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, write, unlink | DC0039 File Creation |
| linux:osquery | file_events.path | DC0059 File Metadata |
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 |
|---|---|
PathPrefix | Shared memory mount path used (e.g., /dev/shm/ or /run/shm/) |
FilenameRegex | Regex to match non-standard, suspicious, or encoded filenames |
ExecCorrelationWindow | Time window to correlate process execution from shared memory directories |
