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 | open, rename | DC0020 Process Modification |
| linux:osquery | file_events | DC0059 File Metadata |
| EDR:detection | ThreatDetected, QuarantineLog | DC0038 Application Log Content |
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 |
|---|---|
PathWatchlist | Tunable list of directories often abused for dropped binaries (e.g., /tmp, ~/.cache, /opt/soft/). |
ProcessAncestryDepth | Limit how far up the tree to trace tool modification behavior for detection. |
