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 call for sudo where euid != uid | DC0034 Process Metadata |
| auditd:SYSCALL | execve call for modification of /etc/sudoers or writing to /var/db/sudo | DC0061 File Modification |
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 |
|---|---|
timestamp_timeout_threshold | Tune the valid sudo session duration to reduce false positives |
command_allowlist | Filter benign sudo usage (e.g., approved admin scripts) |
