Getting Started

You can deploy Falco on a local machine, cloud, a managed Kubernetes cluster, or a Kubernetes cluster such as K3s running on IoT & Edge computing.

Falco Architecture

Falco can detect and alert on any behavior that involves making Linux system calls. Falco alerts are triggered based on specific system calls, arguments, and properties of the calling process. Falco operates at the user space and kernel space. The system calls are interpreted by the Falco kernel module. The syscalls are then analyzed using the libraries in the userspace. The events are then filtered using a rules engine where the Falco rules are configured. Suspicious events are then alerted to outputs that are configured as Syslog, files, Standard Output, and others.

Deployment

Currently, you can deploy Falco by:

• Downloading and running Falco on a Linux host or running Falco userspace program in a container, with a driver installed on the underlying host.
• Building from source and then running Falco on a Linux host or on a container.
