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, rename | DC0061 File Modification |
| auditd:SYSCALL | execve | DC0032 Process Creation |
| linux:osquery | crontab, systemd_timers | DC0001 Scheduled Job 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 |
|---|---|
CronSchedulePattern | Look for high-frequency or off-hour scheduling patterns. |
ServiceUser | Unusual users scheduling jobs (e.g., www-data, nobody). |
BinaryEntropy | Abnormal scripts or binaries tied to the scheduled job. |
