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, writeDC0061 File Modification
auditd:SYSCALLexecveDC0032 Process Creation
NSM:FlowOutbound HTTP/SDC0085 Network Traffic Content

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
TargetPathsSuspicious write locations such as /tmp/, ~/Downloads/
ExecutionContextProcesses spawned by browsers or svg-viewing apps that invoke interpreters
NetworkDestinationsURLs/IPs contacted post-SVG access – may reflect initial C2
