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 sourceChannelData component

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
ServicePathRegexPath-based filters to identify service unit files or init scripts
UserContextListList of expected user contexts that normally perform service changes
CommandNameListBinaries used to register/modify services
