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
ParentProcessListParent processes expected to execute child processes (e.g., Office apps).
MacroExecutionThresholdThreshold for number of macros executed before raising alerts.
