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 | mprotect | 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 |
|---|---|
EntropyThreshold | Useful for tuning unpacked sections containing high entropy indicative of compression or encryption. |
TimeWindow | Can be tuned to correlate file writes to execution within a set timeframe. |
