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 | log stream | DC0064 Command Execution |
| macos:endpointsecurity | es_event_exec | DC0032 Process Creation |
| macos:unifiedlog | memory mapping | 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 |
|---|---|
ScriptContent | Encoded payload content varies across adversaries. |
ExecutionChain | Sequence of tools or scripts executed can differ. |
UserContext | May depend on whether user is admin, daemon, or system account. |
