This is the fifth and final part of Vincent Danen’s “Patch management needs a revolution” series.Patch management needs a revolution, part 1: Surveying cybersecurity’s lineagePatch management needs a revolution, part 2: The flood of vulnerabilitiesPatch management needs a revolution, part 3: Vulnerability scores and the concept of trustPatch management needs a revolution, part 4: Sane patching is safe patching is selective patchingThere is an intersection between “compliance” and “security” but it’s wise to realize that compliance does not equal security. Compliance, when don

The trusted platform module (TPM) is a self-contained hardware encryption technology present in recent computer systems. It provides, among other things, hardware random number generation and more secure storage for encryption keys. This enables administrators to encrypt operating system disks that will then only be decryptable on the same system. Version 2.0 of the TPM specification was published in 2015, and Microsoft’s Windows 11 requires a version 2.0 TPM to be present to install.To support operating systems like Windows 11 that require a TPM, libvirt provides a virtual TPM (vTPM) that c

Red Hat has always been an advocate of growth at the intersection of open source and computing solutions–which is exactly where RISC-V can be found. RISC-V is one of those technologies where the future is both evident and inevitable. By integrating open source concepts with the hardware development process, it’s not hyperbole to say that RISC-V is disrupting the hardware industry.Our excitement around the unique value RISC-V brings to the hardware ecosystem as an open and collaborative instruction set architecture (ISA) is nothing new. Red Hat has been providing Fedora on RISC-V for severa

When it comes to open-source innovation, Red Hat is committed to pushing technological boundaries and enhancing the capabilities of cutting-edge solutions. As we look back at 2023, we’ll discuss Red Hat's role in advancing Extended Berkeley Packet Filter (eBPF) technology, from collaborative contributions to the Linux kernel to strategic implementations within Red Hat's portfolio, and explore the intersection of innovation, performance, security capabilities and networking within the evolving landscape of eBPF.Kernel upstream collaborationsRed Hat engineers actively collaborated with the Lin

Peer-pods extends Red Hat OpenShift sandboxed containers to run on any environment without requiring bare-metal servers or nested virtualization support. It does this by extending Kata containers runtime (OpenShift sandboxed containers is built on Kata containers) to handle virtual machine (VM) lifecycle management using cloud provider APIs (AWS, Azure and others) or a third-party hypervisor API such as VMware vSphere. The peer-pods solution is also the foundation for confidential containers on OpenShift.Currently, there is no support for Container Storage Interface (CSI) persistent volumes fo

Recently, Red Hat announced the technical preview of Red Hat Trusted Artifact Signer which is a production-ready deployment of the Sigstore project for enterprise use. In this article, we will learn how to use Trusted Artifact Signer when signing, attesting and verifying a container image with cosign and Enterprise Contract (EC).Before starting, we must deploy Trusted Artifact Signer on our Red Hat OpenShift cluster by following Chapter 1 of the Deployment Guide. Be sure to also run the source ./tas-env-variables.sh script to set up the shell variables (URLs) to the Sigstore services endpoint

This is the fourth part of Vincent Danen’s “Patch management needs a revolution” series.Patch management needs a revolution, part 1: Surveying cybersecurity’s lineagePatch management needs a revolution, part 2: The flood of vulnerabilitiesPatch management needs a revolution, part 3: Vulnerability scores and the concept of trustOne of the biggest concerns with modern patch management is that we haven’t truly challenged our thinking around “patching everything” over the past 40 years. Today, we are still inundated with customer requests to patch everything, despite the available ev

Red Hat Satellite provides webhooks to notify or perform an action when an event occurs. For example, webhooks can inform you of the completion of errata installation on Red Hat Enterprise Linux (RHEL) hosts (amongst many other events). The webhook mechanism helps integrate Satellite with applications such as Red Hat Ansible Automation Platform, Splunk and ServiceNow, to name a few.What is a webhook?In general, a webhook is an API call (or programmatic procedure/function) using the HTTP protocol. In Satellite, specific events can trigger the running of webhooks. Particular events can include c

In 2023, Red Hat met with so many customers and partners – from industry event interactions and individual meeting rooms to cross country visits and late-night service calls, we’ve learned so much from our trusted ecosystem. With all of these lasting connections made, along with so many new projects launched, we can’t wait to see what this year will bring. As we look ahead to the rest of 2024 and gather together again soon at MWC Barcelona, I wanted to take some time to reflect on what we’ve learned to set our customers and partners up for success in 2024.What’s top of mind for servi

Red Hat OpenShift sandboxed containers (OSC) version 1.5.0, introduces Peer Pods to IBM Z and LinuxONE. This update is the product of a cooperation between IBM and Red Hat, and is an important step in improving sandboxed containers, paving the way for Confidential Containers. By integrating with IBM Z and LinuxONE, OpenShift sandboxed containers help tackle the challenges of providing more secure and efficient containerized applications in complex IT infrastructures.Understanding Peer Pods in OpenShiftPeer Pods have expanded the capabilities of OpenShift, allowing for the use of Kata Container
