Simplified automation and managementRedHat team remain committed to providing Operations teams with tools and best practices to make the most efficient use of their most valuable resource – time. In support of this goal, they continue to focus on making RHEL easier to automate and deploy at scale. Some of the new items you’ll see in RHEL 9 Beta include:
- Enhanced web console performance metrics — Access to additional information will allow you to better identify the potential causes of performance bottlenecks. They’ve also made it easier to export these data to leading analysis and reporting tools like Grafana.
- Kernel live patching via the web console — Sensitive to system downtime? You can now leverage the power and ease of use of the web console to also apply live kernel updates.
- Streamlined image building — You’ll find several image builder improvements in RHEL 9 Beta, including the ability to build RHEL 8 and RHEL 9 images via a single build node, better support for customized file systems (non-LVM mount points) and bare metal deployments.
Enhanced security and complianceSecurity remains one of the leading concerns for Red Hat customers, and RHEL 9 Beta delivers a number of capabilities to help increase peace of mind and help you meet your strict compliance requirements.
- Smart Card authentication via web console — Users can make use of smart card authentication to access remote hosts through the RHEL web console (sudo, SSH, etc.).
- Additional security profiles — To help achieve compliance with standards like PCI-DSS, HIPAA, and others. When coupled with intelligence gathering and remediation services such as Red Hat Insights and Red Hat Satellite, customers now have access to powerful tools to rapidly resolve compliance issues at scale.
- Detailed SSSD logging — SSSD, the built-in enterprise single-sign-on framework, now adds more detail for events such as time to complete tasks, errors, the authentication flow and more. New search capabilities provide admins the ability to analyze performance and configuration issues.
- Integrated OpenSSL 3 — Apply the latest security standards with the new OpenSSL 3 cryptographic frameworks. Built-in RHEL utilities have been recompiled to utilize OpenSSL 3 to provide organizations with new security ciphers for encrypting and protecting data.
- Integrity Measurement Architecture (IMA) digital hashes and signatures — You can now dynamically verify the integrity of the OS to detect rogue modifications across your infrastructure.
- SSH root password login disabled by default — RHEL 9 disallows users to log in as `root` with a password to prevent brute force attacks gaining access via passwords.
Improved container development
If you’re building applications with UBI container images you’ll want to check out the RHEL 9 Beta UBI base images. The standard UBI image is available, as are micro, minimal and the init image. To get the full experience, test the UBI images on a fully subscribed RHEL 9 Beta container host, which will allow you to pull additional RPMs from the RHEL 9 Beta repositories.RHEL 9 Beta also ships with cgroup2 by default and a recent release of Podman with new defaults for RHEL 9. Users will get signature and short-name (e.g.: ubi8 instead of registry.access.redhat.com/ubi8/ubi) validation by default when pulling container images, so this is a great opportunity to test container-based applications with the “out-of-the-box” configuration planned for RHEL 9.
