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 |
|---|---|---|
| WinEventLog:Application | High-frequency errors or hangs from resource-intensive application components (e.g., .NET, IIS, Office Suite) | DC0038 Application Log Content |
| WinEventLog:Sysmon | EventCode=1 | DC0032 Process Creation |
| Windows:perfmon | Sudden spikes in CPU/Memory usage linked to specific application processes | 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 |
|---|---|
CPUThreshold | Define what percentage of CPU usage indicates abnormal behavior. |
MemoryConsumptionWindow | Window (e.g., 5 mins) during which sustained memory usage may be abnormal. |
AppCrashFrequency | Threshold for frequency of application faults within a specific interval. |
