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 |
| linux:osquery | Read headers and detect MIME type mismatch | DC0059 File Metadata |
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 |
|---|---|
benign_extensions | Linux-targeted masquerade extensions (.jpg, .pdf, .png) |
HeaderInspectionEnabled | Whether to parse file signatures or MIME types from file headers |
ExecPathScope | Monitored directory scope for adversarial execution (e.g., /tmp/, /home/username/Downloads) |
