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 | Execution of /usr/libexec/security_authtrampoline or child processes originating from non-trusted binaries triggering credential prompts | DC0032 Process Creation |
| macos:unifiedlog | Calls to AuthorizationExecuteWithPrivileges() observed via Apple System Logger or security_auditing tools | DC0021 OS API Execution |
| macos:unifiedlog | User credential prompt events without associated trusted installer package | DC0002 User Account Authentication |
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 |
|---|---|
BinaryReputationList | Allow list of trusted binaries invoking elevation prompts |
TimeWindow | Temporal correlation threshold between API call and credential prompt |
PromptContextValidation | Heuristic filters to determine whether a prompt context matches known legitimate installers |
