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, write | DC0061 File Modification |
| auditd:EXECVE | execve | 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 |
|---|---|
WatchedDirectories | Customize monitored directories (e.g., /usr/bin, /usr/sbin, /opt/apps) for binary tampering |
BaselineHashes | Maintain golden file hashes for integrity validation |
