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 | None | DC0032 Process Creation |
| NSM:Firewall | pf firewall logs | DC0078 Network Traffic Flow |
| NSM:Flow | connection attempts | DC0082 Network Connection 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 |
|---|---|
TargetDomain | Identify suspicious domains often associated with CDN-routed or anonymized endpoints (e.g., Cloudflare, Fastly). |
AppleScriptUsage | Alert when AppleScript or Automator tools are used for network tunneling tasks. |
LaunchAgentSource | Monitor for LaunchAgents executing proxy tools or dynamic ports. |
