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=4657 | DC0063 Windows Registry Key Modification |
| WinEventLog:Sysmon | EventCode=10 | DC0035 Process Access |
| WinEventLog:Sysmon | EventCode=7 | DC0016 Module Load |
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 |
|---|---|
MonitoredRegistryKeys | Specific LSASS and password filter registry paths monitored for modification. |
TimeWindow | Correlation window between registry change, DLL load, and lsass.exe access. |
