Today we're excited to announce a new mechanism for admins to safely and easily customize an operating system deployment with highly refined needs while taking full advantage of the automation and power provided by Red Hat OpenShift. This means you don't have to second guess the need for special device drivers for uncommon hardware, system agents, or organizational demands that require more control over your host operating system.Red Hat OpenShift is designed to run on a wide variety of hardware and operational contexts. OpenShift runs so well in a variety of environments that admins rarely ne

The Marvin Attack is a new side-channel attack on cryptographic implementations of RSA in which the attacker decrypts previously captured ciphertext by measuring, over a network, server response times to specially crafted messages. The attacker also may forge signatures with the same key as the one used for decryption. Red Hat published the principles and technical background of the Marvin Attack in September of 2023.Since that time, we have identified lots of other vulnerable implementations and have shipped fixes. Note that most of the CVEs in applications that use OpenSSL have only received

In a previous Red Hat article, VP of Red Hat Product Security, Vincent Danen, discussed the question "Do all vulnerabilities really matter?" He emphasized that "a software vulnerability has the potential to be exploited by miscreants to harm its user." The key word here is "potential". If the potential for exploitation is high, or if an exploit for a vulnerability is already in use in the wild, then these vulnerabilities pose a greater risk and must be prioritized and addressed promptly.Red Hat uses CISA as a source for known exploited vulnerabilitiesThe Cybersecurity and Infrastructure Secur

It is hard to imagine any modern computer system that hasn't been improved by the power of artificial intelligence (AI). For example, when you take a picture with your smartphone camera, on average more than twenty deep learning (DL) models spring into action, ranging from object detection to depth perception, all working in unison to help you take that perfect picture!Business processes, productivity applications and user experiences can all be enhanced by using some form of AI, and few other technologies have grown with the same size, speed and reach. Like any other piece of technology, howe

Testing environmentIn this performance analysis, we investigate various configurations and testing scenarios to showcase IPsec throughput on the latest RHEL 9 platform. Our choice of a modern multicore CPU and the latest stable RHEL aims to represent today's technological capabilities.Hardware configurationDual socket of 28 cores each Intel 4th Generation Xeon Scalable ProcessorHyper-threading enabled (two sockets with 56 logical cores each)Directly connected high-speed 100Gbit Intel E810 network cardsSoftware informationDistribution: RHEL-9.4.0Kernel: 5.14.0-427.13.1.el9_4.x86_64NetworkManage

In the last few years, several Red Hat customers have asked how to add a Web Application Firewall (WAF) to the OpenShift ingress to protect all externally facing applications.A WAF is a Layer 7 capability that protects applications against some types of web-based attacks, including but not limited to Cross Site Request Forgery (CRSF), Cross-Site Scripting (XSS) and SQL injection (for a more comprehensive list of all known web based attacks, see here).Unfortunately, OpenShift does not have these capabilities included within the default ingress router, and as a result, alternate solutions must

ANSSI, the National Cybersecurity Agency of France (Agence nationale de la sécurité des systèmes d'information), provides a configuration guide for GNU/Linux systems. It's identified as ANSSI-BP-028 (formerly known as ANSSI DAT NT-028). Recently, ANSSI published an update of its ANSSI-BP-028 configuration recommendations. In this post, I review what has changed from version 1.2 to 2.0, and what it might mean for you as a Red Hat Enterprise Linux (RHEL) user. Most importantly, I also illustrate how to verify compliance of your systems with this updated Security Content Automation Protocol (S

A lot of organizations use Red Hat Ansible Automation Platform to orchestrate their infrastructure and Hashicorp Vault to manage their secrets. But how do they work together?HashiCorp Vault is a powerful tool for managing secrets, providing a centralized platform for storing, accessing, and distributing sensitive information. When combined with Ansible Automation Platform, you can streamline and automate secret management across your infrastructure. In this blog post, we'll explore how to integrate HashiCorp Vault with Ansible Tower to automate secret management effectively.Workflow outlineThe

The concept of security by design, which includes the concept of security by default, is not new. In fact, secure by design is considered one of the fundamental principles of secure development. In general, we say there is security by design or security by default when, from the user's point of view, security is included and enabled without doing anything specific or changing the factory configurations. The Cybersecurity Infrastructure Security Agency (CISA) has recently developed this concept further, and at Red Hat we are embracing it in our products and cloud services.Secure by default pro

Changing systems passwords is a common task that all systems administrators must do to keep up with all the latest security policies. Now with secrets being managed by the secrets management system, we need a way to integrate with that to keep and manage all the secrets safe while updating the systems passwords in a secure, safe and automated way to stay compliant with all the rules and regulations.Red Hat Ansible Automation Platform makes this easy; there are so many ready-made playbook examples available to update any managed platform, such as Linux, Windows and many network devices. ht
