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=5145 | DC0102 Network Share Access |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File 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 |
|---|---|
ShareName | Organizations may use custom share paths outside of default C$, Admin$, etc. |
ProcessName | Common toolsets vary; defenders should tailor to unusual processes for their environment. |
TimeWindow | Time of day and access duration may need to be tuned to reduce false positives. |
