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 | unlink, rename, open | DC0040 File Deletion |
| linux:cli | cleared or truncated .bash_history | DC0038 Application Log Content |
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 |
|---|---|
MonitoredPaths | Adjust based on syslog/auditd file paths (/var/log/messages, /var/log/audit/audit.log) |
UserContext | Scope to root/sudo usage or anomalous user behavior |
