MITRE ATT&CK is a freely available, continuously maintained knowledge base about the behaviour of real attackers: tactics describe the goal of a step (such as initial access, privilege escalation, exfiltration), techniques the concrete methods for it — substantiated with observed cases and known groups.
The practical value lies in the shared language: when detection rules, reports and exercises reference the same technique IDs, gaps become visible and discussions precise.
How do you use ATT&CK in practice?
Defenders lay their detection and protection measures over the matrix: which techniques do we cover, where are we blind? This coverage view prioritises investments better than any gut feeling. Threat intelligence teams describe attacker groups by their typical techniques; red teams build realistic exercise scenarios from them.
The right expectation matters: ATT&CK is a catalogue, not an action plan. Complete coverage is neither possible nor necessary — the point is to consciously address the techniques relevant to your own risk profile.
What teams use ATT&CK for
- Gap analysis: assess and prioritise detection coverage per technique.
- Threat-informed defence: align protection with attacker methods observed in the wild.
- Purple team exercises: simulate attacks and verify detection technique by technique.
- Classify reports and incidents consistently — internally and with providers.
