Kubernetes Resource Scanningโ€‹

Problem: You want to secure not just your Kubernetes cluster control plane and nodes, but also the workloads you deploy to your cluster. You need visibility into the security of each of the running workloads.

Solution: Mondoo now scans each workload type as a dedicated asset, with new security and best practice policies applied to each asset. This means you'll now get not only scans of your cluster nodes and overall cluster control plane configuration, but also Pods, CronJobs, StatefulSets, DaemonSets, Jobs, and Deployments. These new assets provide more granular visibility into the workloads deployed onto your clusters and make it easy to disable or skip controls on particular workloads.

In addition to these new assets we're also shipping new Kubernetes Security and Kubernetes Best Practice policies. These new policies replace the existing Kubernetes Application Benchmark policy and apply only to the new Kubernetes resource assets. We decided to break out our combined security and best practices policy so that it would be easier to determine security vs. best practice violations at a glance. Since these policies scan individual Kubernetes assets instead of the cluster as a whole, they also feature greatly improved scan output and new remediation steps, so you can more easily resolve findings.

To enable scanning of all Kubernetes resources as individual Mondoo assets, pass the --discover all flag when scanning clusters:

mondoo scan k8s --discover all

Stay tuned for resource scanning directly in the Mondoo Kubernetes Operator and even more improvements to out-of-the-box Kubernetes policies in the coming weeks!

Google Container Operating System Support Previewโ€‹

Problem: When scanning Google Kubernetes Engine (GKE) clusters, you want to ensure the security of the cluster nodes running the Google Container OS Linux distribution.

Solution: Mondoo now includes preview support for the Google Container Operating System (GCOS). With this release, you will now see GCOS hosts properly report their release version, EOL date, and package/service states. Stay tuned for improved detection and policy support in the coming weeks.

Kubernetes k8s.initContainer Resourceโ€‹

Problem: You want to write Mondoo policies that examine the configuration of Kubernetes Init Containers in your workloads.

Solution A new k8s.initContainer allows you to write policy against Kubernetes Init Containers.

Expanded Operating System Supportโ€‹

We've updated Mondoo with enhanced platform end-of-life and package vulnerability data so you can scan the latest and greatest operating systems:

  • Added Alpine 3.16, Fedora 33/34/35, and VMware Photon 4 package vulnerability data.
  • Updated Amazon Linux 2022 vulnerability data for the latest preview release packages.
  • Added EOL date detection for openSUSE Tumbleweed and Clear Linux OS.
  • Updated EOL date detection for the new patch version format of VMware 7.x.x.

Linux Baseline Policy Improvementsโ€‹

We continue to improve our out-of-the-box Linux Baseline policy to provide better remediation steps and to support different Linux distros.

  • Skips the Ensure permissions on /etc/shadow- are configured control instead of failing when /etc/shadow- doesn't exist on the system.
  • Updates the query in the Ensure Samba is stopped and not enabled control to support Debian/Ubuntu-based Linux distros.
  • Updates the query and remediation steps for the Ensure core dumps are restricted control to support more distros.
  • Updates the query in the Ensure login and logout events are collected control to support Ubuntu.
  • Improves remediation steps and formatting throughout the policy.

Filtering in Asset Listsโ€‹

You can now quickly filter assets by their score by selecting the A-F values at the top of the fleet page.

Asset Filtering


  • Resolves failures running scans in the Kubernetes Operator.
  • VMware Mondoo appliance now includes timesyncd to prevent platform registration failures due to time drift.
  • Resolves duplicate AWS resource counts in the AWS integration pages.
  • Resolves potential failures in Mondoo Client when reporting scan results.
  • Reports all Mondoo Client scans within GitHub Actions when running the Mondoo action in multiple jobs or steps within the same workflow.
  • Resolves incorrect steps in the VMware Integration page.
  • Resolves failures in MQL when using if/else statements that have single-valued blocks.
  • Resolves the fleet summary pages sometimes showing an incorrect summary breakdown of asset scores.
