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
ShareNameOrganizations may use custom share paths outside of default C$, Admin$, etc.
ProcessNameCommon toolsets vary; defenders should tailor to unusual processes for their environment.
TimeWindowTime of day and access duration may need to be tuned to reduce false positives.
