KubeArmor
Cloud-native security system that uses Linux security modules and eBPF to restrict pod, container, and node behavior in Kubernetes clusters.
Technical Architecture & Overview
KubeArmor is a cloud-native runtime security enforcement system for Kubernetes and virtual machines. It uses Linux security modules and eBPF to apply least-permissive policies on process execution, file access, and network operations. Administrators use it to block unwanted behavior inline and generate alerts for policy violations.
Targeted Technical Use Cases
Enforcement of runtime security policies on Kubernetes pods and virtual machines with least-permission controls.
Evaluation & Trade-offs
Core Strengths
- +Inline enforcement via Linux security modules and eBPF.
- +Native Kubernetes integration with CRD-based policy management.
- +Policy templates for common workload hardening scenarios.
Trade-Offs & Limitations
- -Enforcement depends on the Linux security modules available on the host, which vary by OS distribution.
Defensive Security Application
Prevent unauthorized process execution and file access in containerized and virtualized workloads.
