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 | ptrace, mmap, process_vm_writev | DC0021 OS API Execution |
| auditd:SYSCALL | open | DC0055 File Access |
| linux:procfs | /proc/[pid]/maps, /proc/[pid]/mem | DC0020 Process 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 |
|---|---|
TargetPIDThreshold | Limit to sensitive or unexpected processes being targeted (e.g., sshd, init) |
TimeWindow | Correlate mmap or writev usage to process access within a short timeframe |
