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 |
| auditd:SYSCALL | device event logs | DC0042 Drive 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 |
|---|---|
MountPointPattern | Monitor mount points like /media, /mnt, or /run/media. |
UserGroupScope | Restrict detection to non-root or unexpected users. |
AccessVolumeThreshold | Alert on large file access or copy events. |
