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:Security | EventCode=4688 | DC0032 Process Creation |
| WinEventLog:Sysmon | EventCode=7 | DC0016 Module Load |
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 |
|---|---|
AllowedCertificateAuthorities | Define trusted issuers to suppress noise from legitimate enterprise signing chains |
TimeWindow | Correlation window for detecting execution of binaries with newly observed or anomalous certificates |
CertificateAgeThreshold | Baseline normal age of certificates; flag very recent or expired certificates |
