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, setifflags | DC0032 Process Creation |
| auditd:SYSCALL | promiscuous mode transitions (ioctl or ifconfig) | DC0064 Command Execution |
| networkconfig | interface flag PROMISC, netstat | ip link | ethtool | 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 |
|---|---|
InterfaceList | Limit analysis to external interfaces (e.g., eth0, wlan0) and exclude virtual adapters. |
PromiscuousSessionThreshold | Raise alerts if interface remains in PROMISC longer than threshold duration. |
