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 | file deletion | DC0040 File Deletion |
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 |
|---|---|
ServicePathMatch | Targets suspicious or orphaned unit files in /etc/systemd/system/ |
CronUserScope | Focus on crontab activity from root or uncommon users |
UserDeletionActivity | Looks for userdel or passwd deletion |
