Maintaining compliance to cybersecurity standards can be a daunting task, but you can mitigate that by using Red Hat Insights. With the latest feature update, the Red Hat Insights Compliance reporting service now allows you to edit the rules in your policies to meet your organization's requirements, giving you visibility and control over your servers. Red Hat Insights is a managed service, included with every Red Hat Enterprise Linux (RHEL) subscription, that continuously analyzes platforms and applications to help you manage your hybrid cloud environment. Red Hat Insights uses predictive a

There’s a movement going on in the world of Department of Defense (DoD) applications. The momentum surrounding application modernization efforts means containerized applications show growth in the DoD. That, combined with task orders coming out using the Joint Warfighting Cloud Capability (JWCC) contract, leads to the question, “How do we increase the security of containerized applications in this new landscape?” Traditional ACAS (Assured Compliance Assessment Solution) scans don’t really work in a containerized environment. You can certainly scan containerized applications, but in

Red Hat strives to get better at what we do, faster at how we do it, while maintaining high quality results. In modern software development, that means focusing on security as early as possible into our software development process, and continuously driving improvements by listening and acting upon early feedback in the Secure Development Lifecycle (SDL). One important tool toward that goal is the Common Weakness Enumeration (CWE), a community-developed taxonomy of flaws. We use CWE classifications to gather intelligence and data to visualize clustering common weaknesses. We can then better

As the IT security landscape continues to evolve, so do the practices that IT organizations use to mitigate threats and maintain a more secure operating environment. Staying ahead of attackers and minimizing the cost of defense requires constant and appropriate reflection and analysis to improve processes and strategies. In this series, we explain what a CWE is, share our background on CWE collection, and explain how Red Hat has evolved our usage of CWEs over the past few years. What is a CWE? Common Weakness Enumeration (CWE) is a community-developed taxonomy of weaknesses maintained by

Based on Kata Containers, the Confidential Containers (CoCo) project is a community solution to enable hardware technologies for virtualized memory encryption in container environments through attestation. CoCo SEV enables an encrypted container launch feature by utilizing a remote key broker service to verify the guest measured environment before releasing the image decryption key during orchestration. This blog demonstrates how to prepare an EPYC™ CPU-powered machine for SEV and CoCo, how to install CoCo using a Kubernetes operator, and how to create an encrypted image and start a containe

I imagine I am not the only systems administrator who struggled with driving security compliance across a disparate fleet of Linux systems. It took up hours of administrative time and often required interaction with a third-party auditor to validate the results. Let’s talk about the multiplication here: You may have a batch of systems that handle payment processing, so they are required to comply with the rules for PCI-DSS. You may have another set of systems that handle your patient’s medical records, which would fall under the purview of HIPAA. Many of these certifications require com

As the world's leading provider of enterprise-ready open source software, Red Hat is uniquely positioned to help prepare the widely varying users of its embedded platform cryptography for the transition to a post-quantum world. In fact, the US Government calls it "imperative" in a recent National Security Memorandum: [Becoming quantum-ready is] imperative across all sectors of the United States economy, from government to critical infrastructure, commercial services to cloud providers, and everywhere else that vulnerable public-key cryptography is used — NSM-10 Part of Red Hat's

Peer-pods is a new Red Hat OpenShift feature that enables an OpenShift sandboxed container (OSC) running on a bare-metal deployment to run on OpenShift in a public cloud and on VMware. It's not uncommon to want to run OpenShift in a virtual machine instead of on the bare-metal nodes. While it's possible to run a virtual machine inside a virtual machine, it demands a whole new subset of support concerns when you do it in production. In this article, I'll demonstrate how to solve this problem, using a combination of peer-pods and libvirt. By the end of this tutorial, you'll know how to create a

This article is the last in a six-part series (see my previous blog) presenting various usage models for Confidential Computing, a set of technologies designed to protect data in use. In this article, I explore interesting support technologies under active development in the confidential computing community. Kernel, hypervisor and firmware support Confidential Computing requires support from the host and guest kernel, the hypervisor, and firmware. At the time of writing, that support is uneven between platforms. Hardware vendors tend to develop and submit relatively large patch series, w

The Red Hat Enterprise Linux 9.2 CVM Preview image for Azure confidential VMs has been released, and it represents an important step forward in confidential virtual machines. In this article, I focus on the changes Implemented to support the emerging confidential computing use-case, and some of the expected changes in the future. For this article, I'm using confidential virtual machines (CVMs) with the Technology Preview of Red Hat Enterprise Linux 9.2, running as a guest on Microsoft Azure confidential VMs. This builds on my previous post in which I discussed the high-level requirements fo
