kubearmor/KubeArmor
KubeArmor
KubeArmor is a runtime security enforcement system designed to protect containerized workloads and host infrastructure by restricting unauthorized process, file, and network activity. It operates by deploying lightweight agents across nodes that utilize kernel-level interception and Linux Security Modules to monitor and block system operations in real time. By mapping these enforcement actions to specific container and pod identities, the platform maintains granular access control within multi-tenant environments.
The project distinguishes itself through a declarative policy orchestration framework that translates high-level security intent into consistent, cluster-wide rules. This architecture enables unified security management across diverse environments, including virtual machines, physical servers, and container clusters, ensuring that least-permissive configurations are applied consistently regardless of the underlying infrastructure.
Beyond core enforcement, the platform provides comprehensive observability by streaming system-level telemetry to external analysis tools. It also integrates into development workflows through command-line utilities and automated testing, allowing teams to validate workload configurations against defined safety policies before deployment. The project is distributed as a set of agents that can be provisioned across containerized or host-based environments to maintain continuous security monitoring and incident response capabilities.
Features
- Runtime Security Enforcement - Restricts process execution, file access, and network operations for containers and nodes by applying system-level security rules that block unauthorized activity in real time.
- eBPF Interceptors - Uses kernel-level hooks to monitor and intercept system calls in real time without modifying application source code.
- In-Kernel Enforcement Engines - Monitors and blocks unauthorized system calls and operations to harden workloads against potential threats.
- Security Policy Enforcers - Leverages Linux Security Modules to apply granular access control rules directly at the operating system kernel boundary.
- Declarative Policy Enforcers - Translates high-level security intent into declarative runtime rules for filesystem, network, and system call restrictions.
- DevSecOps and Automation - Integrates automated security validation into deployment pipelines to ensure workload configurations meet safety standards.
- Cloud-Native Operating Systems - Applies least-permissive security configurations to container workloads to minimize the attack surface.
- Security Agent Orchestration - Provides mechanisms to install and orchestrate security agents across containerized environments and physical servers.
- Security Testing Pipelines - Integrates automated security checks into deployment pipelines to validate workload configurations against safety policies.
- eBPF Security Tools - Uses eBPF and LSMs to restrict process, file, and network activity within containerized environments.
- Cross-Platform Security Configurations - Enforces consistent security policies across diverse infrastructure including virtual machines, physical servers, and container clusters.
- Namespace-Based Isolation - Maps system-level enforcement actions to specific container and pod identities to maintain isolation within multi-tenant environments.
- Security Orchestration - Extends runtime policy enforcement to virtual machines and physical servers through a unified control plane.
- Cloud-Optimized Linux Hardening - Implements least-permissive policies across clusters to ensure consistent access control and visibility for all active services.
- Security Enforcement Agents - Deploys lightweight enforcement daemons across every node to ensure security policies are applied locally and consistently.
- Infrastructure Observability - Monitors and streams system-level events from containers and hosts to external tools for centralized threat detection.
- System Activity Monitoring - Tracks process executions, file system accesses, and network connections to provide visibility into application activity.
- Defending - Listed in the “Defending” section of the Awesome K8s Security awesome list.

How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
