Detection requires visibility. Visibility requires logs. If your systems fall silent, you cannot investigate, cannot alert, cannot prove compliance. This module is about what to log, where to send it, and how to get real signal out of raw events.

The logging stack

  1. Generation — the system produces events (auth, syscalls, application logs)
  2. Collection — agents ship events from host to central pipeline
  3. Storage — long-term retention, searchable
  4. Analysis — alerts, dashboards, investigation workflows
  5. Response — action triggered on high-confidence signals
