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 | access to keychain database | DC0055 File Access |
| macos:unifiedlog | execution of security or osascript | 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 |
|---|---|
AllowedApplications | Whitelist of legitimate processes accessing the Keychain |
AlertThreshold | Number of failed access attempts before raising an alert |
