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 | process::exec | DC0032 Process Creation |
| macos:endpointsecurity | ES_EVENT_MMAP | DC0020 Process 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 |
|---|---|
SignedBinaryContext | Helps to distinguish between signed/unsigned packed binaries (common in legitimate vs. malicious cases). |
UserContext | Can be used to scope to specific users or service accounts targeted in attacks. |
