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 | unlink/unlinkat | 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 |
|---|---|
MailFolderPath | Common inbox file locations like /var/spool/mail/, /var/mail/ |
CommandPattern | Usage of mailx or echo piped to mail followed by deletion |
