Key Highlights of RHEL 9.3

RHEL 9.3 ships with new versions of software including Python 3.11. Node.JS 18, GCC 12, Perl 5.36, Ruby 3.1, PHP 8.2, and many more.

Security Enhancements

With Red Hat Enterprise Linux 9.3, the OpenSSH configuration blocks remote login by the root user using password authentication. This prevents attackers from breaching the system using brute-force attacks.

In addition, SELinux policies have been improved to boost security. OpenSSL 3.0 introduces a provider concept, a new versioning scheme, and improved HTTPS. Built-in RHEL utilities have been recompiled to use OpenSSL 3.0 As a result, users can now benefit from the new security ciphers used for encryption.

Monitoring

The Red Hat Enterprise Linux 9.3 web console provides enhanced monitoring and performance metrics pages that help in identifying spikes in CPU, disk, memory, and bandwidth utilization. Furthermore, these metrics can be exported to the Grafana server for better visualization.

The web console now supports live kernel patching. You can apply the latest critical system patches without rebooting or interrupting services in the development or production environment.

Image Builder Tool

The image builder tool allows users to create custom RHEL system images in multiple formats both for minor and major releases. These images are compatible with major cloud providers such as AWS and GCP. This makes it possible to quickly spin up customized RHEL development environments on-premise and on cloud platforms.

In addition, you can also create bootable ISO installer images which are packaged in a tarball format. You can use these images to install RHEL on bare-metal servers or as a guest machine on top of a hypervisor such as VMware.
