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:EXECVE | systemctl stop auditd, kill -9 <pid>, or modifications to /etc/selinux/config | DC0032 Process Creation |
| auditd:SYSCALL | kill syscalls targeting logging/security processes | DC0033 Process Termination |
| linux:syslog | iptables or nftables rule changes | DC0051 Firewall Rule 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 |
|---|---|
ServiceList | Adjust monitored security service names depending on host configuration. |
TimeWindow | Correlate multiple kill/stop events in short succession. |
