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=4663, 4670, 4656 | DC0061 File 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 |
|---|---|
ObjectDN | Filter to specific AD containers (e.g., CN=Policies,CN=System,DC=domain,DC=com) for GPOs. |
AttributeModified | Focus on high-risk attributes such as gPCFileSysPath, ntSecurityDescriptor. |
TimeWindow | Correlate changes with suspicious process creation or privileged user logon. |
UserContext | Alert on unexpected user or service account modifying domain policy. |
