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 | GetCallerIdentity | DC0007 Web Credential Usage |
| AWS:CloudTrail | AssumeRole | DC0013 User Account 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 |
|---|---|
TokenReuseWindow | Time window where token reuse is suspicious |
RoleMismatchAlerting | Enable if tokens for RoleA are used in resources only RoleB should access |
