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:okta | Sign-in logs / audit events | 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 |
|---|---|
MFAFailureCount | Threshold of failed MFA attempts before alerting. |
RiskScoreThreshold | Custom threshold based on calculated identity risk. |
IPGeoVelocity | Detect impossible travel (logins from two distant geolocations within short time). |
