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
CommandLineTune for dscl -list, dscacheutil -q user, id -un, etc.
ExecutionContextAlert if enumeration is performed in non-console session or by unusual users.
