Log sources and channels
Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.
| Log source | Channel | Data component |
|---|---|---|
| macos:unifiedlog | com.apple.diskarbitration | DC0042 Drive Creation |
| fs:fsusage | open/write/exec calls | DC0039 File Creation |
Mutable elements
Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.
| Field | Description |
|---|---|
VolumeNameFilter | Known suspicious USB volume labels or types (e.g., NO NAME, SECUREDATA). |
ProcessContext | Unusual processes accessing USB drives (e.g., bash, Python, unsigned binaries). |
