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 | useradd or adduser executed | DC0014 User Account Creation |
| auditd:SYSCALL | chmod/chown to /etc/passwd or /etc/shadow | 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 |
|---|---|
BinaryPath | Custom scripts or renamed binaries may evade simple path-based detection |
ExecutionTime | Account creation outside maintenance windows may indicate compromise |
