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=5136 | DC0066 Active Directory Object Modification |
| WinEventLog:Security | EventCode=4704 | DC0010 User Account Modification |
| 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 |
|---|---|
ObjectType | Focus on `trustedDomain` or `foreignSecurityPrincipal` AD objects in trust containers. |
AttributeModified | Monitor attributes like `trustPartner`, `trustDirection`, `trustType`, `msDS-TrustForestTrustInfo`. |
TimeWindow | Correlate trust creation with unusual logon events or certificate modifications. |
UserContext | Flag rare accounts or non-standard admin users performing trust changes. |
