The document discusses MITRE's efforts to map security techniques from the Adversarial Tactics, Techniques, & Common Knowledge (ATT&CK) framework to common security control frameworks. It describes challenges with existing mapping efforts and MITRE's goals to create a centralized, trusted resource for ATT&CK-control mappings that can help organizations assess security effectiveness and capability gaps. MITRE is seeking input on desired mappings and contributions from the community to collaborate on this initiative.
