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 | Inotify watch creation or auditctl changes on /etc/cron* or /lib/systemd/system/ | DC0059 File Metadata |
| linux:syslog | Execution of non-standard script or binary by cron | DC0001 Scheduled Job Creation |
| auditd:SYSCALL | Execution of script interpreters by systemd timer (ExecStart) | DC0064 Command Execution |
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 |
|---|---|
ExecutablePathRegex | Regex defining suspicious binary/script paths triggered by cron/systemd |
WatchTargetPaths | Paths monitored by auditd/inotify for suspicious event registration |
