Kubescape

Comprehensive Kubernetes Security from Development to Runtime

Kubescape is an open-source Kubernetes security platform that provides comprehensive security coverage from left to right across the entire development and deployment lifecycle. It offers hardening, posture management, and runtime security capabilities to ensure robust protection for Kubernetes environments.

Key features of Kubescape include

• Shift-left security: Kubescape enables developers to scan for misconfigurations as early as the manifest file submission stage, promoting a proactive approach to security.
• IDE and CI/CD integration: The tool integrates seamlessly with popular IDEs like VSCode and Lens, as well as CI/CD platforms such as GitHub and GitLab, allowing for security checks throughout the development process.
• Cluster scanning: Kubescape can scan active Kubernetes clusters for vulnerabilities, misconfigurations, and security issues
• Multiple framework support: Kubescape can test against various security frameworks, including NSA, MITRE, SOC2, and more.
• YAML and Helm chart validation: The tool checks YAML files and Helm charts for correct configuration according to the frameworks above, without requiring an active cluster.
• Kubernetes hardening: Kubescape ensures proactive identification and rapid remediation of misconfigurations and vulnerabilities through manual, recurring, or event-triggered scans.
• Runtime security: Kubescape extends its protection to the runtime environment, providing continuous monitoring and threat detection for deployed applications.
• Compliance management: The tool aids in maintaining compliance with recognized frameworks and standards, simplifying the process of meeting regulatory requirements.
• Multi-cloud support: Kubescape offers frictionless security across various cloud providers and Kubernetes distributions.

By providing this comprehensive security coverage from development to production, Kubescape enables organizations to implement a robust security posture throughout their Kubernetes deployment, addressing potential vulnerabilities and threats at every stage of the application lifecycle.

Kubescape was created by ARMO and is a Cloud Native Computing Foundation (CNCF) sandbox project.

Demo

Kubescape has a command line tool that you can use to quickly get a report on the security posture of a Kubernetes cluster:

Getting started

Experimenting with Kubescape is as easy as:

curl -s https://raw.githubusercontent.com/kubescape/kubescape/master/install.sh | /bin/bash

This script will automatically download the latest Kubescape CLI release and scan the Kubernetes cluster in your current kubectl context.

Learn more about:

• Installing the Kubescape CLI
• Running your first scan
• Accepting risk with exceptions

Did you know you can use Kubescape in all these places?

Continuous security monitoring with the Kubescape Operator

As well as a CLI, Kubescape provides an in-cluster mode, which is installed via a Helm chart. Kubescape in-cluster provides extensive features such as continuous scanning, image vulnerability scanning, runtime analysis, network policy generation, and more. Learn more about the Kubescape operator.

Using Kubescape as a GitHub Action

Kubescape can be used as a GitHub Action. This is a great way to integrate Kubescape into your CI/CD pipeline. You can find the Kubescape GitHub Action in the GitHub Action marketplace.

Under the hood

Kubescape uses Open Policy Agent to verify Kubernetes objects against a library of posture controls. Kubescape retrieves Kubernetes resources from the API server and runs a set of Rego snippets developed by ARMO.

Container image scanning is powered by Grype and image patching uses Copacetic.

By default, CLI scan results are printed in a console-friendly manner, but they can be:

• exported to JSON, junit XML or SARIF
• rendered to HTML or PDF
• submitted to a cloud service
