tunnel-operator

Kubernetes-native security toolkit. (Documentation)

Introduction

The Tunnel Operator leverages Trivy to continuously scan your Kubernetes cluster for security issues. The scans are summarised in security reports as Kubernetes Custom Resource Definitions, which become accessible through the Kubernetes API. The Operator does this by watching Kubernetes for state changes and automatically triggering security scans in response. For example, a vulnerability scan is initiated when a new Pod is created. This way, users can find and view the risks that relate to different resources in a Kubernetes-native way.

In-cluster Security Scans

The Tunnel Operator automatically generates and updates security reports. These reports are generated in response to new workload and other changes on a Kubernetes cluster, generating the following reports:

• Vulnerability Scans: Automated vulnerability scanning for Kubernetes workloads.
• ConfigAudit Scans: Automated configuration audits for Kubernetes resources with predefined rules or custom Open Policy Agent (OPA) policies.
• Exposed Secret Scans: Automated secret scans which find and detail the location of exposed Secrets within your cluster.
• RBAC scans: Role Based Access Control scans provide detailed information on the access rights of the different resources installed.
• K8s core component infra assessment scan Kubernetes infra core components (etcd,apiserver,scheduler,controller-manager and etc) setting and configuration.
• k8s outdated api validation - a configaudit check will validate if the resource api has been deprecated and planned for removal
• Compliance reports
  • NSA, CISA Kubernetes Hardening Guidance v1.1 cybersecurity technical report is produced.
  • CIS Kubernetes Benchmark v1.23 cybersecurity technical report is produced.
  • Kubernetes pss-baseline, Pod Security Standards
  • Kubernetes pss-restricted, Pod Security Standards
• SBOM (Software Bill of Materials genertations) for Kubernetes workloads.

Usage

The official Documentation provides detailed installation, configuration, troubleshooting, and quick start guides.

You can install the Tunnel-operator Operator with Static YAML Manifests and follow the Getting Started guide to see how vulnerability and configuration audit reports are generated automatically.

Quick Start

The Tunnel Operator can be installed easily through the Helm Chart:

Add the Aqua chart repository:

   helm repo add aqua https://khulnasoft.github.io/helm-charts/
   helm repo update

Install the Helm Chart:

   helm install tunnel-operator aqua/tunnel-operator \
     --namespace tunnel-system \
     --create-namespace \
     --version 0.18.4

This will install the Trivy Helm Chart into the tunnel-system namespace and start triggering the scans.

Status

Although we are trying to keep new releases backward compatible with previous versions, this project is still incubating, and some APIs and Custom Resource Definitions may change.

Contributing

At this early stage we would love your feedback on the overall concept of Tunnel-Operator. Over time, we'd love to see contributions integrating different security tools so that users can access security information in standard, Kubernetes-native ways.

• See Contributing for information about setting up your development environment, and the contribution workflow that we expect.
• Please ensure that you are following our Code Of Conduct during any interaction with the Aqua projects and their community.
