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 | PATH | DC0040 File Deletion |
| auditd:SYSCALL | execve | DC0032 Process Creation |
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 |
|---|---|
PathRegex | Pattern matching known attacker staging directories or hidden file paths. |
TimeWindow | Deletion shortly after process execution or privilege escalation. |
SecureDeletionTool | Uncommon presence or use of `shred`, `wipe`, or `srm`. |
