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 |
|---|---|---|
| auditd:SYSCALL | execve | DC0032 Process Creation |
| linux:osquery | event-based | DC0059 File Metadata |
| desktop:file_manager | nautilus, dolphin, or gvfs logs | DC0055 File 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 |
|---|---|
ExtensionMismatch | Filter based on mismatched visible extension vs. magic bytes or mime-type |
ProcessLineage | Correlation between file open and subsequent script interpreter invocation |
FilenameEntropy | Suspicious Unicode sequences or byte entropy in filenames |
