Setting Up Alerting with Alertmanager

Modern DevSecOps (The Hard Way)

Don't Stare at Screens

Security is effective when you get notified when things go wrong.

Alert Logic:

  • If container_memory_usage > 90% for 5 mins -> Alert.
  • If ssh_login_failures > 10 in 1 min -> Alert.

We will configure Alertmanager to send notifications to a Slack or Discord webhook via the CLI configuration.
