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 | write | DC0061 File Modification |
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 |
|---|---|
AtJobPath | Monitoring additional paths (e.g., tmp-mounted spool dirs) for modified at jobs. |
ScheduleLatency | Expected delay between at job creation and execution. |
JobScriptEntropy | High entropy or obfuscation in at job payloads. |
