Eyes on Runtime: Security with Falco
Learn how Falco helps detect suspicious runtime activity across containers, Kubernetes, and cloud workloads, and how tools like Sidekick, Talon, and Preempt extend that detection into alerting and automated response. This session explores how to build a practical runtime security workflow that goes from real-time detection to actionable remediation.
Unlocking Cloud-Native Threat Detection with Falco
This hands-on workshop introduces participants to real-world cloud-native threat detection using Falco, the CNCF’s open-source runtime security project. Attendees will learn how Falco monitors system, container, and Kubernetes activity to uncover anomalous or malicious behavior in real time. Through guided exercises, they will configure rules, explore alerts, and gain practical skills to strengthen runtime security in modern Kubernetes environments.
Scrap Start, Smart Finish
Subtitle: My Second-Hand Smart Home Story
