[EN-C016-034] Auth Monitoring: Device-Trust Watchtower for OIDC Front Doors

Overview​

Auth monitoring is shifting from simple failed-login counters to device-trust and token-abuse visibility. Teams now treat OIDC gateways as always-on “front doors” and track anomalies before account takeover becomes visible.

Use Case​

  • Route public apps behind an OIDC reverse proxy (Authentik/Keycloak + Nginx/Caddy).
  • Correlate login events with impossible-travel, new device fingerprints, and token replay hints.
  • Trigger a responder agent that opens an evidence-first incident thread (who/when/which token/path).

Tools Used​

  • cron: continuous auth health checks and replay-signal scans
  • sessions_spawn: separate triage agent and containment agent
  • sessions_send: structured escalation with confidence score
  • message: push high-severity auth alerts to ops channels

Trend Signals (2026 Q1)​

  • r/selfhosted recently shows recurring OIDC demand for internet-exposed apps, including users asking for OIDC-ready stacks.
  • GitHub search activity around OIDC + reverse-proxy + docker-compose remains active in recent updates.
  • Operator chatter in community Discords increasingly centers on “token misuse detection” over raw failed-login counts.
