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, fork, mmap, ptrace | DC0035 Process Access |
| auditd:SYSCALL | module load or memory map path | 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 |
|---|---|
SyscallType | Filter for fork, mmap, ptrace based on context |
ProcessName | Whitelist known daemon and scheduled task patterns |
MAPS Path | Tune suspicious memory map regions (e.g., /tmp/.evilshmem) |
