KubeArmor
Cloud-native Runtime Security Enforcement System.
Overview
KubeArmor is a cloud-native runtime security engine that restricts the behavior of pods, containers, and nodes at the system level. It uses Linux Security Modules (LSMs) like AppArmor, SELinux, and BPF-LSM to enforce policies, preventing actions like specific process executions, file access, and network operations. This allows for workload hardening and sandboxing.
✨ Key Features
- Runtime security enforcement
- Uses Linux Security Modules (AppArmor, SELinux, BPF-LSM)
- Policy-based controls for processes, files, and networking
- Workload hardening and sandboxing
- Rich telemetry and alerting using eBPF
- CNCF Sandbox Project
🎯 Key Differentiators
- Kubernetes-native policy language.
- Simplifies the use of underlying LSMs.
- Combines policy enforcement with rich, container-aware telemetry.
Unique Value: Provides a simple yet powerful way to enforce runtime security by restricting the behavior of applications at the OS level, directly from Kubernetes.
🎯 Use Cases (4)
✅ Best For
- Restricting process execution within containers to prevent malicious activity
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Pre-deployment configuration checking (it's a runtime tool)
- Network policy enforcement at L4/L7 (focus is on host-level restrictions)
🏆 Alternatives
Unlike detection-focused tools like Falco, KubeArmor is designed to proactively block malicious activities based on predefined policies.
