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 | connect | DC0082 Network Connection Creation |
| NSM:Flow | ssl.log, conn.log | DC0085 Network Traffic Content |
| auditd:SYSCALL | open, read | DC0055 File Access |
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 |
|---|---|
ConnectionDestinationScope | Restrict outbound connections to non-corporate domains or IPs. |
FileAccessExtensionList | List of extensions considered sensitive or exfil-worthy (e.g., .zip, .db, .xlsx). |
SSLClientProcessBaseline | Define normal encrypted-traffic-capable binaries. |
