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:EXECVE | curl or wget with POST/PUT options | DC0064 Command Execution |
| auditd:SYSCALL | open/read of sensitive directories (/etc, /home/*) | DC0055 File Access |
| NSM:Flow | sustained outbound HTTPS sessions with high data volume | DC0078 Network Traffic Flow |
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 |
|---|---|
MonitoredTools | Suspicious command-line utilities used for exfiltration (curl, wget, python). |
DataVolumeThreshold | Bytes transferred threshold per session to flag unusual uploads. |
