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 | Modifications to Mail.app plist files controlling message rules | DC0061 File Modification |
| macos:unifiedlog | Mail.app executing with parameters updating rules state | DC0032 Process Creation |
Mutable elements

| Field | Description |
|---|---|
WatchedPlistFiles | Adjust to monitor only rule-related plist files relevant to the environment. |
