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 | dns-sd, mDNSResponder, socket activity | DC0085 Network Traffic Content |
| macos:osquery | process_events | 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 |
|---|---|
MDNSServiceQueryPatterns | mDNS queries such as _ssh._tcp.local that may indicate service discovery. |
UserContext | Adjust alerting based on whether discovery activity originates from a background daemon vs. interactive session. |
ScanToolList | Expected tools that could trigger mDNS or TCP/UDP scans (e.g., dns-sd, nmap). |
