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, connect | DC0032 Process Creation |
| iptables:LOG | OUTBOUND | 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 |
|---|---|
BinaryPath | Tune for suspicious binaries like curl, wget, python, netcat |
IPDistance | Detect multiple different external IPs contacted within short timeframe |
