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,AssumeRoleWithSAML,AssumeRoleWithWebIdentity | DC0067 Logon Session Creation |
| AWS:CloudTrail | CreateUser|AttachRolePolicy|CreateAccessKey|UpdateAssumeRolePolicy|CreateLoginProfile | DC0038 Application Log Content |

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 |
|---|---|
ExternalAccountAllowList | Cross-account principals permitted to assume roles; used for allow-listing. |
SensitiveAPIs | Provider-specific list of risky APIs for scoring. |
GeoVelocityThreshold | Detect impossible travel between partner and tenant actions. |
