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 |
|---|---|---|
| saas:googledrive | drive.permission.add | DC0023 Cloud Storage Modification |
| saas:box | collaboration.invite | DC0027 Cloud Storage Metadata |
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 |
|---|---|
UserContext | Whether the user is in a high-privileged or VIP group |
