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 |
|---|---|---|
| CloudTrail:PutObject | PutObject | DC0039 File Creation |
| AWS:CloudTrail | GetObject, CopyObject | DC0025 Cloud Storage Access |
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 |
|---|---|
BucketNameRegex | Patterns of S3 or GCP buckets used for static website hosting may vary by organization. |
IAMRoleContext | Some uploads may appear benign unless enriched with user/role metadata. |
