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 |
| linux:Sysmon | EventCode=1 | DC0032 Process Creation |
| auditd:SYSCALL | write | DC0039 File 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 |
|---|---|
ExecutableName | Capture binaries like arecord, parecord, or ffmpeg. |
DevicePath | Log attempts to access /dev/snd/*, /dev/dsp, /proc/asound/*. |
UserContext | Whether the user has audio access rights or is running under elevated privileges. |
