What Gartner Wants Every CTO to Know About Kubernetes Security

In the new Gartner Top 10 FAQs for CTOs on container and Kubernetes infrastructure report, there’s a strategic planning assumption that “by 2029, more than 95% of global organizations will be running containerized applications in production, which is a significant increase from less than 50% in 2023.” So is that it? Will container and Kubernetes …

On March 24, 2025, a set of critical vulnerabilities (CVE-2025-1097, CVE-2025-1098, CVE-2025-24514, and CVE-2025-1974 — collectively referred to as IngressNightmare was disclosed in the ingress-nginx Controller for Kubernetes. These vulnerabilities could lead to a complete cluster takeover by granting attackers unauthorized access to all secrets stored across all namespaces in the Kubernetes cluster.

Implementing Kubernetes securely can be a daunting task. Fortunately, there are tools in the K8s toolshed that provide out-of-the-box solutions using a single click. One such tools is OPA Gatekeeper. It is a great out-of-the-box security checkpoint to enforce security policies on Kubernetes. But are users using it correctly? Do they understand its limitations? Our …

Did you know that Kubernetes originally had no built-in features for managing user permissions, or that support for storing data persistently didn’t appear until Kubernetes was four years old?

Amazon Elastic Kubernetes Service (Amazon EKS) streamlines the process of deploying, managing, and scaling Kubernetes clusters on Amazon Web Services (AWS), sparing users the complexities of setting up and maintaining their own Kubernetes control plane. Kubernetes itself is an open-source platform designed to automate the management, scaling, and deployment of applications within containers.   

If you deploy applications using Kubernetes – a platform that 96 percent of companies today report either using or considering – you’ll inevitably need to manage secrets securely inside Kubernetes. In some ways, this is a challenging task. Although Kubernetes provides some built-in capabilities to help manage secrets securely, these features have their limitations – …

Exposed Kubernetes secrets pose a critical threat of supply chain attack. Aqua Nautilus researchers found that the exposed Kubernetes secrets of hundreds of organizations and open-source projects allow access to sensitive environments in the Software Development Life Cycle (SDLC) and open a severe supply chain attack threat. Among the companies were SAP’s Artifacts management system …

Early this summer we announced the release of Kubernetes Bills of Material (KBOM) as part of Trivy, our all in one, popular open source security scanner. In the blog we discussed how KBOM is the manifest of all the important components that make up your Kubernetes cluster: Control plane components, Node Components, and Addons, including …

If you thought that falling victim to ransomware, or a hacker hijacking your workstation was a nightmare, consider the potential catastrophe of having your Kubernetes (k8s) cluster hijacked. It could be a disaster magnified a million times over.

SBOM (Software Bill of Materials) is an accepted best practice to map the components and dependencies of your applications in order to better understand your applications’ risks. SBOMs are used as a basis for vulnerability assessment, licensing compliance, and more. There are plenty of available tools, such as Aqua Trivy, that help you easily generate …

We have recently discovered the first-ever evidence that attackers are exploiting Kubernetes (K8s) Role-Based Access Control (RBAC) in the wild to create backdoors. The attackers also deployed DaemonSets to take over and hijack resources of the K8s clusters they attack. Our research suggests that this campaign is actively targeting at least 60 clusters in the …

One of Trivy’s core features is Trivy Kubernetes for in-cluster security scans of running workloads. This tutorial will showcase how to generate CIS and NSA reports both through the Trivy CLI and the Trivy Operator. Additionally, we will look at how users can add the Kubernetes Specification for their own Compliance Report format to expand …
