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
RegexPatternsPatterns like password, secret, token can be expanded or customized
UserContextScopeScope of users monitored (e.g., root vs all users)
TimeWindowTime between suspicious file access and credential use
