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 calls modifying local mail filter configuration files | DC0064 Command Execution |
| ApplicationLog:MailServer | Unexpected additions of sieve rules or filtering directives | DC0038 Application Log Content |
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.
