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
WatchedAppsTrack processes that normally should not upload data (e.g., Preview, Calculator).
EntropyThresholdHigh-entropy file uploads may indicate encrypted payloads designed for exfiltration.
