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=4720 | DC0014 User Account Creation |
| windows:osquery | User enumeration with creation/last modified timestamps | DC0013 User Account Metadata |
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 |
|---|---|
SimilarityThreshold | Defines how close in Levenshtein or visual distance an account name must be to a legitimate one to raise an alert. |
MonitoredAccountList | Set of known legitimate accounts to compare new account names against. |
TimeWindow | Period within which anomalous account creation or renaming is evaluated in relation to discovery or deletion activity. |
