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 | process: exec + filewrite: ~/.ssh/authorized_keys | DC0032 Process Creation |
| macos:auth | ~/.ssh/authorized_keys | 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 |
|---|---|
ParentProcess | Track unusual parent process writing to SSH config (e.g., curl -> bash) |
InteractiveSessionFlag | Flag whether shell session was interactive (normal) or spawned remotely (potential abuse) |
