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 |
|---|---|---|
| linux:syslog | kernel|systemd messages indicating 'segmentation fault'|'core dumped'|'service terminated unexpectedly' for sshd, smbd, vsftpd, mysqld, httpd, etc. | DC0038 Application Log Content |
| auditd:SYSCALL | execve of /bin/sh,/bin/bash,/usr/bin/curl,/usr/bin/python by service accounts (e.g., apache, mysql, nobody) immediately after inbound network activity. | DC0032 Process Creation |
| NSM:Flow | Inbound connections to monitored service ports from external or unusual internal sources; rapid follow-on lateral connections from the same host. | DC0085 Network Traffic 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 |
|---|---|
ServiceNames | Linux daemons to watch (sshd, smbd, nfsd, httpd/nginx, mysqld, postgres, redis). |
CoreDumpPaths | Paths indicating crash artifacts (/var/crash, /var/lib/systemd/coredump). |
ShellSpawnAllowlist | Paths/users allowed to spawn shells from services (default: empty). |
TimeWindow | Correlation window (default 10m). |
