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
SignedBinaryContextHelps to distinguish between signed/unsigned packed binaries (common in legitimate vs. malicious cases).
UserContextCan be used to scope to specific users or service accounts targeted in attacks.
