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 | execve | DC0032 Process Creation |
| auditd:SYSCALL | LD_PRELOAD Logging | DC0016 Module Load |
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 |
|---|---|
InjectedLibraryName | Watch for user-defined suspicious .so files (e.g., libhook.so, libshadow.so) |
TargetProcessName | Hooked binaries vary by use case (e.g., ssh, login, gdm) |
