Falco for Kubernetes runtime security (eBPF, Rules, Tuning & Alerts)

Dec 2, 2025

Runtime attacks don’t wait for your next scan. Falco detects suspicious behavior in real time across Kubernetes, containers, and Linux hosts—using syscall signals (eBPF/kernel module) plus a rule engine and plugins.

In ~10 minutes, you’ll learn how Falco works end-to-end, where it fits in a modern cloud-native security stack, and how to operationalize it without drowning in noise.

In this video:

  • What Falco is (and what it’s not): runtime behavioral detection vs. static scanning
  • How Falco works: event capture → enrichment → rules → alerts
  • Drivers: modern eBPF probe vs kernel module (tradeoffs + compatibility)
  • What Falco can catch: shells in containers, writes to /etc, privilege escalation patterns, unexpected outbound connections
  • Plugins & ecosystem: Kubernetes audit logs, cloud events, custom sources
  • Practical rollout: start small, tune rules, route alerts to your workflow (Slack/SIEM/PagerDuty), measure overhead

Getting started checklist (practical):

  • Install Falco (Kubernetes via Helm or on hosts)
  • Start with default rules
  • Forward outputs to where engineers live (Slack/SIEM/alerts)
  • Tune noisy rules + baseline “normal” behavior
  • Expand with plugins + map to incident workflows (MITRE/NIST)
