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 | binary modified or replaced | DC0061 File Modification |
| macos:unifiedlog | execution of modified binary without valid signature | DC0032 Process 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 |
|---|---|
ApplicationPaths | Tune which application and library directories are monitored for tampering |
SignatureVerificationDepth | Define strictness of code-signing validation checks |
