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
StartupScriptNameFilename not matching expected initialization scripts.
ExecutionContextCommands run from unexpected SSH sessions or elevated shells.
PersistenceIntervalRare scheduling triggers (e.g., @reboot + hourly repetition).
