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
- Root or privileged access for driver installation
Installing Falco
Kubernetes Deployment with Helm
# Add Falco Helm chart
helm repo add falcosecurity https://falcosecurity.github.io/charts
helm repo update
# Install Falco with eBPF driver
helm install falco falcosecurity/f…
