KubeArmor

KubeArmor is an open-source, CNCF Sandbox–hosted runtime Kubernetes security enforcement engine designed for cloud-native workloads. It leverages eBPF and Linux Security Modules (LSMs)—like AppArmor, SELinux, and BPF-LSM—to proactively harden workloads, sandboxing them against security threats by enforcing user-defined policies at runtime.

Key Features

• Inline Mitigation: Preemptively hardens pods, containers, and virtual machines without modifying workloads or host configurations.
• Behavior Restriction: Controls process executions, file access, networking operations, and resource usage within workloads.
• Policy Enforcement & Logging: Enforces policies based on container or workload identity and logs violations with rich telemetry via eBPF.
• Kubernetes-Native: Simplifies using LSMs by abstracting complexity and enabling policy creation through Kubernetes metadata.
• Compliance & Hardening Templates: Offers policies based on MITRE, CIS, NIST, and STIG frameworks for infrastructure hardening.
• Wide Adoption: Trusted by a broad community with over 1.2 million+ downloads, demonstrating reliability and maturity.

This redesign emphasizes security-first UX, clearer policy understanding, and documentation that aligns visuals and functionality with KubeArmor’s powerful runtime enforcement features—bringing clarity and confidence to users from developers to security engineers.
