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 | Suspicious anomalies in transmitted data integrity during application network operations | DC0078 Network Traffic Flow |
| macos:osquery | CALCULATE: Integrity validation of transmitted data via hash checks | DC0021 OS API Execution |
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 |
|---|---|
TLSValidationRules | Custom rules for enforcing HTTPS/TLS integrity checks to prevent downgrade manipulation. |
AllowedApps | Whitelisted macOS apps permitted to transmit critical data. |
