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 | httpd spawning bash, zsh, python, or osascript | DC0032 Process Creation |
| auditd:SYSCALL | file write operations in /Library/WebServer/Documents | DC0061 File Modification |
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 |
|---|---|
InterpreterName | Adversary may use different scripting environments |
ExecutionParent | Not all web servers are named httpd; may differ in custom deployments |
