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 |
|---|---|---|
| WinEventLog:Sysmon | EventCode=3, 22 | DC0082 Network Connection Creation |
| WinEventLog:Sysmon | EventCode=1 | DC0032 Process Creation |
| WinEventLog:Security | EventCode=4663, 4670, 4656 | DC0055 File Access |
| NSM:Flow | ssl.log - Certificate Analysis | DC0085 Network Traffic 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 |
|---|---|
TimeWindow | Correlates file access, encryption, and network transmission within a timeframe (e.g., 5 minutes). |
CertificateIssuerDenylist | Blocks or flags untrusted certificate authorities in SSL/TLS handshakes. |
BinaryAllowlist | Whitelist for known-good applications allowed to use encrypted outbound traffic. |
