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 |
| NSM:Flow | conn.log | DC0078 Network Traffic Flow |
| NSM:Flow | ssl.log | DC0085 Network Traffic Content |
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 |
|---|---|
UploadDirectionality | Bias detection toward sessions with larger upload vs download volume |
HostnameRegexList | List of known public Web services used for dead drops or C2 (e.g., GitHub, Twitter) |
ScriptParentName | Shell interpreter or automated job parent used for filtering (e.g., /usr/bin/python) |
