Configuring Container Vulnerability Assessment (CVA)

Before you can begin assessing container images and workloads in your environment for vulnerabilities, some configuration is required within the relevant cloud service provider (CSP). For more information on what container services and registries InsightCloudSec supports, see Support.

Prerequisites

• InsightCloudSec Admin permissions (Domain or Org Admin)
• Appropriate permissions in AWS, Azure, and/or GCP:
  • For you to create roles or policies
  • For InsightCloudSec to execute container assessments (outlined in the following sections)
• Optional - Kubernetes Security Guardrails enabled if you want to have the workloads deployed into a Kubernetes cluster scanned for vulnerabilities using CVA

AWS

The permissions included in this section are required to enable container assessments within AWS environments.

You have two options for enabling CVA for AWS:

• Navigate to the IAM policy associated with InsightCloudSec and manually add the AWS CVA Permissions to it
• Attach the AWS CVA Policy to the role associated with InsightCloudSec

For instructions on configuring AWS EKS clusters, see Kubernetes Remote Scanner for EKS.

Azure

The permissions included in this section are required to enable container assessments within Azure environments.

To enable CVA for Azure:

1. Navigate to the role associated with InsightCloudSec and manually add the Azure CVA Permissions to it

For instructions on configuring AKS clusters, see Kubernetes Remote Scanner for AKS.

GCP

The permissions included in this section are required to enable container assessments within GCP environments.

To enable CVA for GCP:

1. Navigate to the service account associated with InsightCloudSec and manually add the GCP CVA Permissions to it

For instructions on configuring GKE clusters, see Kubernetes Remote Scanner for GKE.

Configuring CVA

Before container images can be regularly assessed for vulnerabilities, you must enable the feature. These configuration settings can be found on the Vulnerability Settings page, which is accessed from the Vulnerabilities page.

To enable CVA assessments:

1. Login to InsightCloudSec and navigate to the Vulnerabilities page.
2. Click Settings.
3. Navigate to the Container Assessment tab.
4. Click the Enable Container Vulnerability Assessment toggle. The list of Registries appears.

Support

The following sections outline the various container services and registries that InsightCloudSec supports for container assessment.

Cloud provider services

InsightCloudSec supports assessing images inside the following services with no additional configuration:

• Amazon Web Services (AWS), Elastic Container Service (ECS), and Elastic Kubernetes Service (EKS)
• Azure or Azure Kubernetes Service (AKS)
• Google Cloud Platform (GCP) or Google Kubernetes Engine (GKE)

Cloud provider container registries

InsightCloudSec also supports assessing images in the following registries with no additional configuration:

• AWS Elastic Container Registry (ECR)

• Azure Container Registry (ACR)
• GCP Artifact Registry or Google Container Registry (GCR)

Third party as-a-service registries

InsightCloudSec can support all third party as-a-service registries, including Private DockerHub, JFrog, Quay, and Harbor. These registries can be assessed with no authentication, username and password authentication, or API key authentication. InsightCloudSec supports the following unauthenticated third party as-a-service registries with no additional configuration:

• Alibaba Cloud
  • registry.aliyuncs.com
• Docker
  • docker.io
  • registry.hub.docker.com
  • us-docker.pkg
• GitHub
  • ghcr.io
• Google
  • gke.gcr.io
  • gcr.io
  • k8s.gcr.io
  • registry.gcr.io
  • *.gcr.iok8s-artifacts-prod
• IBM
  • icr.io
• Linkerd
  • cr.l5d.io
• Linux Server
  • lscr.io
• Kubernetes
  • registry.k8s.io
• Microsoft
  • mcr.microsoft.com
• Quay
  • quay.io
• Upbound
  • xpkg.upbound.io

Managing registries

For registries not listed in the Support section, you'll need to manually add the registry and configure authentication (if any) within InsightCloudSec. Registries can be edited, enabled, disabled, or deleted at anytime from the Action menu.

To add a registry:

1. Navigate to the Vulnerability Settings page.

2. Click + Add Registry.

3. Provide a name, base URL, and optional description for the registry.

   Base URL supports glob patterns

   The base URL supports glob patterns. For example, *.base-url.com/path/to/resource/*

4. Select if the registry is Unauthenticated or Authenticated.

5. If you selected Authenticated:

   1. Select an Authentication Type: Token or Username and Password.
      1. If you selected Token: provide the token.
      2. If you selected Username and Password: provide a username and password.
   2. Click Add Registry.

6. If you selected Unauthenticated:

   1. Click Add Registry.

The registry is enabled by default, so containers are assessed as soon as possible.

To edit a registry:

1. Navigate to the Vulnerability Settings page.
2. For a given registry, click the Action menu (...).
3. Click Edit.
4. Adjust the registry details as necessary.
5. Click Update Registry.

Troubleshooting

If you're experiencing issues harvesting and assessing images and container workloads, review the Cloud VM CVA FAQ (particularly this question) or contact support.

Using Cloud VM

Once cloud and Kubernetes onboarding & CVA configuration is complete, images will begin being harvested and assessed for vulnerabilities automatically. Cloud VM is available from the main navigation in InsightCloudSec under Security > Vulnerabilities. Review Reviewing and Managing Vulnerabilities for more information.
