Overview

Machine learning has seen a remarkable rate of adoption in recent years across a broad spectrum of industries and applications. Many applications of machine learning techniques are adversarial in nature, insofar as the goal is to distinguish instances which are ``bad'' from those which are ``good''. Indeed, adversarial use goes well beyond this simple classification example: forensic analysis of malware which incorporates clustering, anomaly detection, and even vision systems in autonomous vehicles could all potentially be subject to attacks. In response to these concerns, there is an emerging literature on adversarial machine learning, which spans both the analysis of vulnerabilities in machine learning algorithms, and algorithmic techniques which yield more robust learning.
This tutorial will survey a broad array of these issues and techniques from both the cybersecurity and machine learning research areas. In particular, we consider the problems of adversarial classifier evasion, where the attacker changes behavior to escape being detected, and poisoning, where training data itself is corrupted. We discuss both the evasion and poisoning attacks, first on classifiers, and then on other learning paradigms, and the associated defensive techniques. We then consider specialized techniques for both attacking and defending neural network, particularly focusing on deep learning techniques and their vulnerabilities to adversarially crafted instances.
