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 | dscl . -create | DC0064 Command Execution |
| macos:unifiedlog | modification to /var/db/dslocal/nodes/Default/users/ | 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 |
|---|---|
UsernamePattern | Attackers may use service-like names to hide malicious accounts |
ExecutionSource | Accounts created via Terminal vs GUI vs remote session can affect confidence |
