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 |
|---|---|---|
| macos:unifiedlog | csrutil disable | DC0064 Command Execution |
| macos:unifiedlog | g_CiOptions modification or SIP state change | DC0063 Windows Registry Key Modification |
| macos:unifiedlog | Unsigned binary execution following SIP change | 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 |
|---|---|
PolicyPaths | Track configuration files and kernel extensions tied to SIP enforcement |
AllowedUsers | Restrict or expand which privileged accounts are monitored for SIP/CSRUTIL changes |
TimeWindow | Define correlation between csrutil execution and unsigned process activity |
