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 | open | DC0055 File Access |
| auditd:SYSCALL | execve | DC0032 Process Creation |
| auditd:SYSCALL | connect | DC0082 Network Connection 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 |
|---|---|
MonitoredToolsList | Define the list of steganographic or image-parsing tools to alert on (e.g., `steghide`, `imagemagick`) |
ScriptInterpreterMatch | Tune to detect script engines accessing media files (e.g., `python script.py image.png`) |
