services opens a wide range of attack surfaces for adversaries to exploit the ML/DL system to achieve malicious goals. In this article, we conduct a systematic evaluation of literature of cloud-hosted ML/DL models along both the important dimensions—attacks and defenses—related to their security. Our systematic review identified a total of 31 related articles out of which 19 focused on attack, six focused on defense, and six focused on both attack and defense. Our evaluation reveals that there is an increasing interest from the research community on the perspective of attacking and defending different attacks on Machine Learning as a Service platforms. In addition, we identify the limitations and pitfalls of the analyzed articles and highlight open research issues that require further investigation.
Highlights
In recent years, machine learning (ML) techniques have been successfully applied to a wide range of applications, significantly outperforming previous state-of-the-art methods in various domains: for example, image classification, face recognition, and object detection
These articles were categorized into three classes, that is, articles that are focused on attacks, articles that are focused on defenses, and articles that considered both attacks and defenses containing 19, 6, and 6 articles each, respectively
We presented a systematic review of literature that is focused on the security of cloud-hosted ML/deep learning (DL) models, named as Machine Learning as a Service” (MLaaS)
Summary
Machine learning (ML) techniques have been successfully applied to a wide range of applications, significantly outperforming previous state-of-the-art methods in various domains: for example, image classification, face recognition, and object detection. These ML techniques—in particular deep learning (DL)–based ML techniques—are resource intensive and require a large amount of training data to accomplish a specific task with good performance. Keeping in mind the cost of GPUs/Tensor Processing Units and the fact that small businesses and individuals cannot afford such computational resources, the training of deep models is typically outsourced to clouds, which is referred to in the literature as “Machine Learning as a Service” (MLaaS).
