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 |
|---|---|---|
| macos:unifiedlog | Crash or abnormal termination of security agent or system extension host | DC0034 Process Metadata |
| macos:unifiedlog | Extension disabled, unloaded, failed to start | DC0074 Driver Metadata |
| NSM:Flow | Traffic spike preceding control crash | DC0085 Network Traffic Content |
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 |
|---|---|
ExtensionList | Protected security system extensions |
CrashBurstThreshold | Multiple failures in short interval |
