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 |
|---|---|---|
| auditd:SYSCALL | execve | DC0032 Process Creation |
| linux:cli | command logging | DC0064 Command 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.

|---|---|
UtilityNameList | List of binaries used for discovery (e.g., netstat, ss, lsof). |
UserContextScope | Limit detection to non-administrative or service accounts performing enumeration. |
ExecutionFrequencyThreshold | Unusual number of executions within a short time window. |
