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 | open | DC0055 File Access |
| auditd:SYSCALL | execve | DC0032 Process Creation |
| linux:osquery | file_events | DC0039 File 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 |
|---|---|
FileSizeThresholdMB | Defines how large a file must be to consider it padded |
UserContext | Target abnormal user behavior outside of expected automation |
TimeWindow | Time window for correlating file creation and execution |
