## What it is
The MITRE Cyber Analytics Repository (CAR) is a knowledge base of detection analytics based on the MITRE ATT&CK adversary model. Each analytic includes a hypothesis, pseudocode, implementation references for tools like Splunk and EQL, and unit tests to trigger detections.

## Use cases
- find detection analytics mapped to ATT&CK techniques
- implement adversary behavior detections in Splunk or EQL
- build threat hunting programs based on TTPs
- validate detection coverage against ATT&CK tactics and techniques
- get unit tests to trigger and verify analytics
- start a detection engineering program from community-validated content

## When to choose
- you need well-documented, validated detection analytics mapped to ATT&CK
- you want pseudocode and rationale for how detections work
- you are building or improving a threat detection or hunting capability
- you need unit tests to verify your detections fire

## When to avoid
- you need a turnkey SIEM or production detection product
- you require analytics for a tool not covered by CAR implementations
- you want exhaustive coverage of all ATT&CK techniques rather than a curated set

## Facets
- artifact type: dataset
- maturity: active
- function: security, monitoring, developer-tools
- domain: security
- platform: cross-platform
- tags: mitre-attack, detection-analytics, threat-hunting, knowledge-base, splunk, eql, threat-detection
