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, read | DC0055 File Access |
| auditd:SYSCALL | Kernel Device Events - USB Block Devices | 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 |
|---|---|
MountPath | Look for /media/, /mnt/, /run/media/ paths associated with removable storage. |
CopyCommandSignature | Detect rsync, cp, tar, zip activity writing to USB mount point. |
AccessRateThreshold | Define abnormal access patterns (e.g., >100 files in <5 min). |
