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 | write or rename to /etc/systemd/system or /etc/init.d | DC0061 File Modification |
| auditd:SYSCALL | execution of systemctl or service with enable/start/modify | 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.
| Field | Description |
|---|---|
ServicePathRegex | Path-based filters to identify service unit files or init scripts |
UserContextList | List of expected user contexts that normally perform service changes |
CommandNameList | Binaries used to register/modify services |
