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 | ptrace: Processes invoking ptrace with PTRACE_TRACEME flag | 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 |
|---|---|
PtraceInvocationThreshold | Number of ptrace calls in a time window that should raise suspicion |
DevToolExclusionList | Exclude known developer tools and monitoring agents |
