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 source | Channel | Data component |
|---|---|---|
| WinEventLog:Security | EventCode=4688 | DC0032 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.
| Field | Description |
|---|---|
CommandLineEntropyThreshold | Used to flag base64 or token-heavy command-line strings |
SuspiciousCharacterCount | Escape character and symbol frequency in command-line strings |
TimeWindow | Window between command execution and follow-up child or file write behavior |
