At the core of Kubernetes is the notion of high availability, meaning that every part of the system is redundant so it can continue to function despite failures. This includes multiple worker nodes to run your workload, apps are written to be able to run as multiple pods, and even the control plane will work across a cluster of machines. In this article, we’ll explain the different ways to manage network traffic in the Kubernetes cluster.

Researcher Moshe Zioni from Apiiro, discovered a major software supply chain critical vulnerability - CVE-2022-24348 - in the popular open-source CD platform Argo CD. Exploiting it enables attackers to obtain sensitive information like credentials, secrets, API keys from other applications. This in turn can lead to privilege escalation, lateral movements, and information disclosure.

Are you wondering how to secure your Kubernetes clusters? Do you even know whether your Kubernetes is secure? Kubescape by ARMO might be the tool to help you with those and many other tasks related to Kubernetes security and scanning. Check this video by Viktor Farcic from DevOps Toolkit on Kubescape as he covers the 3 main K8s security areas – While reducing the number of false positives to a minimum and getting help fixing issues.

In the last few days, Linux maintainers disclosed a broadly available Linux kernel vulnerability that enables attackers to escape containers and get full control over the node. To be able to exploit this vulnerability, the attacker needs to be able to run code in the container and the container must have CAP_SYS_ADMIN privileges. Linux kernel and all major distro maintainers have released patches.

Kubescape is now available on the Visual Studio extension marketplace. Visual Studio code extensions are add-ons that allow developers to customize and enhance their experience in Visual Studio by adding new features or integrating 3rd party tools. An extension can range in all levels of complexity, but its main purpose is to increase developers’ productivity and cater to their workflow.

For the last decade, AWS has dominated the cloud computing space with a plethora of cloud services. One of AWS’ great innovations was AWS Fargate, their first containers as a service (CaaS) offering. Prior to the introduction of Fargate, those building in the cloud were forced to choose between IaaS paradigm-focused containers or FaaS-focused serverless functions.

Five months ago, we decided to release a posture management solution for K8s and make it open source for everyone to enjoy it.

Without a doubt, Kubernetes is the most prominent container orchestration tool. And you’ve probably noticed that many positions available to IT professionals require Kubernetes experience. One way to gain or prove your Kubernetes knowledge is by becoming a Certified Kubernetes Administrator (CKA). This certification is issued by the Cloud Native Computing Foundation (CNCF) in collaboration with the Linux Foundation. They offer three Kubernetes related certifications.

On Dec 9th, a critical zero-day vulnerability - CVE-2021-44228 - was announced concerning the Java logging framework - Log4j All current versions of log4j2 up to 2.14.1 are vulnerable. To remediate this vulnerability, please update to version 2.15.0 or later.

Audit logging involves recording transactions and system events, making it an invaluable tool for regulatory compliance, digital forensics, and information security. In a typical Kubernetes ecosystem, auditing involves providing chronological, activity-relevant records documenting events and actions in a cluster. Modern logging tools come with aggregation and analytical functionalities so that teams can use log data to mitigate security threats.
