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
PathRegexPattern matching known attacker staging directories or hidden file paths.
TimeWindowDeletion shortly after process execution or privilege escalation.
SecureDeletionToolUncommon presence or use of `shred`, `wipe`, or `srm`.
