// Darktrace CEF / syslog parser — OCSF v1.3.0
|
|
//
|
|
// Supports the four canonical Darktrace log streams:
|
|
// 1. Model Breach → Detection Finding (severity from score)
|
|
// 2. AI Analyst Incident → Detection Finding (Critical)
|
|
// 3. Antigena (autonomous response) → Detection Finding (action: Blocked)
|
|
// 4. Admin / authentication events → Authentication (3002)
|
|
//
|
|
// Wire format is CEF: pipe-separated header + space-separated key=value extension.
|
|
// CEF:0|Darktrace|<product>|<ver>|<sigID>|<name>|<sev>|<extension>
