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 | UpdateLoginProfile | DC0010 User Account Modification |
| AWS:CloudTrail | UpdateAccountPasswordPolicy | DC0069 Cloud Service 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.
