Walkthroughs for MITRE ATLAS™ and atlas.mitre.org/. ATLAS enables researchers to navigate the landscape of threats to artificial intelligence (AI) and machine learning (ML) systems. Modeled after the MITRE ATT&CK® framework, ATLAS is a knowledge base of adversary tactics, techniques, and case studies for AI/ML systems based on real-world observations, demonstrations from red teams and security groups, and the state of the possible from academic research. Join our collaborative community to shape future tool and framework developments in AI security, threat mitigation, bias, privacy and other critical aspects of AI assurance at atlas.mitre.org/resources/contact.
