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=1 | DC0032 Process Creation |
| WinEventLog:Security | EventCode=4688 | DC0032 Process Creation |
| WinEventLog:Security | EventCode=4798, 4799 | DC0099 Group Enumeration |
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 |
|---|---|
CommandLinePattern | Match variations in enumeration commands like 'net user', 'Get-ADUser', 'dsquery'. |
TimeWindow | Short burst of account enumeration commands may indicate automation. |
UserContext | Restrict to non-admin accounts or unexpected users executing enumeration commands. |
