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:SysmonEventCode=11DC0039 File Creation
WinEventLog:SecurityEventCode=5145DC0102 Network Share Access
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
FilePathRegexRegex for matching key file extensions (.pem, .pfx, .ppk, etc.) or known certificate directories like C:\Users\*\.ssh\
ParentProcessNameSet of known benign certificate management tools to exclude (e.g., certutil.exe, ssh.exe)
