The landscape of cyber threats against AI and ML systems is ever-evolving, with dire consequences for industries that increasingly rely on these technologies. Staying abreast of the adversary's tactics and techniques is crucial. The MITRE ATLAS framework offers an invaluable resource for understanding the modus operandi of cyber adversaries. In this talk, I will introduce the MITRE ATLAS framework/knowledge base, delving into its background, structure, and its practical utility for cyber defense of these technologies. The focus will be on the growing catalog of techniques documented in the framework, which provides insights into the specific actions adversaries take to achieve their objectives. Through real-world examples and case studies, attendees will gain an understanding of how to leverage the ATLAS framework to fortify their organization's security posture against the escalating AI and ML threats. This talk is ideal for cybersecurity professionals, AI and ML practitioners, and policymakers.
