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
WinEventLog:SystemEventCode=7045DC0060 Service Creation
WinEventLog:SecurityEventCode=4698DC0001 Scheduled Job Creation
WinEventLog:SysmonEventCode=1DC0032 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
TaskNameSimilarityThresholdSimilarity threshold for comparing new task/service names to known legitimate names (e.g., Levenshtein distance)
BinaryReputationScoreConfidence level required for allowing a binary, often from unsigned or untrusted source
ExecutionContextWhether the execution came from SYSTEM, service accounts, or user contexts
