Falco is a CNCF graduated cloud-native runtime security project that serves as the de facto standard for Kubernetes runtime security by monitoring system calls and alerting on violations of security rules 0:00-0:32.
Key Takeaways:
• Falco works by intercepting system calls between applications and the kernel using drivers in kernel space and an engine in user space, enriching data, checking against rules, and alerting on violations 0:56-2:07
• Creating custom Falco rules involves writing conditions with supported fields (like FD.name and evt.type) to detect specific behavior, then applying through config maps and DaemonSets 4:25-8:30
• Falco can be installed directly on nodes or as a Kubernetes DaemonSet, with rules stored in configuration files like falco_rules.yaml 11:45-14:42
• Rule outputs can be customized to include specific information like timestamps and container IDs for enhanced security monitoring 16:32-20:10
Understanding Falco is essential for Kubernetes security and preparation for the Certified Kubernetes Security Specialist (CKS) exam 0:38-0:51.

Kubernetes security is not a new topic and whenever we talk about securing Kubernetes cluster there is a thing called runtime Kubernetes security and in that there is a particular project called Falco which we'll be discussing in this particular video. So Falco is a cloudnative runtime security project. It is CNCF graduated project and it started out in 2016 was donated to CNCF in 2018 and now it's a CNCF graduated project and it's kind of the de facto standard for the Kubernetes runtime security. So let's try to understand what it means first and then we'll move on to how and why it is important from CKS point of view which is certified cubernetes speciality exam and what type of scenarios can we [Music] expect. So whenever there is a application application talks to the kernel and applic…
