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
auditd:SYSCALLopen, read, mountDC0055 File Access
journald:systemdudisks2 or udevd logsDC0042 Drive Creation
auditd:SYSCALLexecveDC0032 Process Creation

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
MountPathRegexFilter for unexpected or user-defined mount locations (e.g., /media/usb*)
AccessMaskTune based on read/write access types seen during collection
