Top 10 Kubernetes Application Security Hardening Techniques

One of the main challenges developers face is how to manage security risks when deploying applications to Kubernetes clusters. A great way to address this early is by applying security hardening to the application manifests during the development process. In this post, we run down 10 ways that developers can apply hardening to their applications.

Improving Kubernetes Security: Upgrade Clusters to Avoid Exposure

With the move to cloud native development comes potentially increased risk of services that are exposed to the Internet and can easily be discovered by attackers. When combined with the fast pace of change in Kubernetes versions, there’s real risk of being one vulnerability away from a security incident. Recently I carried out some research …

Improving Your Kubernetes Authorization: Don’t Use system:masters

When you’re operating Kubernetes clusters, an important area of focus is in ensuring your authorization model is correct and provides users with the least privileges needed for them to carry out their roles. As such, blanket cluster-admin privileges should never be used and in particular the in-built system:masters group should be avoided.

Automating CIS Kubernetes Benchmark Compliance with Starboard Operator

Last year, we first released Starboard Operator, which automates vulnerability scanning and configuration auditing of Kubernetes workloads. We’re now pleased to announce the latest release (v0.10), which is focused on infrastructure and adds CIS Kubernetes Benchmark testing using kube-bench. The operator automatically discovers nodes and runs kube-bench on each node to get the benchmark score. …

Why You Shouldn’t Use Config Maps to Store Sensitive Data in K8s

One of the challenges of managing containerized environments is how to store sensitive information that’s needed for the operation of the applications running in those environments. Kubernetes provides a built-in secrets object type, but a common comment about them is that, from a technical standpoint, they’re just the same as other object types like Config …

Unveiling Aqua Vulnerability Database, Strengthen Your K8s Clusters

Published sources of vulnerabilities in cloud native environments are an important resource, but the information is often spread out across a variety of platforms. Since 80% of cloud native software is based on open source, this makes getting the most relevant and up-to-date vulnerability information a real challenge. Our new Aqua Vulnerability Database (AVD) consolidates …

Evaluating and Enforcing Least Privilege in Kubernetes with Aqua KSPM

Overly permissive defaults associated with roles and K8s subjects, such as service accounts, add risks to the attack surface of Kubernetes. And attempting to manually understand these risks and enforce least privilege rights in a Kubernetes environment is time-consuming and prone to human error. With the introduction of Kubernetes Security Posture Management (KSPM), we’ve now …

Runtime Protection for K8s Workloads Using a Mutating Admission Controller

Although Kubernetes has certainly matured into a well-adopted container orchestrator platform, it remains complex to manage and secure. Coupling this with a growing attack surface and bad actors trying to exploit it, organizations must implement a comprehensive approach to securing their K8s applications. Aqua aims to tame the complexity of securing K8s-based applications by leveraging …
