What is MITRE ATT&CK?
A knowledge base, published by the US non-profit research organization MITRE, of attacker techniques observed in real attacks. It organizes them into "tactics", which represent the attacker's goals (initial access, persistence, privilege escalation, lateral movement, exfiltration and so on), and "techniques", which represent the concrete methods for achieving them, and gives each technique an identifier. Defenders use it to check which techniques their detections and controls cover and to describe techniques in common terms in threat intelligence reports.
