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 | diskutil partitionDisk or eraseVolume with partition scheme modifications | DC0064 Command Execution |
| macos:unifiedlog | IOKit raw disk write to EFI/boot partition sectors | DC0046 Drive Modification |
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 |

AdminToolWhitelist | System provisioning workflows may legitimately re-partition disks; whitelist by context. |
