Aqua Cloud Native Blog › Tags: Kubernetes Security

There are lots of security tools in the cloud native world, created by Aqua and by others, for identifying and informing users about security issues in Kubernetes environments. However powerful and useful they might be, they tend to sit alongside Kubernetes, with each new product requiring users to learn a separate set of commands and …

osquery is a SQL powered operating system instrumentation, monitoring, and analytics tool that exposes an operating system as a relational database. Using SQL, you can run queries to gain the status of your entire infrastructure. What’s cool about osquery is how easy it is to use the SQL query interface. kube-query is an open source reporting …

Yesterday more than 300 cloud native professionals assembled for KubeSec, what has now become a fixture as a “day zero” event for KubeCon/CloudNativeCon. As with previous events, the emphasis was on end-user organizations’ experiences in securing production environments. While many technical aspects and best practices were covered, this year a recurring theme was tackling the …

In this post I’ll describe how an attacker, who manages to run malicious code on a cluster can, with no special permissive permissions, successfully spoof DNS responses to all the applications running on the cluster, and from there execute a MITM (Man In The Middle) on all network traffic of pods.

Kubernetes has many moving parts, and sometimes combining them in certain ways can create unexpected security flaws. In this post you’ll see how a pod running as root and with a mount point to the node’s /var/log directory can expose the entire contents of its host filesystem to any user who has access to its …

There are major shifts happening around container technology. We have seen ongoing improvements in automation tooling and changes as fully containerized workloads move into production. Companies are often running more than one production Kubernetes cluster at a time.  DevOps and operations teams, subsequently, have an additional burden because they must control and manage these clusters, …

A new vulnerability (CVE-2019-11246) was disclosed that enables path traversal in kubectl, the popular command line interface for running commands on Kubernetes clusters. What’s interesting about this CVE is that we’ve already seen two previous variations of the same vulnerability disclosed and patched. Read on to learn how that happened.

This blog is dedicated to my Mum. She was a leading psychiatrist who loved learning and traveling. She was a huge inspiration to me. I think she would be proud that I’m pursuing my passion of traveling around the world teaching what I love. I want to start with a quote attributed to another inspiring …

Aqua recently developed a Kubernetes Operator that was successfully tested and validated by Red Hat standards for integration and supportability. Before we tell you about our new OpenShift-certified Operator, let’s get some context about what an Operator is.

Knative is the newest member of serverless environments that is gaining significant interest and generating a great deal of hype in the Kubernetes/Cloud Native community. It’s an open source framework that was designed to enable the development and deployment of container-based serverless applications that are easy to transport between cloud providers.

When you’re running Kubernetes, how do you know whether it’s configured securely? Kubernetes is a complex system, with several control plane components, each of which has numerous configuration parameters. In some cases, it’s clear that a parameter will have an impact on Kubernetes security – for example, providing keys and certificates for setting up secure …

In this series of blog posts we had an introduction to Istio, and an overview of its security features. This post completes the series with a look at how we can leverage Istio’s traffic control features to provide increased observability and control over the operation and deployment of our applications.
