# 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 ```bash # 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/falco \ --namespace falco --create-namespace \ --set falcosidekick.enabled=true \ --set falcosidekick.webui.enabled=true \ --set driver.kind=ebpf \ --set collectors.containerd.enabled=true \ --set collectors.containerd.socket=/run/containerd/containerd.sock # Verify kubectl get pods -n f...
