Falco vs kube-hunter
GitHub Stats
About Falco
Falco is a cloud-native runtime security tool originally created by Sysdig and now a CNCF graduated project. It monitors system calls in real-time using eBPF or a kernel module to detect abnormal behavior, intrusions, and data theft in containers, Kubernetes clusters, and Linux hosts. Falco ships with a comprehensive rule set covering the MITRE ATT&CK framework, detecting events like shell spawning in containers, unauthorized process execution, sensitive file access, network connections to suspicious destinations, and privilege escalation attempts. Rules are written in a human-readable YAML format and can be customized to match any organization's security requirements. Falco integrates with Kubernetes admission controllers to enforce security policies at deploy time, and its output can be routed to Slack, PagerDuty, SIEM systems, or any webhook endpoint for alerting.
About kube-hunter
kube-hunter is an open-source tool from Aqua Security that hunts for security weaknesses in Kubernetes clusters. It can run from outside the cluster (remote scanning), from a machine inside the network, or as a pod within the cluster itself to simulate different attacker perspectives. kube-hunter checks for a wide range of vulnerabilities including exposed API servers, kubelet API access, etcd access, privilege escalation paths, container escape vectors, and misconfigurations in RBAC, network policies, and pod security. Each finding includes a severity rating, description, and remediation guidance. The tool generates reports in JSON, YAML, or human-readable formats, making it easy to integrate into CI/CD pipelines or compliance workflows. kube-hunter is particularly valuable for security teams validating the hardening of their Kubernetes deployments.
