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 |
| auditd:SYSCALL | connect | DC0082 Network Connection Creation |
| auditd:SYSCALL | open | DC0055 File Access |
| auditd:SYSCALL | write | DC0061 File Modification |
| NSM:Flow | NetFlow/Zeek conn.log | 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 |
|---|---|
ProtocolType | Flag unexpected protocols (e.g., HTTP on port 53 or FTP traffic from non-standard tools). |
UserContext | Scope for privilege escalation or service account behavior. |
FileExtensionSensitivity | Track movement of file types of interest (e.g., `.csv`, `.sql`, `.key`). |
