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 | open | DC0055 File Access |
| linux:syslog | postfix/smtpd | DC0082 Network Connection Creation |
| linux:osquery | process_events | DC0032 Process 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 |
|---|---|
WatchedMailDirs | Specify user mail directories (/var/mail, ~/Maildir) |
ProcessNameList | Tune based on local mail clients or curl usage in environment |
TimeWindow | Define how close together access and exfil events must occur |
