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:Sysmon | EventCode=11 | DC0039 File Creation |
| WinEventLog:Security | EventCode=4688 | DC0032 Process Creation |
| WinEventLog:Sysmon | EventCode=3, 22 | DC0082 Network Connection Creation |
| WinEventLog:Sysmon | EventCode=13, 14 | DC0063 Windows Registry Key Modification |
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 |
|---|---|
UserContext | Extension installation by privileged or domain users may require higher scrutiny |
BrowserExecutablePath | Custom or portable browsers may not match default paths |
ExtensionInstallPath | Installation paths may vary by version or user profile |
