  5. 5. Getting Started
  6. 6. Getting Started Resources Security Onion - Infrastructure Security Appliance Docker - Containers great for testing security tooling
  7. 7. SIEM
  8. 8. Security Information and Event Management Aggregates incoming information from network sensors Single pane of glass for current network state Alerts analysts of current incidents and needs
  9. 9. SIEM - Events vs. Incidents Events - Real things that happened Incidents - Security “problems”
  10. 10. SIEM - Goal Alert analysts of incidents and give them the ability to correlate them to events

  22. 22. Performance Looking for anomalies in performance data Solutions: Visualization: Grafana Storage: InfluxDB, Graphite Collection: Prometheus, Telegraf
  23. 23. State Looking for anomalies in current server state Solutions: OS query + Fleet Puppet + PuppetDB
