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.

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.

FieldDescription
TimeWindowCorrelate DLL file creation/modification with LSASS execution within a configurable timeframe (e.g., 5 min)
ImagePathPatternTune based on known legitimate LSASS plugin DLL paths
SignatureValidationFlag unsigned DLLs loaded into lsass.exe or those signed by unexpected publishers
RegistryKeyScopeScope to specific registry keys: HKLM\SYSTEM\CurrentControlSet\Control\Lsa\Authentication Packages
FileHashAllowListExclude known-good LSASS plugin DLLs based on cryptographic hash
