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 |
| auditd:SYSCALL | PATH | DC0040 File Deletion |
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 |
|---|---|
TimeWindow | The time window used to correlate log file interaction and suspicious command execution. |
LogFilePathPattern | Regex pattern used to match monitored log file paths (e.g., /var/log/auth.log). |
UserContext | User or group (e.g., root) that should trigger higher severity detection. |
