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 | CreateUser | DC0014 User Account Creation |
| AWS:CloudTrail | AttachUserPolicy | DC0010 User Account Modification |
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 |
|---|---|
Region | Alert when creation happens in unexpected regions |
TimeWindow | Chain CreateUser → AttachPolicy → AccessKey within short timeframe |
UserAgent | Monitor API calls from non-console or automation tools |
