Red Hat® Enterprise Linux® provides a flexible and stable foundation to support hybrid cloud innovation, allowing organizations to build security and compliance into the infrastructure from the time of development and maintain stability throughout the production lifecycle. Teams can build, deploy, and manage applications and critical workloads more quickly and efficiently with a consistent experience across physical, virtual, private, and public clouds, and edge deployments.

This e-book examines the essentials of Red Hat Enterprise Linux across 9 distinct areas that affect enterprise operations in a hybrid cloud environment. These practical tips help teams boost performance and simplify  lifecycle management across datacenter, cloud, and edge environments, so they can maximize Red Hat Enterprise Linux deployments from development to security. 

8 tech tips to advance security and compliance

When common vulnerabilities and exposures (CVE) volume rises and findings arrive more quickly than teams can often patch, it can cause compliance checks to fail when the running system has drifted from the policy. These 8 Red Hat Enterprise Linux capabilities help teams lock in configuration, contain what can execute, patch with less downtime, and prove it—using what’s already in the subscription.

1. Prepare cryptography for future threats

Red Hat Enterprise Linux system-wide cryptographic policies provide a consistent way to manage cryptographic settings across applications and protocols. With a single command, teams can apply a predefined policy across systems or create a custom policy for specialized requirements.

Red Hat Enterprise Linux 10.1 allows for post-quantum cryptography (PQC) algorithms in predefined policies by default. Support for Module-Lattice-Based Key-Encapsulation Mechanism (ML-KEM) key exchange and Module-Lattice-Based Digital Signature Standard (ML-DSA) digital signatures can help organizations begin protecting systems and data against future quantum threats.

Learn more about PQC in Red Hat Enterprise Linux.

2. Simplify FIPS compliance

Federal Information Processing Standards (FIPS) is a requirement for nonmilitary federal agencies and government contractors. Red Hat provides FIPS 140-2- or FIPS 140-3-validated cryptographic modules across supported Red Hat Enterprise Linux releases. FIPS mode helps standardize the use of approved cryptographic algorithms and required self-checks across the operating system (OS), reducing the need to configure applications individually.

Explore Red Hat Enterprise Linux FIPS certifications.

3. Isolate containers with SELinux, then customize the policy

Security-Enhanced Linux (SELinux) is an implementation of mandatory access control (MAC) in the Linux kernel. Red Hat Enterprise Linux containers run with SELinux by default. This includes an additional layer of security in the OS and helps prevent containers from breaking out and overwriting the underlying host OS or other containers on the system. Udica, a tool for generating SELinux security policies for containers, allows teams to analyze a running container and auto-generate a policy with container-specific SELinux rules. This simplifies policy writing and reduces risk by curtailing the need to run containers with superuser privileges.

8 tech tips that simplify container and OS management

Standardizing on trusted Red Hat Universal Base Images and tools, provides consistent operational environments, helps reduce security risk by limiting unverified dependencies, and connects traditional container workflows with modern image-mode OS deployments. 

1. Reduce privileges with rootless containers

Podman and other Red Hat Enterprise Linux container tools let users run containers without root privileges on the host. User namespaces map container users to non-root host users, limiting what containerized processes can access and reducing the potential impact of a compromised workload.

Learn more about rootless containers.

2. Standardize on Red Hat Enterprise Linux container images

Red Hat Universal Base Images (UBI) provide a redistributable, Red Hat Enterprise Linux-based foundation for building and deploying containerized applications—and, in image mode, for building the OS itself. If an application is already packaged in the RPM Package Manager (RPM) format, containerizing it can be as straightforward as installing that software into a UBI and running it.

Explore Red Hat Universal Base Images.

3. Build the OS like an application

With image mode, start with a Red Hat Enterprise Linux bootc base image and use a Containerfile to add the packages, applications, and configurations the system needs. Build and test using familiar tools such as Podman and Red Hat OpenShift®, then store the resulting image in a container registry, producing deployment-ready formats for bare-metal, VMs, cloud, and edge.

Learn how to build and test bootc images.

4. Automate updates and reduce manual work

Configure container workloads to automatically check, download, and redeploy newer images with Podman auto-update. For image mode systems, store Containerfiles in source control and use continuous integration and continuous deployment (CI/CD) or GvitOps workflows to build, test, and promote OS updates, with automatic updates and rollback for a predictable path back if needed.

Watch and learn more about container automation.

5. Reduce configuration drift

In image mode, most of the root file-system is immutable by default, with persistent configuration and data stored in locations such as /etc and /var. Making OS changes during the image build and deploying the complete system as a unit keeps systems starting from a consistent, reproducible state.

See how image mode can improve security and reduce drift.

6. Maintain compatibility across versions

Red Hat works to maintain compatibility across a range of major Red Hat Enterprise Linux versions, giving teams flexibility when upgrading container hosts and images. Matching major versions between image and host is recommended and is required for privileged containers. Mixed-version configurations are subject to the conditions in Red Hat's container compatibility policy.
