Red Hat Enterprise Linux 9 Released as Beta Version

Red Hat -Booth

Red Hat has released version 9 of its Red Hat Enterprise Linux (RHEL) solution as a beta. It runs on upstream kernel version 5.14 and includes quite some new security features. This version is intended for high-volume hybrid multicloud installations that span physical, on-premises, public cloud, and edge environments.

RHEL 9 Beta has a variety of security features that might help users get peace of mind and satisfy their stringent compliance needs. RHEL 9 Beta comes with the following capabilities:

  • Smart Card authentication via web console – Through the RHEL online interface, users may utilize smart card authentication to access remote hosts (sudo, SSH, etc.).
  • Additional security profiles – To assist with compliance with industry standards such as PCI-DSS, HIPAA, and others. Clients now have access to sophisticated tools to quickly handle compliance concerns at scale when combined with intelligence collection and remediation services like Red Hat Insights and Red Hat Satellite.
  • Detailed SSSD logging – SSSD, the built-in enterprise single-sign-on framework, now includes additional information about events like job completion time, faults, and the authentication flow, among other things. Admins may now investigate performance and configuration issues using new search features.
  • Integrated OpenSSL 3 – Use the updated OpenSSL 3 cryptographic frameworks to meet the most recent security standards. RHEL utilities have been recompiled to use OpenSSL 3, giving companies new security ciphers to encrypt and safeguard data.
  • Integrity Measurement Architecture (IMA) digital hashes and signatures – To identify malicious alterations throughout infrastructure, users may now dynamically validate the OS’s integrity.
  • SSH root password login disabled by default – To avoid brute force attacks using passwords, RHEL 9 prohibits users from logging in as ‘root’ using a password.

Live Kernel Upgrades, Enhanced Metrics

Red Hat has also aimed at making RHEL easier to automate and deploy at scale. Some of the new items that can be found in RHEL 9 Beta include:

  • Enhanced web console performance metrics – Access to additional information would allow users to better identify the potential causes of performance bottlenecks. Red Hat has also simplified the process of exporting this data to popular analysis and reporting tools like Grafana.
  • Kernel live patching via the web console – Concerned about system downtime? Users may now use the web console to perform live kernel upgrades.
  • Streamlined image building – The ability to produce RHEL 8 and RHEL 9 images on a single build node, as well as greater support for customized file systems (non-LVM mount points) and bare metal installations, are among the image builder advancements in RHEL 9 Beta.
