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 | Process segfault or abnormal termination after invoking vulnerable syscall sequence | DC0033 Process Termination |
| journald:Application | Segfault or crash log entry associated with specific application binary | DC0038 Application Log Content |
| NSM:Flow | Unusual request pattern leading up to service crash (e.g., malformed or oversized payload) | 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 |
|---|---|
CrashPattern | Specific binary fault signature or stack trace identifiers unique to the application context |
ExploitSourceIP | Suspect source IPs for correlation across requests and service failure timing |
