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
MountPathPatternTypical mount paths to monitor (e.g., /media/usb*, /run/media/username/*).
TimeWindowBetweenHostsTunable detection window to correlate read/write between different hosts within a short interval (e.g., <15m).
