Detecting Container Escape with Falco Rules

Overview

Falco is a CNCF-graduated runtime security tool that monitors Linux syscalls to detect anomalous container behavior. It uses a rules engine to identify container escape techniques such as mounting host filesystems, accessing sensitive host paths, loading kernel modules, and exploiting privileged container capabilities.

When to Use

• When investigating security incidents that require detecting container escape with falco rules
• When building detection rules or threat hunting queries for this domain
• When SOC analysts need structured procedures for this analysis type
• When validating security monitoring coverage for related attack techniques

Prerequisites

• Linux host with kernel 5.8+ (for eBPF driver) or kernel module support
• Kubernetes cluster (v1.24+) or standalone Docker/containerd
• Helm 3 for Kubernetes deployment
