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:CloudWatch | Elevated 5xx response rates in application logs or gateway layer | DC0038 Application Log Content |
| AWS:CloudTrail | InvokeFunction | DC0070 Cloud Service Metadata |
| AWS:CloudMetrics | Autoscaling, memory/cpu alarms, or instance unhealthiness | DC0018 Host Status |
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 |
|---|---|
HTTP5xxRateThreshold | Ratio of 5xx error codes over requests indicating resource exhaustion. |
FunctionInvocationRate | Spike in lambda/API gateway executions indicating scripted behavior. |
AutoscaleEventCount | Triggers linked to app DoS where legitimate scaling is mimicked. |
