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 | socket: Suspicious creation of AF_UNIX sockets outside expected daemons | DC0032 Process Creation |
| auditd:SYSCALL | open: Access to named pipes or FIFO in /tmp or /dev/shm by unexpected processes | DC0055 File Access |
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 |
|---|---|
SocketPathBaseline | Expected UNIX socket paths used by system services and applications. |
FIFOAccessPatterns | Legitimate processes expected to open pipes in shared directories. |
