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 | write | DC0061 File Modification |
| auditd:SYSCALL | execve | DC0032 Process Creation |
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 |
|---|---|
CronFilePath | System-specific crontab paths may vary across distros or deployments. |
RunUser | Define if only root or specific admin users are allowed to schedule jobs. |
ExecutionFrequency | Threshold for suspicious repetition (e.g., every minute jobs). |
