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 |
|---|---|---|
| AWS:CloudTrail | AssumeRole, GetFederationToken, GetSessionToken | DC0007 Web Credential Usage |
| AWS:CloudTrail | sts:GetFederationToken | DC0002 User Account Authentication |
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 |
|---|---|
GeoIPDistanceThreshold | Distance between token creation and resource use locations |
RoleScope | Limit scope of acceptable role assumptions by account type |
