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=11 | DC0039 File Creation |
| WinEventLog:Sysmon | EventCode=1 | 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 |
|---|---|
TrustedPublisherList | Baseline list of approved certificate authorities that should not change frequently |
FilePathAllowList | Exclusions for legitimate enterprise-signed binaries stored in unusual directories |
TimeWindow | Correlation window for registry + file + process activity |
