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