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 | connect | DC0082 Network Connection Creation |
| NSM:Flow | http.log, ftp.log | DC0085 Network Traffic Content |
| NSM:Flow | flow records | DC0078 Network Traffic Flow |
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 |
|---|---|
SensitiveDirectoryWatchlist | Flag access to paths known to store sensitive or regulated data. |
ProcessBaseline | Define which binaries are allowed to communicate externally using HTTP/FTP. |
TimeWindow | Correlates process/file/network within a defined time window. |
