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 | SecurityAgentPlugins modification | DC0061 File Modification |
| macos:osquery | process_open | DC0035 Process Access |
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 |
|---|---|
PluginPaths | List of approved authentication plugin directories to baseline. |
