Understanding ATT&CK
MITRE ATT&CK is the universal language for describing adversary behavior. It transforms security from guesswork to a structured, measurable discipline.
Why ATT&CK Matters
- Common Language: Describe threats consistently
- Gap Analysis: Identify detection coverage gaps
- Threat Intel: Map actors to techniques
Attack Chain Example
Ransomware Kill Chain
Initial Access
Phishing, exploits, supply chain
Execution
Scripts, commands, malware
Persistence
Registry, services, scheduled tasks
Impact
Encryption, destruction, defacement
Coverage Maturity
ATT&CK Maturity Levels
Level 1: Basic
<25% technique coverage, manual analysis, limited detections
Level 2: Developing
25-50% coverage, some automation, growing detection library
Level 3: Defined
50-75% coverage, integrated workflow, regular testing
Level 4: Optimized
>75% coverage, threat intelligence driven, continuous improvement

Quick Start
Start with high-prevalence techniques like T1059 (Command Scripting), T1566 (Phishing), and T1078 (Valid Accounts). These cover the most common attack vectors.
Conclusion
ATT&CK transforms security operations from reactive to proactive. By mapping defenses to known adversary behavior, organizations can systematically close gaps and measure improvement.
